Why Is My Dog Constantly Scratching and Biting Himself and How to Help

If your dog won’t stop scratching, biting, or licking their skin, it’s only natural to feel worried and maybe even a little helpless. It’s one of the most common issues pet parents face, but thankfully, there are clear ways to uncover the cause and give your dog the relief they deserve.

According to the American Kennel Club, itching is often linked to allergies, parasites, or underlying skin conditions.

Let’s take a closer look at the most common reasons for constant itching and how you can help soothe your pup’s skin — from daily habits to vet-approved treatments.

1. Allergies

Allergies are one of the top culprits behind itchy skin. They can be triggered by:

• Food sensitivities (such as chicken, beef, or dairy)

• Environmental factors (pollen, grass, or dust)

• Flea bites (some dogs are allergic to flea saliva)

• Contact irritants (detergents, cleaning products, or floor sprays)

If your dog’s itching worsens after walks or playtime, allergens may be clinging to their fur.

by the door and give your dog a quick wipe-down after outdoor time. This helps remove dirt, pollen, and debris that could trigger irritation.

2. Fleas and Mites

Even with regular care, fleas, ticks, and mites can sneak up on dogs. These parasites cause intense itching that can lead to redness, bald patches, and skin irritation.

If you notice your dog scratching the same area repeatedly, inspect their skin for small dark specks or tiny moving bugs.

What to do:

• Ask your vet about safe flea and tick preventives

• Wash your dog’s bedding and vacuum frequently to eliminate eggs

3. Skin Conditions

Chronic skin problems such as dermatitis, hot spots, or bacterial infections can make your dog’s skin red, flaky, or inflamed. You might notice hair loss, scabbing, or an unpleasant odor.

These conditions often require veterinary care and sometimes medication, but you can help by maintaining good hygiene and checking your dog’s coat regularly.

Regular brushing, gentle cleansing, and using dog-safe wipes like Pet N Pet Grooming Wipes can go a long way in supporting skin health.

4. Dry or Flaky Skin

Dogs can get dry skin from low humidity, overbathing, or harsh shampoos. You might see dandruff-like flakes or notice rough, itchy patches.

Quick Fix:

• Use a moisturizing, pH-balanced dog shampoo

• Avoid overbathing; once every 4–6 weeks is usually ideal

• Keep your dog hydrated and ask your vet about adding omega-3 fatty acids

Pro Tip: Between baths, use Pet N Pet Grooming Wipes to freshen up your dog’s coat without stripping natural oils.

5. Skin Infections

Persistent scratching can sometimes lead to bacterial or yeast infections. Signs include redness, swelling, hair loss, or an unpleasant odor.

If you suspect an infection, schedule a vet visit. Your vet may prescribe antibiotics, antifungal treatments, or medicated shampoos.

To help prevent infections in the future:

• Keep your dog clean and dry after baths or playtime

• Wipe ears and skin folds regularly to prevent moisture buildup

Home Care and Prevention Tips

While some causes of itching require medical treatment, good grooming and home habits can make a big difference in your dog’s comfort.

Regular Grooming

Brush your dog’s coat several times a week to remove dirt, loose fur, and dander. Regular grooming not only supports healthy skin but also helps you notice any changes early.

Nutrition and Hydration

Healthy skin starts from within. Feed your dog a well-balanced diet rich in essential fatty acids and ensure they drink plenty of water. If you suspect a food allergy, your vet can recommend an elimination diet to pinpoint triggers.

Clean Environment

Keeping your dog’s living space clean can reduce allergens and prevent flare-ups.

• Wash bedding weekly in hot water

• Vacuum frequently to remove dust and pet dander

• Clean food and water bowls daily to prevent bacterial buildup

Say Goodbye to the Itch

Excessive scratching and biting can be frustrating for both you and your dog, but with a little patience and consistent care, most cases can be managed or even prevented.

By maintaining regular grooming habits, managing allergies, and keeping your dog’s environment clean, you’ll help your pup feel more comfortable in their own skin.
