If your dog has compulsive or constant biting, licking, or chewing, it can be a sign of bigger health problems. If your dog is showing signs of skin irritation, you may need to schedule an appointment with a pet dermatology professional. The following are the most common reasons why your dog may be engaging in that compulsive behavior, and what to do about it.

5 Pet Health Conditions Indicated by Scratching, Licking, or Chewing

1. Allergies 

Allergies to food ingredients, medication, or environmental factors such as mold or pollen are common causes of compulsive itching or chewing. Dogs may also be allergic to soap used to wash their bedding or grooming supplies. The best way to investigate a possible allergy is to change food and other products that may be causing the issue, such as dog shampoo or laundry detergent. An allergy test may be needed if simple changes don’t work.

2. Parasites

Parasites such as ticks, fleas, and mites cause your pet to scratch incessantly. You may not be able to see the parasites, but a vet skilled in pet dermatology can help you narrow down the culprit and prescribe medication to repel the parasites. If there is an infestation, wash bedding and toys and vacuum areas frequented by your pet. Other animals in the house will need to be treated, too.

3. Anxiety

Dogs may engage in compulsive behavior if they are anxious or bored. If a veterinary appointment doesn’t indicate a physical cause of the behavior, this might be the answer. Your dog may need more exercise and socialization or calming techniques such as a white noise machine or daily pet sitting. Medication is an option for some dogs but will need to be approved and prescribed by your vet.

4. Hormone Issues

If your dog has bald spots in addition to scratching, they may have a hormonal imbalance. Too much cortisol can create skin conditions and patchy areas in the coat. Blood work may be needed to confirm hormonal imbalance.

5. Pain

Your pup’s compulsive licking can be an indicator of pain. If their attention is focused on their paw, for example, check to see if there is a stone or thorn embedded or if they have a wound. Arthritis pain may also cause self-soothing behavior in the impacted area. A vet who specializes in pet dermatology can rule out common skin issues and help you understand the true cause of the animal’s behavior.
