Like in humans, airborne allergens often cause intense itchiness. Dogs then lick and chew their paws to relieve the atopy itchies. Dogs may also engage in nail biting while trying to cope with itch-inducing allergies. These behaviors can also be triggered by other allergic reactions, such as those from food allergies.
One commonly shared behavior by both dogs and their owners is nail-biting. In humans, it is usually associated with anxiety or stress, boredom, and most recently an individual's personality.
Why Do Dogs Bite Their Nails? Dogs can bite their nails as part of the grooming process, especially if their nails are very long and uncomfortable. However, they tend to bite more for medical reasons, like allergies, a skin condition or infection, or even anxiety.
Sometimes dogs will lick their feet or joints because they are stiff and sore, just as we might rub a sore patch. Boredom and stress can also cause your dog to lick and bite their front paws out of frustration which can then become habit.
If you think your dog may have a nail injury, it's important to have them seen by your veterinarian right away. These injuries are known to get infected quickly, and can result in severe pain for your pup. If infections go untreated, they can be harmful to the overall health of your dog, or even fatal.
When you see your pup biting or chewing on their nails, it's usually indicative of something bothering them around their paws. If this becomes a chronic problem, it could be a sign of something brewing. Anytime your dog has odd behavior, it should be something you should keep an eye out for.
Separation anxiety can cause nail-biting in certain dogs. If you've left your dog alone all day while you're gone, they could be stressed. An allergy can sometimes be the cause of a dog gnawing its nails. Some allergens from the outside may have stuck themselves to your dog's paw.

Allergies/dermatitis: One of the most common causes of dogs biting their paws is an environmental allergen or food allergy due to the protein in the diet. Just like humans, dogs can have an allergic reaction to different allergens present in the air, on surfaces, in furniture, or on plants.
Your Dog Has a Health or Behavioral Problem Speak to your veterinarian if you can't figure out why your dog is excessively licking or biting their paws. Your vet should be able to help you pinpoint what's going on and if there's a health or behavioral issue they can advise you on how to manage it.
A: Doctors classify chronic nail biting as a type of obsessive-compulsive disorder since the person has difficulty stopping. People often want to stop and make multiple attempts to quit without success. People with onychophagia cannot stop the behavior on their own, so it's not effective to tell a loved one to stop.
The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, categorizes chronic nail biting as other specified obsessive-compulsive disorder (OCD), classified in the same group as compulsive lip biting, nose picking, and hair pulling (American Psychiatric Association, 2013).
