Why Is My Dog Nibbling His Legs?

We all love dogs, and we want them to look and act their best for us – and our friends.

But when it comes to grooming, many dog owners are unaware of how important it is to keep their fur clean.

That’s why they often end up with dogs who have bald patches on their legs, face, ears, and even tail.

Itchy Skin

One of the most common problems experienced by pet parents is itching skin.

It can be caused by any number of conditions.

Dogs may experience itching due to fleas, ticks, food allergies, hairballs, ear mites, or an allergic reaction to something in their environment.

Flea Allergy

Fleas can cause itching for several reasons.

First, the fleas themselves can bite pets and then become engorged with blood.

The flea saliva contains anticoagulant chemicals that prevent the blood from clotting, allowing the flea to feed.

When this happens, the flea becomes irritated and begins looking for somewhere to rest.

When the flea bites the skin of the host animal, it causes a rash and redness around the bite.

This is referred to as “flea allergy dermatitis.”

If you suspect that your dog has fleas, make sure you contact your vet.

They can prescribe medications to control the problem, but they may also need to check your home for fleas and eliminate them.


Ticks can carry diseases such as Lyme disease, Rocky Mountain spotted fever, and ehrlichiosis.

These bacteria can affect humans and animals alike.

If your dog gets bitten by a tick, immediately wash the area thoroughly with soap and water.

You should remove the tick using tweezers and place it in alcohol or rubbing alcohol.

You can then place it in a plastic bag and take it to the doctor.

Food Allergy

Dogs can develop food allergies just like people do.

Food allergies are not uncommon among dogs.

Some foods that are known to cause allergies include beef, chicken, wheat, corn, soy, milk, eggs, potatoes, and other vegetables.

If your dog is allergic to one particular type of food, he may start licking his lips, scratching his ears, and scratching at his eyes.

He may also begin licking or chewing his paws, so you will find that he starts leaving hair along the floor where he has been walking.

Once your dog stops eating the offending food, he should feel better after he eats.


hairballs are one of the major causes of hair loss in dogs.

Hairballs form when your dog swallows too much hair while eating and then regurgitates it later.

The hair gets stuck in the throat, which causes inflammation and irritation.

When the hairball is large enough, it can block the esophagus.

Your pet may vomit, cough up blood, or show signs of pain.

You can try giving your dog a laxative to get rid of the hairball.

If this doesn’t work, you can give him a special medicated shampoo that helps break down the hair.

Be aware, though, that some shampoos contain ingredients that aren’t safe for puppies.

Talk to your vet about what kind of shampoo is best for your dog.

Ear Mites

Ear mites are parasites that live in the outer ear canal of your dog.

They are usually found in combination with another parasite called sarcoptic mange (scabies).

Ear mites are very small and hard to see without a magnifying glass.

They can easily be missed by vets because they don’t appear to be anything out of the ordinary.

However, they can cause severe itching and discomfort in your dog.

They can also spread to other parts of the body.

To treat ear mites, your vet will use a cotton swab dipped in a solution of iodine-based medication to gently wipe away the parasites.

Afterward, she will apply a topical antihistamine cream to help relieve your dog’s discomfort.

Be aware that ear mite treatment isn’t always effective, especially if your dog has multiple cases of ear mites.

Allergic Reaction

Your dog may also suffer from an allergic reaction if he has eaten something that upsets his system.

For example, if he ate grass from the yard and then vomited, he may have had an allergic reaction to the grass.

Sometimes, even if a dog doesn’t eat the grass, he may still react to it.

In these situations, you should contact your vet right away.

There are several different types of allergic reactions that your dog may have.

If your dog has an allergic reaction to the grass, it could cause swelling, hives, vomiting, diarrhea, and breathing difficulties.

One of the most common causes of itching in dogs is an allergy.

An allergic reaction occurs when the immune system reacts to something it perceives as foreign.

The body then releases histamines and other chemicals to fight off the perceived threat.

This can result in inflammation in the skin, which causes redness, swelling, and sometimes hives.

Allergic reactions can also affect organs such as the eyes, nose, mouth, throat, stomach, intestines, liver, and lungs.

In severe cases, respiratory distress may occur.

The most common allergens include dust mites, pollen, mold, and feathers.

Other possible culprits include food particles, animal dander, perfumes, shampoos, soaps, detergents, and cleaning products.

Pets with long hair are more likely to become sensitised than those with short fur because longer hairs trap more dirt and debris.

Dogs with long coats are more susceptible to fleas and ticks and therefore need to be treated regularly.

Dogs with allergies should avoid contact with the offending substance until their symptoms subside.

If you suspect your dog has an allergy, speak to your vet about treatment options.

While there is no cure for allergies, your vet can prescribe antihistamines and corticosteroids to relieve symptoms.

You may also consider using oatmeal baths to moisturise the skin and prevent further irritation.

If you suspect that your dog might be suffering from allergies, you should take him to the vet immediately.

They will perform a full physical examination to rule out any underlying medical conditions that could cause the symptoms, including a tumour or infection.

Once these are ruled out, the doctor may recommend a trial course of medication to reduce the frequency and severity of the allergic response.


As you may know, anxiety can cause behavioral problems in dogs.

This includes obsessive behaviors like chewing his legs so he won’t scratch himself.

If a dog is anxious, he will pull at his coat, lick his lips, and paw at his body.

He will also try to escape from unpleasant situations by running away.

If you notice any of these behaviors in your pet, it might have something to do with anxiety.

Dogs can get anxious about things such as being left alone or in a new place (especially a strange one), being separated from their family members, or not getting enough exercise.

It could also mean that your dog has an underlying medical condition that needs to be addressed.

For instance, if your dog chews his paws because he gets separation anxiety, then he probably doesn’t like being left alone at home while you work or go out shopping.

You should talk to your vet about this possibility.


There are several causes of hair loss in dogs, including skin problems, stress, and boredom.

Many of these conditions can be treated by visiting your veterinarian.

The most common cause of hair loss in dogs is stress.

This can come in different forms, like separation anxiety, fear of new places or people, or over-grooming.

Another reason that may cause hair loss in dogs is boredom.

Dogs need exercise to stay healthy, but sometimes the time spent exercising them is not enough.

If you notice that your dog spends more time lying down than playing around, this could indicate that he needs some extra stimulation from you.

You could play fetch with him, take him out for a walk, or do something else fun together.

If your dog starts chewing his leg, it could mean he has an allergy or irritation.

He might also be bored or stressed.

Contact your vet about any concerns you have regarding your dog’s behavior.

Lack of Nutrition

Dogs need nutrition just like people do.

They also need plenty of water, which helps keep them healthy.

However, most dogs don’t get enough of these things in their food.

This lack of nutrition can lead to skin problems, such as dryness and itching.

Dry skin can lead to redness, scabs, and infections.

The lack of nutrition can also affect how well your dog’s teeth are able to work.

A tooth problem might cause your dog to chew his leg or some other part of his body.

If this happens, he may develop an infection, which will make him very uncomfortable.

If you think your dog has these issues, contact your vet so that he can recommend solutions.

Skin Infections

The skin of a dog is very sensitive.

It can easily become irritated by things like sunburn, insect bites, fleas, and other pests.

If you’re not careful, this irritation may turn into an infection that spreads throughout the entire body.

A common form of skin infection in dogs is ringworm, or dermatophyte.

This fungus is a parasite that lives on the surface of the skin.

It creates a thick, scaly layer over the infected area, which then develops small bumps or pustules.

The infection can spread quickly through contact with another infected animal, so it’s especially dangerous for puppies.

Ringworms can also affect humans, but most people won’t get sick unless they come into direct contact with the infected dog.

Another type of skin infection is sarcoptic mange, which is caused by mites.

These parasites live under the skin and cause inflammation, hair loss, and itching.

They can also infect other animals (including humans), but you don’t need to worry about this unless you have a pet rabbit, guinea pig, or ferret.

If you notice any unusual behavior in your dog, such as scratching at his paws or head, licking his lips excessively, or chewing on his own feet or tail, it could be a sign of a skin condition.

Contact your vet immediately if you think your dog has these symptoms.

He will likely prescribe a topical ointment or cream to treat the problem.
