My Dog Is Constantly Scratching And Biting Himself: What Are The Probable Causes?

You might be getting worried seeing your dog scratch and bite themselves intensely every day. They might be chewing their own tail or licking their paws constantly.  

It is uncomfortable for them as well. You may be wondering why my dog is constantly scratching and biting himself. Compulsive licking, scratching, and chewing are common in dogs, but for different reasons.  

These can turn out to be harmful as well. This can cause dog hot spots from the persistent scratching and biting. However, this can occur anywhere in the body; they are most commonly found on the hips, chest, and head.  

My Dog Is Constantly Scratching And Biting Himself: What Could Be The Causes?

Dogs can scratch, chew, or lick for various reasons. However, some of the common causes include parasite infestations, allergies, and boredom.  

1. Parasites 

This is one of the most common causes behind your dog scratching and biting themselves. Mites, fleas, and ticks are some of the reasons behind compulsive dog chewing and licking.  

Even though you can see ticks with the naked eye, fleas are something that is very difficult to identify until there is a huge infestation. Mites are microscopic as well. So, you need to take them to a vet even if you cannot see anything with your naked eye, just to be on the safe side. 

2. Allergies 

My dog is constantly scratching and biting himself. Why? It could be some environmental trigger, like pollen and mold, or food allergies.  

Moreover, they can develop a skin condition known as contact dermatitis when they come in contact with substances like soap or pesticides. 

3. Pain 

Another reason why they might be doing this compulsively would be because they are in physical discomfort. For example, if you find your dog biting their paw excessively, it could be because there is something stuck to their foot pad.  

Moreover, this could occur due to orthopedic problems, such as hip dysplasia and arthritis. 

4. Anxiety Or Boredom 

Dog anxiety could be a reason behind their compulsive behavior. Like us humans, they also bite their nails or scratch their coats. Their physical behavior could be a response to their psychological trauma. 

Moreover, dogs also often develop obsessive-compulsive disorder or OCD. They can manifest these behaviors and can often cause severe damage. 

5. Dry Skin 

Dry skin can happen from different factors, such as fatty acid deficiencies and weather changes. This scratching and licking could be their way to ease the discomfort. 

6. Hormonal Imbalances 

If the dog is putting out too much cortisol or not producing enough thyroid, there are chances for superficial skin infections. You will start to see bald spots, and they will lick and scratch themselves as if they are getting an allergic reaction from something.   

How To Treat This Compulsive Behavior?

There are numerous reasons why dogs scratch and chew. So, to treat them effectively, you need to know the exact reason behind this compulsive behavior. You must take them to a vet as soon as you notice it.  

The vet will determine the exact cause and recommend the most suitable treatment plan. The treatment depends on the cause, and here are some of the common treatment plans they suggest. 

1. Eliminating Parasites 

If your fur baby is affected by ticks or other fleas, the vet will recommend some products to get rid of those parasites. Moreover, if this behavior is caused by fleas, ensure that you wash their bed and vacuum the carpets as well. 

Moreover, change the covers of the furniture regularly, so there is very little chance of infestation. Also, if you have multiple pets at home, get them checked by a vet as well. 

2. Using Medication 

If this is happening because of some underlying conditions, then your vet might suggest some medications to treat this problem, which will ultimately help them with their licking and scratching. 

 Moreover, vets often recommend some tropical antibiotics, anti-itch products, or steroids to treat skin infections or hot spots. 

3. Changing Foods 

If this itching and licking are happening because of some food allergies, then identifying those elements and eliminating them can make a lot of difference. This might come as a surprise to you, but grains are often a cause of food allergies. 

Animal protein often causes allergies in most pets. Your vet might come up with a special diet if that is the issue. Moreover, adding some dog food for itchy skin or supplements rich in fatty acids can help them get rid of their skin issues as well. 

4. Addressing Boredom/Anxiety 

Sometimes, a dog develops this compulsive licking, chewing, or biting as a response to inadequate stimulation, fear, or stress. To reduce the chances of that, you need to get them enough exercise, love, and attention. 

Moreover, you can train them to chew on bones or toys to relieve stress and replace their inappropriate licking or chewing behavior. 

5. Preventing The Behavior 

Compulsive behavior can cause serious damage to dogs and can severely affect their quality of life. You must try everything to prevent this chewing and biting. 

Some people try using bitter sprays on their bodies to discourage licking, or make them wear a special collar, so that they cannot access the hot spots. Also, keep them close to you when you are at home so that you can monitor their behavior.
