Unvaccinated Dogs: Risks, Realities & The Debate Some Pet Parents Face About Vaccines

When you purchase through links on our site, we may earn a commission. Here’s how it works.

Unvaccinated dogs spark some of the fiercest debates in the field of pet care. Some owners see vaccines as non-negotiable protection against serious communicable diseases. Others worry about side effects, over-vaccination, or a system that feels more about profit than pets.

But what really happens if you don’t vaccinate your dog? From health risks and legal trouble to the growing “no-vax” movement, here’s what every dog parent should know.

What Happens If You Don’t Vaccinate Your Dog?

Choosing to skip shots isn’t just about your own pet. The effects ripple through your household, your neighborhood, and your wider community.

1. Risk Of Deadly Illnesses

Diseases like rabies are still out there. They haven’t disappeared. Unvaccinated dogs, especially puppies with immature immune systems, are far more vulnerable. Here’s what an unvaccinated dog is at risk for:

• Parvovirus (parvo) attacks the gut and immune system, leading to bloody diarrhea, dehydration, and often death.
• Canine distemper damages the respiratory, digestive, and nervous systems. Survivors may live with seizures or lifelong neurological issues.
• Rabies is almost always fatal once symptoms appear, and it can spread to humans.
• Canine adenovirus type 1 (infectious canine hepatitis) causes severe liver damage, fever, abdominal pain, and bleeding disorders.
• Canine parainfluenza (CPAV) is a highly contagious respiratory virus that can cause severe breathing problems and pneumonia.
• Leptospirosis is a bacterial disease transmitted through contaminated water and the urine of infected wildlife. It can lead to kidney failure or liver problems in dogs — and it’s zoonotic, meaning it can infect people, too.

Quick Fact: Even dogs in urban areas can contract leptospirosis from puddles, standing water, or rat urine.

2. Costly Vet Bills

Prevention through vaccination is often cheaper than the alternative. Treating diseases is expensive, and the outcome isn’t guaranteed.

For example, a single parvo hospitalization can cost $1,500 to $5,000 or more. That includes:

• 24/7 isolation care
• IV fluids
• Antibiotics and anti-nausea meds
• Constant monitoring

Even after thousands of dollars, survival is never certain. Many families end up with broken hearts and empty wallets.

3. Legal Trouble

Some vaccines are optional. Rabies is not. In nearly every U.S. state, rabies shots are legally required. If your unvaccinated dog bites a person, even accidentally, the consequences are serious.

You could face:

• Heavy fines
• Lawsuits
• Quarantine of your dog
• In some cases, mandatory euthanasia

Even the gentlest family dog can be caught in legal crossfire if rabies laws aren’t followed.

4. Community Safety

Infectious diseases don’t stay put. An unvaccinated dog that becomes ill can spread viruses through its saliva, urine, or feces. Every walk, every sniff, every shared water bowl becomes a risk.

Dog parks, boarding kennels, groomers, and even sidewalks can turn into hot zones. By skipping vaccines, you’re not just risking your own pet — you’re risking every dog they meet.

Some pet owners argue these risks are overstated. But history tells a different story. Rabies, once a common death sentence for dogs and humans in the U.S., only came under control after widespread vaccination campaigns. Without vaccines, we’d be turning back the clock.

Vaccine Cost Breakdown: Prevention vs. Treatment

For many pet parents, cost is one of the biggest factors in the vaccine debate. But when you compare the price of prevention to the cost of treatment, the math is clear.

The Price of Prevention

Core vaccines usually cost $20–$50 per shot. A full puppy series may cost a few hundred dollars in total, depending on your veterinarian and location. Even with boosters, vaccines remain one of the most affordable parts of veterinary care.

The Price Of Skipping

If a dog catches a preventable disease, the costs skyrocket:

• Parvo: $1,500 to $5,000 for hospitalization, with no guarantee of survival.
• Leptospirosis: Hospitalization for severe cases can cost $2,000 to $4,000 or more. On top of that, it’s zoonotic, so infected dogs may expose their families to the disease.
• Distemper: Often untreatable, leaving lasting neurological damage or death.
• Rabies: Almost always fatal once symptoms appear — and may require quarantine or euthanasia if your dog bites someone while unvaccinated.

Pet Insurance Pays Off If You Start Early

Many owners skip pet insurance until their dog is older or already sick. However, by then, pre-existing conditions aren’t covered. Enrolling your pup when they’re young and healthy helps keep premiums lower and ensures that illnesses like parvo, cancer, or hip dysplasia are covered later in life.

Think of it as an additional layer of protection, alongside vaccines. See our reviews of the best pet insurance companies to protect your pup early. You can also add on a wellness plan to some companies’ policies to help cover the cost of vaccinations, wellness exams, and more.

Do Dogs Really Need Vaccines — Or Are We Overdoing It?

Here’s where controversy heats up. Some veterinarians advocate for yearly vaccinations, while skeptics question: Do dogs truly require vaccines that frequently? Or do dogs really need shots at all beyond the puppy stage?

• Pro-vaccine stance: Regular boosters help maintain high immunity, especially for community dogs exposed to kennels, groomers, and dog parks.
• Skeptical stance: Some research suggests certain vaccines may last 3–7 years. Over-vaccination, critics say, can stress the immune system or trigger rare side effects.

A growing middle ground is titer testing, a type of bloodwork that checks if your dog still has immunity. This lets owners avoid unnecessary shots while staying protected.

5 Main Arguments From The “No Vax” Side

Not every dog owner agrees with vaccinating their dogs. Those who choose to raise unvaccinated dogs often point to the same core arguments. Here’s how those beliefs usually break down:

1. Belief In “Natural Immunity”

Some owners believe that a strong, healthy dog can naturally fight off disease without intervention. They may lean on raw feeding, supplements, or genetics, arguing that nature provides everything a dog needs to stay protected.

However, while a solid immune system can help fight infections, diseases like parvovirus or rabies can overwhelm even the healthiest pets. Once exposed, “natural immunity” is rarely enough.

2. Fear Of Side Effects

Vaccine reactions are rare, but they do exist.

Reports of side effects range from mild (soreness, fatigue, fever) to severe (anaphylaxis, seizures, or autoimmune flare-ups). These stories circulate quickly online, fueling fears that vaccines cause more harm than good.

While most reactions are short-lived and manageable, the possibility of a severe reaction can be enough to deter hesitant owners from saying yes.

However, according to a large-scale 2023 study published in the Journal of the American Veterinary Medical Association (JAVMA), mild to moderate adverse reactions only occurred in 0.19% of dogs, and serious vaccine reactions were very rare.

3. Mistrust Of The Veterinary Industry

Some critics argue that frequent boosters are more about money than science. They believe the veterinary industry pushes unnecessary vaccines to generate profits, rather than tailoring care to each dog’s real needs.

This mistrust often grows when owners feel pressured during appointments, or when veterinarians don’t take the time to explain why certain vaccines are recommended.

4. Turning To Holistic Alternatives

Another common argument comes from the holistic side of pet care.

These owners opt for natural diets, herbal remedies, and homeopathy instead of conventional vaccines. They believe a strong foundation of wellness makes vaccines unnecessary.

However, while nutrition and natural care can certainly support health, no diet, herb, or supplement has ever been proven to prevent rabies, parvovirus, or distemper.

5. “Are Vaccines Even Necessary Anymore?”

Another common argument is that some diseases are now so rare that the need for vaccines is outdated. Common claims include:

• Distemper is seldom seen by many vets in wealthier countries.
• Leptospirosis is said to be rare, and critics argue its vaccine can cause more adverse reactions than benefits.
• Parvovirus, they claim, is “rarely a problem” in healthy adult dogs.

From this perspective, the risk of vaccinating seems to outweigh the benefit.

Counterpoint: Rare Doesn’t Mean Gone

Vaccines have indeed pushed many of these diseases to very low levels in developed nations. But that’s precisely because widespread vaccination built herd immunity.

When vaccination rates drop, these illnesses quickly resurface. For example:

• Parvovirus outbreaks still devastate shelters and kennels, killing thousands of puppies every year in the U.S.
• Leptospirosis has been on the rise in some cities (e.g., Chicago, New York, and Los Angeles), with urban rats spreading it through contaminated water.
• Distemper continues to appear in wildlife reservoirs (like raccoons and foxes), meaning dogs are never fully free of exposure risk.

In short, the reason many pet owners don’t see these diseases is because vaccines are working — not because they’re unnecessary.

Science Spotlight: The AVMA warns that parvo, distemper, and leptospirosis outbreaks still occur in the U.S. every year, most often in communities with low vaccine coverage.

What Science Actually Says (And Where Debate Gets Misused)

Let’s be clear up front: there are no credible, peer-reviewed studies that support a total anti-vaccine stance for dogs.

Across the board, from the AVMA, the World Small Animal Veterinary Association (WSAVA), the Centers for Disease Control and Prevention, and top veterinary schools, the consensus is that core vaccines (rabies, distemper, parvovirus, and adenovirus) are both safe and essential for protecting pets and the wider community.

But there are areas of research that sometimes get pulled into anti-vax arguments, even though the studies never claimed vaccines were unnecessary. Here’s where the nuance lies.

Duration Of Immunity (DOI)

Some vaccines last longer than once thought.

Long-term research by Ronald Schultz, DVM, and other immunologists shows immunity from certain core shots (like parvo, distemper, and adenovirus) can last 3–7 years or more. That’s why the AAHA and many veterinarians now recommend 3-year protocols instead of annual boosters.

Anti-vaccine groups often misuse these studies to argue that vaccines aren’t needed at all when, in reality, they support smarter, evidence-based scheduling.

Adverse Events Reporting

Yes, vaccine reactions can happen.

Studies have tracked millions of dogs after vaccination. The vast majority of side effects are mild: temporary soreness, fatigue, or fever. Severe reactions (like anaphylaxis or autoimmune flare-ups) are rare but can occur.

For example, the 2023 JAVMA study found that only 0.006% of dogs had an anaphylactic reaction. It also found that smaller dogs (e.g., French Bulldogs, Dachshunds, and Boston Terriers) receiving multiple vaccines in a single visit faced the greatest risk for a reaction.

These findings inform safer practices, but they don’t undermine the importance of vaccination.

In fact, there’s evidence that canine vaccines are getting safer. The researchers of the 2023 JAMVA study had previously done a similar study published in 2005. The rates of all adverse vaccination reactions fell from 0.38% in 2005 to 0.19% in 2023, according to findings.

Concerns About “Over-Vaccination”

Some holistic vets warn that repeating unnecessary boosters may stress the immune system.

The science here is limited. There’s no solid evidence that routine vaccination causes widespread harm. However, the concern has led to a shift toward tailoring schedules to the individual dog, rather than administering blanket yearly shots.

Quick Fact: The WSAVA guidelines specifically caution against automatic annual revaccination, recommending risk-based schedules instead.

The takeaway: mainstream veterinary science fully supports vaccines as critical. But research on schedules, immunity duration, and rare side effects often gets twisted into “anti-vax proof” when it was never meant to be used that way. Studies are about making vaccines safer and smarter — not about abandoning them.

What Is Titer Testing (And Why Is It Controversial)?

Not every dog owner feels comfortable automatically revaccinating year after year. That’s where titer testing comes in.

What Titer Testing Means

A titer test is a simple blood test that measures the level of antibodies in your dog’s system. If antibodies are present at a high enough level, it typically means your dog remains protected against that disease.

Titers are most often used for:

• Parvovirus
• Distemper
• Adenovirus

Titer testing is less reliable for diseases like leptospirosis or kennel cough, where immunity fades more quickly and does not rely on a lasting, measurable antibody response.

Quick Fact: A positive parvo, distemper, or adenovirus titer is widely considered reliable proof of protection, according to Today’s Veterinary Practice.

Why Some Owners Prefer It

For vaccine-cautious owners, titers feel like a middle ground:

• Avoids unnecessary boosters
• Reduces worry about “over-vaccination”
• Offers peace of mind that their dog is still protected

Many veterinarians now offer titers as part of wellness checkups, especially for senior dogs or those with a history of vaccine reactions.

Why It’s Still Controversial

Despite its benefits, titer testing comes with caveats:

• Cost: Titers can cost more than a booster shot.
• Incomplete protection: Not all diseases are reliably measured by titers. A dog might show antibodies but still lack full immunity.
• Legal limits: For rabies, titers aren’t accepted in many jurisdictions. Even if your dog shows immunity, they must be vaccinated to stay compliant with the law.
• Veterinary debate: Some veterinarians worry that owners may misuse titers as a reason to skip vaccines altogether, leaving dogs underprotected.

Some veterinary associations, such as the American Animal Hospital Association (AAHA), find them unreliable; however, other organizations, including the World Small Animal Veterinary Association (WSAVA) and many veterinarians, support their use to determine when a dog is protected from a virus and doesn’t need a booster vaccination.

The controversy stems from concerns about the accuracy of interpreting test results, differences between lab results, and differing opinions on whether titers are sufficient to prove immunity for legal requirements.

Titer testing isn’t a replacement for vaccination. Instead, it’s a tool — one that can help avoid unnecessary shots while still protecting dogs from serious disease. Used wisely, it’s part of a tailored approach to health, not a way to sidestep vaccines altogether.

Titer Testing vs. Revaccination: Pros & Cons

	Titer Testing	Revaccination
What it is	Blood test measuring antibody levels	Injection that stimulates new immunity
Best for	Core diseases (parvo, distemper, adenovirus)	Core + non-core diseases (rabies, lepto, bordetella, etc.)
Cost	Often more expensive than a shot	Generally cheaper per visit
Accuracy	Reliable for some viruses, less so for others	Proven protection against targeted diseases
Legal acceptance	Not accepted for rabies in many places	Required by law for rabies in many states
Usefulness	Helps avoid unnecessary boosters	Only guaranteed way to ensure ongoing protection
Controversy	Some owners use it to justify skipping vaccines	Criticized for potential “over-vaccination” if done too often

Research Shows Vaccine Hesitancy For Dogs Is Growing

A 2023 study by researchers at the Boston University School of Public Health, published in the journal Vaccine, surveyed 2,200 U.S. dog owners and uncovered striking levels of vaccine hesitancy:

• Nearly 40% believed canine vaccines are unsafe
• Over 20% thought they’re ineffective
• 30% viewed them as medically unnecessary
• About 37% even believed vaccines could cause dogs to develop autism — a claim with no scientific basis
• Overall, more than 52% of respondents expressed some form of hesitation toward vaccinating their pets

Researchers also flagged a “spillover effect:” owners skeptical of human vaccines (like childhood or COVID-19 shots) were significantly more likely to distrust pet vaccines and oppose rabies vaccination campaigns.

The BU survey isn’t alone. A 2022 JAVMA study of over 1,000 U.S. veterinarians found similar patterns of owner hesitancy, with safety concerns and mistrust being the primary drivers of the trend. The authors warned that rising skepticism could weaken herd immunity in pets and threaten rabies control nationwide.

Just as in human medicine, herd immunity is important. The more vaccinated dogs in a community, the less chance a virus has to spread. Unvaccinated dogs indirectly benefit from the protection provided by the majority. However, once vaccination rates drop too low, outbreaks tend to recur.

Together, these studies show that vaccine hesitancy isn’t just online chatter — it’s a measurable, growing issue with potential public health consequences.

The Psychology Of Vaccine Hesitancy

If the science is clear, why do so many pet owners still hesitate to vaccinate their pets? Studies, such as the 2023 Boston University survey and the 2022 JAVMA study, show that hesitation isn’t just about facts; it’s also about feelings, trust, and personal experience.

Fear Of Harm

Stories of dogs reacting badly to vaccines spread fast online. Although serious side effects are extremely rare, the possibility of harm feels very real to a concerned owner.

For many, a single anecdote about a dog that got sick after a shot outweighs decades of research showing that millions of dogs have been protected safely.

Mistrust Of Institutions

Some pet parents question the motives behind vaccine recommendations. They see frequent boosters as profit-driven rather than science-based.

This mistrust often grows when owners feel rushed through vet visits, or when the risks and benefits aren’t explained clearly. Without trust, even well-meaning advice can sound like salesmanship.

Spillover From Human Vaccine Debates

The BU survey revealed a “spillover effect:” people who were skeptical of childhood or COVID-19 vaccines were significantly more likely to doubt pet vaccines as well. This shows that vaccine hesitancy doesn’t exist in isolation — it’s shaped by broader cultural and political debates.

Is It Safe To Have An Unvaccinated Puppy With A Vaccinated Dog?

The short answer is: it depends. Some owners choose strict isolation until the final puppy shots are done. Others allow controlled interactions with trusted, fully-vaccinated household pets. The risk is never zero.

• A fully vaccinated adult dog is less likely to carry or spread disease, but they can still act as “silent carriers.”
• Puppies, who have immature immune systems, face the highest risk. Parvo and distemper often strike hardest between 6–16 weeks.
• Even brief contact at a park, daycare, or with visitors’ dogs can be dangerous until core vaccines are completed.

Can Unvaccinated Cats Be Around Dogs Safely?

If you share your home with both cats and dogs, vaccination decisions can get complicated fast. Many owners wonder: Does an unvaccinated cat put their dog at risk — or vice versa?

The truth is a bit more nuanced than yes or no. Here’s what to know.

Shared Risks Between Cats and Dogs

Some diseases don’t respect species lines. Rabies, for example, can infect both cats and dogs — and people. Certain respiratory illnesses can also spread across species, especially in close quarters.

Different Disease Profiles

Dogs and cats face different viral threats. A cat isn’t at risk of canine parvovirus, but it can spread feline panleukopenia, calicivirus, or herpesvirus. These won’t affect dogs, but they can devastate other cats in the household.

So, while your unvaccinated cat might not endanger your dog directly, it can still trigger outbreaks among feline companions.

The Safer Bottom Line

Multi-pet homes are healthiest when all animals are up to date on their own vaccines, especially rabies. Vaccinating both cats and dogs reduces cross-species risks, protects the whole household, and helps prevent community spread.

Other Reasons To Vaccinate: Travel & Boarding Rules

Health risks aren’t the only reason to vaccinate. Sometimes the rules of the real world make the decision for you.

Airlines and Travel

Most airlines require proof of rabies vaccination for pets traveling in the cabin or as cargo. International destinations often demand even stricter records, sometimes including health certificates signed by a vet.

Boarding And Daycare

Kennels, daycares, and training facilities typically require:

• Rabies
• Bordetella (kennel cough)
• Distemper/parvo combination vaccines

Without current paperwork, your dog won’t be allowed through the door.

Everyday Activities

Even grooming salons often ask for vaccine records. The reality is that skipping vaccines can limit where your dog can go and what experiences they can have.

Core vs. Non-Core Vaccines: What’s Actually Essential?

Here are the current canine vaccination recommendations from the American Animal Hospital Association (AAHA).

• Core vaccines (recommended for nearly all dogs):
  • Rabies
  • Canine distemper
  • Canine parvovirus
  • Canine adenovirus (hepatitis)
  • Leptospirosis
  • +/- Parainfluenza (often included in combination core vaccines)
• Non-core vaccines (lifestyle-based):
  • Bordetella (kennel cough)
  • Lyme disease
  • Canine influenza
  • Rattlesnake vaccine

Learn more about these vaccines and diseases in our complete guide to dog vaccinations.

Puppy Vaccination Schedule

Here’s an example of a puppy shot schedule for the first year of life. Keep in mind that this schedule may vary by veterinarian and your puppy’s specific needs.

Age	Core Vaccinations	Non-Core Vaccinations
6-8 Weeks	1st DAP or DHPP*	Bordetella Parainfluenza
10-12 Weeks	2nd DAP or DHPP Leptospirosis	Lyme disease Canine influenza
14-16 Weeks	3rd DAP or DHPP Leptospirosis Rabies	Lyme disease Canine influenza

* DAP (also called DHP) is a combination vaccine for distemper, adenovirus (hepatitis), and parvovirus. Many vets may choose to administer the DHPP (also called DAPP or DA2PP), which also protects against parainfluenza.

Dog Vaccination Time Table

Below is a vaccination chart outlining the possible vaccines and the recommended administration times for each. This timeline may not apply to every dog, but it gives you an idea of various scenarios.

And remember, giving a dog too many vaccinations at the same time can result in side effects, so be sure to discuss spacing them out with your veterinarian, if possible.

Interactive Checklist: Is Your Dog Protected?

Wondering if your pup is truly covered? Run through this 1-minute checklist:

• Has your dog missed any core vaccines (rabies, parvo, distemper, adenovirus, lepto)?
• Does your dog go to the park, daycare, or dog-friendly events?
• Do you board your dog when traveling?
• Do you live in an area with wildlife (raccoons, foxes, coyotes)?
• Does your dog travel across state lines or internationally?

If you answered yes to even one of these, your dog faces a higher risk and likely needs more than the bare minimum vaccines.

Global Differences In Dog Vaccination

The vaccine debate looks very different around the world. In some countries, it feels optional. In others, it’s the only line of defense against deadly outbreaks.

North America

In the U.S. and Canada, vaccination is common and legally enforced. Rabies shots are required almost everywhere, and proof is needed for licensing, boarding, or travel. Most vets follow 3-year protocols for core vaccines.

Europe

Many European countries rely on titer testing instead of automatic boosters, tailoring vaccines to individual dogs. Still, rabies shots remain mandatory for international travel and in certain nations.

Asia

Asia carries the highest rabies burden worldwide. Countries like India, China, and Indonesia face major outbreaks due to under-vaccination and stray dog populations. Wealthier regions such as Japan and Singapore, by contrast, enforce strong vaccine laws and remain rabies-free.

Fast Stat: India accounts for 36% of global rabies deaths.

South America

Mass vaccination campaigns, particularly in Brazil and Chile, have significantly reduced the incidence of rabies. However, rural gaps remain, and parvovirus and distemper are still common in areas with low coverage.

Africa

Africa has some of the lowest vaccination rates, often under 20%. Rabies continues to kill more than 20,000 people annually. International campaigns focus heavily on raising coverage here.

Oceania

Australia and New Zealand are rabies-free but enforce strict import rules. Dogs entering must be vaccinated, microchipped, and often quarantined for a period of time. Locally, owners tend to focus more on lifestyle-based vaccines, such as leptospirosis or kennel cough.

Navigating The Middle Ground: 5 Practical Tips

If you’re undecided or want to minimize risks while avoiding unnecessary shots:

1. Prioritize core vaccines: Rabies, parvo, distemper, and lepto are too deadly to gamble with.
2. Use titer testing: Helps avoid unnecessary boosters without leaving your dog unprotected.
3. Consider your dog’s lifestyle: Boarding, grooming, daycare, or travel means higher exposure risks.
4. Space vaccines out: Ask your vet if spreading shots reduces stress on the immune system.
5. Track reactions: Keep a record of any side effects your dog shows — it helps guide safer future plans.

Ultimately, the most balanced approach may be one of informed choice: core protection, lifestyle-based decisions, and open conversations with a vet you trust.

The Emotional Side of the Vaccine Debate

At its core, this isn’t just about science. It’s about trust, fear, and responsibility.

• Some owners claim they’ve never vaccinated their dogs, yet they have lived long, healthy lives.
• Others share gut-wrenching stories of losing a young pup to parvo after just one unvaccinated walk in the park.

Both experiences are real. Both fuel the polarization.

And now, with both peer-reviewed veterinary research (JAVMA) and large-scale surveys (BU) documenting rising mistrust, the conversation is more emotionally charged than ever.

Frequently Asked Questions

Here are some of the most common questions owners ask about vaccines — along with clear, evidence-based answers. If you don’t see your question here, drop it in the comments and we’ll add it to the list.

What’s The Safest Age To Vaccinate A Puppy?

Puppies usually start receiving vaccines at 6–8 weeks of age, then receive boosters every 2–4 weeks until at least 16 weeks of age. This timing ensures coverage as maternal antibodies fade.

Can I Socialize An Unvaccinated Puppy?

Yes, but it has to be carefully controlled. Puppies are most vulnerable between 6 and 16 weeks, when their maternal antibodies are fading but their vaccine series is not yet complete.

You can introduce your puppy to:

• Trusted, fully vaccinated adult dogs in your household or circle
• Puppy socialization classes that require vaccine records

Avoid high-risk areas, such as dog parks, pet stores, or sidewalks, until the full vaccine series is complete.

Can I Legally Refuse Rabies Vaccines?

In most states, no. Rabies vaccination is required by law for all dogs, regardless of lifestyle.

If your dog bites someone and isn’t up to date, you could face:

• Mandatory quarantine
• Heavy fines
• Potential legal action
• In some cases, forced euthanasia of your pet

Can Indoor Dogs Skip Vaccines?

No. Even indoor-only dogs can be exposed to viruses via shoes, visitors, or wildlife that sneaks into the yard. Rabies is still required by law, regardless of lifestyle.

Are Vaccine Side Effects Common?

Most dogs tolerate vaccines without any issues. The most common reactions are mild and temporary: tiredness, soreness at the injection site, or a low-grade fever.

Severe reactions, such as anaphylaxis, hives, or autoimmune problems, are rare but possible. Vets are trained to treat them quickly.

Is Raw Feeding Or Holistic Care Enough?

No diet, herb, or supplement can replace vaccines in protecting against contagious, deadly diseases.

A balanced diet and natural care can support the immune system, but they won’t prevent communicable diseases.

What Every New Pup Parent Should Remember

The puppy stage is when vaccines are most important.. Protecting young dogs from parvo, distemper, and rabies gives them the best chance to grow into healthy adults. A few early decisions can help safeguard a lifetime of companionship.
