An infestation of fleas can cause a lot of discomfort for your dog, resulting in significant health problems. Additionally, fleas can take over your home and be extremely difficult to eradicate. They can even cause skin issues for you and the rest of your family. As for ticks, if your dog steps one paw outside, then you’ll want to make sure you’re proactive in understanding the various preventative options. Ticks can cause infectious diseases that can enter the bloodstream, so it’s good to search yourself and your pets for ticks after any outdoor activity. Flea and tick preventative treatments can reduce the headaches associated with eliminating pesky critters from your home and dog. Learn more about your options in our flea and tick prevention reviews, including topical oils, collars, sprays, shampoos, dips, and more.

Types Of Tick Prevention (A Vet’s Expert Opinion)

Tick prevention comes in two types:

  1. Repellents (which keep ticks away)
  2. Acaricides (which kill the ticks).

According to veterinarian  Dr. Joanna Woodnutt, MRCVS, “A combination of both is the best way to prevent ticks on pets. Depending on the preventative you use, ticks may still attach and feed, as they must consume the acaricide from your pet’s bloodstream to die. The time from the bite to dying and dropping off varies from product to product, but seeing a tick on your pet doesn’t necessarily mean the product isn’t working. If you can only use one, use an acaricide – repellents don’t work on all ticks, and without an acaricide, your pet is still at risk.”

Woodnutt also says, “There are lots of fake anti-tick collars out there, as well as products that claim to use essential oils and other natural products. It’s best to avoid these. Not only do they have little scientific evidence that they will work, but they also haven’t been through the same testing procedures as drugs have, meaning they may have severe and unexpected side effects.”

Best Spray: Adams Plus

Adams Plus Flea Spray

From the makers of our recommended shampoo (above), this easy-to-apply spray gives your dog quick relief from biting fleas. It kills adult fleas, flea eggs, larvae, and ticks and breaks the flea life cycle for up to two months. It’s also helpful in repelling mosquitoes.


Products We Don’t Recommend

Collar: Bayer Seresto

This waterproof and odorless flea and tick collar kills fleas within 24 hours of initial application and reinfests fleas within two hours. It also prevents tick infestations within 48 hours after application and kills and repels reinfesting ticks within six hours. This collar lasts for eight consecutive months and comes in various sizes.

However, according to USA Today, this product has been linked to deaths, hair loss, rashes, and neurological side effects over the years, yet the EPA has not issued a warning. So, one of the products we recommend above may be a better choice.

Chew Or Topical: Bravecto

We do not recommend Bravecto due to ongoing concerns from our readers and a class-action lawsuit filed against the manufacturer, Merck.

Natural Flea And Tick Prevention For Dogs

Don’t want to cover your dog with potentially toxic chemicals? There are many more natural flea and tick prevention products on the market.

Some experts say essential oils work just as well. Cedarwood, lavender, lemongrass, and citronella are a safe way to go, but be sure to dilute them in olive oil or sweet almond oil before applying them to your dog.

We recommend soaking your dog’s collar in a bowl of water with one drop each of lemongrass and lavender once a week. Don’t overdo it, though, as a dog’s sense of smell is much more sensitive than yours.

If you’re looking for other natural options to prevent your dog from getting fleas and ticks, here are some of our recommendations. You can also learn more in our detailed article on homemade flea and tick prevention.

What’s The Best Flea Prevention For Dogs?

If you don’t want a major flea infestation in your home, it’s crucial to know how to prevent fleas on dogs. Every female flea can lay up to 600 eggs in her lifetime. It’s frightening to think about the possibilities. Some preventative measures you can take to avoid fleas are the same for ticks (see below), but with different pests come various problems to conquer.

How To Apply Flea & Tick Treatment For Dogs

How you apply depends on the type of treatment and product you use. Read the directions on the package carefully to ensure you are using the treatment correctly and the method works properly.

How Does Flea & Tick Medicine Work

How the treatment works also varies depending on what type of product you use (or a combination of treatments). Typically there is an active chemical in topical medications called Fipronil that goes after the nervous system of the parasites to paralyze and kill them. Shampoos and sprays go an extra step by adding a barrier of scents that deflect, attracting fleas and ticks to dogs’ bodies.

Safeguard Your Yard From Wildlife

Since fleas spread like wildfire, it’s essential to limit wildlife access to your yard. Opossums, raccoons, skunks, deer, coyotes, and even untreated cats and dogs can easily shed flea eggs into a yard. Consider fencing off your yard, for starters. And your local nursery landscape professional may have some tips — specific plants and other landscaping options can help deter animals from your yard.

Use Flea Control On Your Dog

Consider using one of the best flea and tick treatment for dogs products we’ve reviewed above. These include topical oils, collars, sprays, shampoos, and more. You can also give your pup oral medications that work to control fleas.

If You Find Fleas, Act Fast

Don’t wait if you find even one flea on your dog or in your house. Where there’s one flea, there are likely more fleas or eggs. Treat your pup with a flea control product that kills live fleas and eggs. And be sure to check out our article on how to get rid of fleas in your home.

Consider Professional Pest Control

If you have a severe problem, you may want to get professionals to treat your yard and house. But do your homework about what kinds of chemicals they use to ensure they are safe for your family members and pets. Some companies may offer natural extermination remedies instead of toxic chemicals. You can also consider going the DIY route by purchasing pet-friendly pest control products.

What’s The Best Tick Prevention For Dogs?

You can take several proactive measures to protect your dog from tick-infested areas.

Avoid Certain Ecosystems

This tip may seem like a no-brainer, but it’s important to remember. Keep your dog away from natural tick habitats. Ticks thrive in dense, wooded, and vegetative areas. Avoid woods, tall grasses, overgrown shrubs, and decaying leaves on the ground when walking your dog. If you take your pup hiking, ensure he stays on the trail. And if he strays off-trail, check him thoroughly for ticks before getting home.

Have A Well-Kept Yard

Maintain a tick-free yard. If you have a large, open lawn, you shouldn’t have tick problems (as long as you keep your lawn trimmed regularly). Ticks don’t typically live out in the open. But if your yard borders a wooded area or you have lush gardens and shrubs and shady areas with decaying leaves, your dog is at risk if he roams your yard.

Rake up decaying leaves and keep your garden area and shrubs well-groomed. Another great tip is to make sure your outdoor trash cans have tight lids to keep away rodents and their accompanying ticks from your yard.

Check Your Dog For Ticks Daily

Be sure to check your dog’s head, neck, belly, tail, toes, and in and around ears. Separate the fur with your fingers and check under their collar to ensure ticks aren’t attached to the skin.

Consider Professional Yard Pest Control

Many pest control companies can treat your yard for both ticks and fleas. But first, do your homework about the types of chemicals they use. Some companies offer more natural treatment options that use essential oils or other natural ingredients. We recommend Sunday for offering pet-friendly products. Learn more about their full line of lawn care, including pet control, in our in-depth review of Sunday.

Our Personal Experience With Sunday Nix Ticks

sunday lawn mosquito ticks jpg

“Sunday sent me Nix Ticks in exchange for an unbiased review. My yard used to be entirely open, so ticks were never really an issue. As I’ve added more shrubs and plants, I’ve seen more ticks around. Nix Ticks has been an easy way to keep the ticks away. The bottle attaches to the hose, and then you spray it directly onto your lawn, shrubs, and trees. I avoided spraying areas with flowers (as the label states). So far, it’s worked great, and my dog hasn’t had a single tick on her this summer. I’ll need to reapply it in 2-4 weeks to keep the little critters away.”

Do Indoor Pets Need Flea & Tick Prevention?

Ticks and fleas have been found on indoor-only pets, and it’s thought they’ve been carried in on clothing. However, depending on your location, it’s not necessary for every animal to have flea & tick protection all year. It’s all about assessing an individual animal’s risk,” says Woodnutt.

Flea & Tick Prevention Is Critical: A Personal Story

Sally Jones & her dog

Every year the threat of disease-ridden ticks and fleas becomes more ominous, especially where my family and I live in Virginia. While we have a beautiful scenic view of the Blue Ridge mountains from our home, with deer often in our backyard, our lawn backs up to tall grasses and woods that attract ticks and other pests. Tiny loves to roam our surroundings, but he’s brought unwelcome pests into our home.

One spring, after finding many ticks in our house (and on me) — and having one of my daughters with suspected Lyme disease — I had had enough. So I searched for preventative measures to rid Tiny of his (and our family’s) ongoing pest problem. We followed these proactive measures and saw a big difference. Don’t let this happen to you, and stop the infestation before it begins.
