Why Is My Dog Biting Himself?

When your dog is itchy, he will scratch himself and rub against a surface with his paws and teeth to relieve the itching. But if you find your dog biting and chewing his body more than usual, you should be concerned.

Excessive skin biting and scratching can suggest a variety of health problems.

Reason 1: Parasites

A flea infestation is one of the most prevalent causes of your dog biting and scratching his skin. Fleas are parasitic insects that nibble and feed on your dog’s blood. 

A flea nibble on your dog’s skin may show as a tiny, raised red mark that will swell and become irritated if scratched. If your puppy ingests contaminated fleas while chewing at his skin, a flea infestation may lead to parasitic worms if left untreated. 

With high infestations, anemia can develop in young or smaller dogs. Flea allergic dermatitis, characterized by extreme itching, frequent licking and scratching, hair loss, and scab forms, can occur in sensitive people.

If your dog snores loudly, check its health. One of the causes your dog bites himself is because of his health.

Reason 2: Allergies

Your dog’s skin may become itchy and flaky due to allergies in the surroundings. A typical reason for excessive scratching and biting at the skin is allergies, which generally begin in your dog’s early years. 

Certain breeds, like Terriers, Beagles, Setters, and Retrievers, are also susceptible to allergies. Pollen, dirt, dust mites, trees, and certain foods are just a few of the things that might cause an allergic reaction in dogs.

Reason 3: Dry Skin

Dry skin is a common cause of itching in dogs. Inadequate bathing, environmental factors, or nutritional deficiencies such as a lack of omega fatty acids can all contribute to dry skin.

A number of these reasons sometimes cause dry skin.

Reason 4: Hormonal Imbalances

Dog skin is more vulnerable to infections due to hormonal changes. Thyroid hormone deficiency & overproduction of cortisol are the most typical hormonal causes. 

When the skin changes or frequent scratching is present, there will be a wide range of symptoms to go along with it.

For this issue, you should seek the advice of a veterinarian. Dogs, on the other hand, can be sensitive to unfamiliar environments. Since dogs are observant, you’ll notice an increase in yawns when it’s time for a vet visit.

Reason 5: Anal Glands Infection

When the anal glands aren’t frequently flushed, they can become a source of bacteria.

The bacteria cause itching on the dog’s back, particularly in the buttocks, tail, groins, and hind legs. Anal gland problems can be caused by a lack of exercise and a poor diet.

Reason 6: Psychological Reasons

Your dog’s behavior may signify stress, worry, or boredom, and he is licking or biting his skin to express these feelings. Excessive lapping and nibbling of the body can develop into an obsession if not treated and rectified. 

Also, your dog standing on you may have a psychological problem. You can work with your veterinarian and a dog trainer to develop a training plan and fix your dog’s bad habits.

6 Ways to Prevent Your Dog from Biting Himself

We’ve got some tips to keep your dog from biting itself. Here are a few ideas I have for you.

Tip 1: Buster Collar

The plastic “Buster Collar” is the most effective method for keeping your dog from biting himself. Many veterinary clinics have them on hand for just this reason. 

Having a buster collar on hand in an emergency is a good idea. Slip your dog’s regular collar through its loops, then put it back on your dog. It’s that simple! 

For the first few minutes, many pups will be bewildered by the new extension of their collar and may run into items on top of it. 

A temporary repair, of course, but it’s an excellent method to keep your dog from hurting themselves while you make an appointment with the vet.

Tip 2: Comfy Blow-up Collar

If you have a dog that isn’t a fan of the traditional “doughnut” kind of collar, you may want to try a blow-up “doughnut” collar instead. 

If your dog has a long neck or is remarkably flexible, you may consider using an alternative method for relieving his itch. If your dog can get past its current collar, you may always swap to a less-comfortable one.

Tip 3: Bodysuit

Using a medical bodysuit, canine jumper, or modified child’s t-shirt can keep your dog from licking and biting on skin irritations or injuries. This won’t stop a dog from nipping its back if the problem is with its legs or feet.

Tip 4: Barrel Mouthpiece

Not for long-term usage, but in an emergency, a muzzle can keep your dog from hurting himself while you’re at the clinic. The dog’s impulse to lick and gnaw at the area for unexpected foreign body infections, but keeping it clean is best. 

Never leave your pups unattended while using a muzzle, and only basket muzzles should be worn for more than a few minutes.

Tip 5: Bitter Spray

Bitter sprays suitable for pets can be used to break up the habit of licking or biting. The second layer of protection for your dog is best provided by applying them to a garment, including a sock or t-shirt.

Tip 6: Use Shampoo

If your dog has immediately begun chewing, give him a bath with dog-safe shampoo. This should remove pollen, burrs, and road dust from your dog’s coat. A skin-calming shampoo also may help relieve irritations.

You should be aware of how to bathe a dog properly.

This is a list of the finest current solutions. So utilize it now!

I hope this has satisfied your expectations.


How frequently should canines be dewormed?

Every three months, at the very least. Depending on your dog’s lifestyle, more frequent worming may be required, and it is suggested that you discuss this with your veterinarian if you are worried.

Is it possible to treat my dog for parasites without visiting the veterinarian?

Take your dog to the vet if you suspect worms or any of the symptoms mentioned above. Even if your dog is cured of intestinal worms with natural therapies, you should immediately take them to the doctor.

Is it necessary to bathe your dog every day?

Every four weeks is a reasonable rule of thumb to follow when bathing your dog, according to Wendy Weinand of Petco, the manager of grooming instruction for the company.
