4 Common Causes Of Sensitive & Itchy Skin
Watching your dog constantly scratch, chew, or lick their skin is stressful. It’s even worse when you don’t know what’s causing it. The truth is, there are many reasons dogs develop sensitive, itchy skin, and most of them are treatable. Let’s break down the most common causes.
1. Bacterial & Fungal Skin Infections
Bacterial and fungal infections are usually secondary problems that occur following another health issue that’s caused your dog to scratch his skin. Skin damage allows bacteria to proliferate, causing more itching and setting up a chronic problem.
Hot spots, also called moist dermatitis, are red, inflamed, irritated skin areas caused by infection, allergies, insect bites, or over-grooming.
2. Hormone Imbalances & Autoimmune Issues
Itchy, dry skin can be symptomatic of several health conditions caused by hormone imbalance, such as hypothyroidism or Cushing’s disease.
Some autoimmune disorders, such as lupus and pemphigus foliaceus, can cause a dog’s skin to become dehydrated, sensitive, and itchy.
3. Dry Skin
When a dog’s skin becomes dehydrated, it becomes itchy. What causes dry skin?
- Living in a dry environment
- Having too many baths
- Eating mediocre-quality dog food
- Genetics (e.g., many Yorkies have dry skin)
In some cases, you can improve your dog’s skin moisture by adding fish oil to his food and perhaps buying a humidifier for use in your home.
4. Allergies
Some dogs have allergies or intolerances that can cause their skin to become dry, sensitive, and itchy. Allergy symptoms can be caused by food, cleaning chemicals, shampoos, medication, pollen, grasses, fleas, etc. Allergies are actually one of the most common reasons for itchy skin in dogs.
See our guide on the best home remedies for your dog’s itchy skin, in addition to the shampoos I recommend below.
Types of Allergies
Flea Allergy Dermatitis (FAD)
A hypersensitivity to flea saliva that leads to intense itching, often around the tail and back legs.
Inhalant Allergy (Atopy)
Caused by pollen, dust mites, or mold. These typically show up as itching in the paws, ears, and belly rather than classic sneezing or runny nose symptoms.
Food Allergies
Proteins like chicken, beef, lamb, or grains can trigger reactions. These often cause both skin issues and GI upset.
Contact Allergies
Less common but can occur when dogs react to specific materials like flea collars, detergents, or grass. Usually, it results in localized irritation, especially on the feet and belly.
If you suspect your dog has allergies, don’t guess. Speak with your vet.
Managing Sensitive Skin: What You Can Do Right Now
Not sure where to start? These steps can help calm irritated skin while you work on long-term solutions:
- Switch to a gentle shampoo for dogs with sensitive skin
- Add fish oil or vitamin E supplements to meals
- Schedule a grooming appointment
- Clean your dog’s paws and belly after outdoor play using dog wipes
- Avoid over-bathing and harsh grooming products
- Consider switching your dog’s diet to a healthier choice
- Try an at-home allergy test or consult your vet for diagnostics
Grooming Tips for Sensitive Skin
A healthy coat and skin starts with regular grooming. Tangled, dirty fur can trap allergens and irritants close to the skin, making itching worse.
- Use a de-shedding tool to remove dead hair and dander
- Keep long-haired dogs brushed and knot-free
- Wipe down your dog’s paws and underbelly after walks to remove outdoor allergens
- Use vet-approved grooming wipes around the face and ears instead of shampoo
Matted fur also prevents air circulation and can trap moisture—creating the perfect environment for bacteria and fungi.
Can Shampoos Help?
In many cases, dog shampoo formulated especially for sensitive skin can help alleviate the problem. However, it’s always advisable to consult your vet to find out exactly what’s causing the itchiness before you head down the DIY treatment route.
Sometimes, a specialist veterinary dog shampoo that’s formulated to kill parasites, bacteria, or ringworm may be appropriate. Or a product that will combat the effect of allergies could be prescribed, together with a course of antihistamine drugs.
Why Regular Bathing Matters
Bathing helps rinse away allergens, bacteria, and irritants, but only if done correctly.
- Use a hypoallergenic, pH-balanced shampoo made for dogs
- Avoid human shampoos, which are too acidic for canine skin
- Don’t over-bathe — once every 3–4 weeks is usually enough unless otherwise advised by your vet
If your dog has active infections or chronic skin issues, your vet may recommend a medicated shampoo formulated for fungal or bacterial conditions.
What To Look For In A Skin-Soothing & Hydrating Shampoo
Choosing a gentle, nourishing shampoo for dogs with sensitive skin can make a big difference, especially if you know what ingredients to look for.
Colloidal Oatmeal: Your Best Bet
This is one of the most popular and effective ingredients in anti-itch shampoos. It’s ground into a fine powder and suspended in water, making it easier to absorb into the skin. Colloidal oatmeal shampoo helps:
- Calm inflammation
- Restore the skin’s natural pH
- Soothe hot spots and irritation
It also contains beneficial compounds like avenanthramides, flavonoids, and vitamin E—all known for anti-inflammatory and antioxidant effects.
Other Soothing Ingredients
- Aloe vera – calms and hydrates
- Chamomile – reduces irritation
- Allantoin – promotes healing
- Vitamin E – supports skin repair
- Burdock root – natural detoxifier and anti-inflammatory

Frequently Asked Questions
In this part of our guide, we answer some of the most commonly asked questions by dog owners whose pets suffer from the problem of sensitive, itchy skin. If you don’t see yours, just ask your question in the comments section. We’ll do our best to help you!
Why does my dog have sensitive skin?
Sensitive skin in dogs can be caused by allergies, parasites, bacterial or fungal infections, or poor grooming. Build-up of dirt and natural oils can also lead to irritation if not regularly cleaned.
Why does my dog have a skin allergy?
Allergies are often triggered by pollen, dander, flea saliva, certain foods, or medications. Some are inherited, so your dog’s skin issues might be genetic.
Should I make a homemade dog shampoo?
While you can find many DIY recipes online, dogs with itchy or sensitive skin usually do better with professionally formulated shampoos — especially those designed to soothe irritation and maintain skin health.
How often should I bathe a dog that has sensitive skin?
Avoid overbathing, as it can dry out your dog’s skin. Unless your vet recommends otherwise, once a month is usually enough for dogs with sensitive skin.
Should I use a conditioner with my dog that has sensitive skin?
Yes, as long as it’s formulated for sensitive skin. Look for conditioners with oatmeal, aloe vera, or other natural moisturizers to help soften the coat and reduce irritation.
Should I Change My Dog’s Diet?
A healthy, all-natural diet can go a long way in improving your pup’s skin. You may want to consider human-grade, fresh dog food, a limited-ingredient formula, or the best dog food for allergies. Also, speak to your vet about dog allergy supplements to help relieve sensitive skin.
