Reasons Your Dog Might Be Chewing Himself

It’s normal for dogs to chew and scratch themselves—on occasion. Like us, sometimes dogs just get itchy!

But other times, the scratching can be excessive and can even cause problems. If your dog seems to be scratching and chewing himself more than is normal, there are a few reasons why that might be.


If your dog is scratching and chewing on himself a lot, the usual culprit is allergies.

Yep, that’s right—just like humans, dogs can get allergies! And also like humans, allergies can be caused by a variety of things.

Some dogs are allergic to certain foods. Others have seasonal allergies like people. Also keep in mind that certain breeds tend to be more prone to specific allergies than others.

If the problem is allergies, your dog might have other symptoms too, though not always. He might wheeze, sneeze, cough, or have a runny nose or eyes.

If you think your dog is itchy because of allergies, then the most important thing is to determine what your dog is allergic to. You can then help him to avoid whatever triggers his allergies.

Dry Skin

You know how itchy you get when your skin is dry? Well, the same is true for your dog!

If your dog has dry skin, that could be the cause of his chewing and scratching. In that case you’ll likely see a lot of dandruff flaking off your dog.

There are different causes of dry skin. A common one is changes in weather. You’re probably familiar with how dry skin gets in the winter time. If you live in an area with low humidity, this can cause dry skin in your dog, too.

A lot of the time, a dog’s diet can be the cause of dry skin.

Skin Infections

Sometimes a dog’s itchiness is the result of skin infections. This can be caused by bacteria and fungus growing on your dog’s skin.

One example of a skin infection in dogs is pyoderma. This is when the hair follicles and surrounding skin become infected. It’s usually caused by something getting under your dog’s skin, a wound of some sort, or allergies.

If your dog seems super itchy, it could be because of parasites living on your dog’s skin. Yup—gross!

There are several different types of parasite that could be responsible. Fleas are one of the most common ones that show up on dogs. These are wingless insects, and can be extremely irritating for your dog. You might be able to see them bouncing around your dog, though they are very small—about the size of sesame seeds.

Ticks can also cause itching in dogs. If your dog spends a lot of time outside, you’ll want to check him over regularly for ticks. These insects can carry dangerous illnesses, and at the very least they’re irritating for your dog.

Your dog might also be affected by lice or mites. There are lots of different kinds of mites, and in severe cases your dog might experience mange.

It’s important to brush your dog frequently, and check him over for signs of parasites that might be living in his fur.

Boredom, Stress, or Anxiety

Most of the time, dogs scratch because they’re itchy. But sometimes scratching and chewing can be part of a behavioral problem.

This is especially true for chewing. Chewing releases endorphins in your dog’s brain, which makes your dog feel good. If your dog is stressed out, he might chew on himself to self-soothe.

He might also do it if he’s bored, just to give himself something to keep him occupied.


Sometimes a dog might chew or scratch himself because part of him hurts. If your dog is chewing because he’s hurt, he’ll likely show other signs of pain too. He might hide, shake, or lose his appetite.

Anal Gland Issues

It’s not pretty, but sometimes your dog’s anal glands can become plugged, causing discomfort. This discomfort might, in turn, lead your dog to chewing and scratching himself.

If your dog “scoots” his bum along the ground, that’s another sign he might be having some anal gland issues. The glands might also bleed or have pus form in serious cases.

Make Sure He Gets Enough Exercise

And don’t forget to provide mental exercise! Here are 10 brain games for dogs to play at home.

Relieve His Stress or Anxiety

If your dog is chewing to soothe himself, then you need to find the source of his anxiety and remove it.

Depending on what the source is, removing it might be enough. But sometimes the thing that’s causing your dog’s anxiety might just be a part of life, and something he needs to learn to deal with!

In that case, desensitization and counterconditioning are your best friends (well—aside from your dog). It means removing the stimulus causing your dog’s anxiety and reintroducing it in a slow, controlled, positive way. This is one of the most effective ways to help your dog get over his fears!
