6 Common Reasons Why Your Dog Is Chewing His Nails

It’s normal for dogs to chew on their nails as part of their grooming routine. However, when this behavior becomes chronic, it often signals that something is wrong or bothering your pup. The underlying cause can range from a simple issue to a more complex behavioral pattern.

Below are six common reasons why your dog might be chewing their nails, along with some guidance on how to address each situation.

1. Overgrown Nails

One of the most straightforward reasons for nail chewing is that your dog's nails are too long. When nails grow excessively, they can become uncomfortable and even painful, prompting your dog to chew them off. Regular nail trimming is essential for dogs.

 If you're unsure how to trim your dog's nails correctly, it's best to take them to a professional groomer. While some dogs' nails wear down naturally through regular walking on hard surfaces, others may need more frequent attention to prevent overgrowth.

2. Broken Nails

Broken nails can be a significant source of discomfort for dogs. Sometimes, there is a break in the nail that is not immediately visible as it can sometimes happen at the base of the nail where it attaches to the skin. This can cause pain and irritation, leading your dog to chew and lick the affected nail persistently.

Even though broken nails might eventually come off on their own, it's crucial not to let the situation go untreated as it can lead to infection. If you suspect your pup has a broken nail, it’s best to consult your veterinarian for proper treatment to prevent further complications.

3. Allergies to Outdoor Allergens

Environmental allergens such as grass, pollen, or even certain foods can make your dog itchy. This itchiness often extends to their paws, causing them to chew on their nails to alleviate the discomfort. Allergic reactions can lead to inflammation and irritation in the paws, driving your dog to chew as a way to cope with the itch.

If you notice your dog frequently chewing their nails along with other symptoms like scratching, sneezing, or red skin, they might be suffering from allergies. Your vet can recommend treatments, which might include changes in diet, antihistamines, or other allergy management strategies.

 4. Nail Infections

Nail bed infections, that tend to be fungal, can be another reason for nail chewing. Such infections might occur if a nail is injured, and the wound becomes exposed. This can lead to an itchy, painful infection that your dog tries to soothe by chewing.

If you suspect an infection, it's important to take your dog to the vet. Treatment typically involves antibiotics or antifungal medications to clear the infection and alleviate your dog's discomfort.

 5. Anxiety or Stress

Anxiety is a common issue in dogs and can manifest in various ways, including nail chewing. Dogs suffering from separation anxiety, changes in their environment, or other stressors might chew their nails as a self-soothing behavior.

Signs of anxiety in dogs include excessive barking, destructive behavior, and inappropriate defecation in the house. Addressing anxiety might involve behavioral training, increased physical activity, or in some cases, medication prescribed by your vet. It can also be helpful to create a calm and secure environment for your pup which can help to reduce your dog's stress levels.

 6. Boredom

Boredom is another common cause of destructive behaviors like nail chewing. Dogs need ample mental and physical stimulation to stay happy and healthy. Without enough exercise, playtime, or interaction, a dog might resort to chewing their nails out of sheer boredom.

If you provide a variety of toys, engage in regular play sessions, and incorporating training exercises can help keep your dog mentally and physically stimulated. If direct interaction isn't always possible, especially if you’re away all day working, you might consider interactive toys or puzzle feeders to keep your dog occupied.

When It’s Necessary to Go to the Vet

If your dog continues to chew his or her nails despite grooming and addressing potential allergens or boredom, it's time to see your vet. Your vet will conduct a thorough examination that can either rule out or address medical issues such as infections or a more serious underlying condition.

If your vet doesn’t find any medical cause for the nail chewing, the behavior is likely rooted in anxiety or some other psychological factor which may require a different approach, such as behavioral therapy or environmental modifications.

By understanding the reason(s) behind your dog's nail chewing and taking the appropriate steps, you can help ensure that your furry friend remains comfortable, healthy, and happy.
