1. Common Culprits Behind Nail Biting in Dogs
The habit of nail biting in dogs can be a sign of several issues. Pinpointing the exact cause is the first step to addressing the problem effectively.
1.1. Overgrown Nails: A Source of Discomfort
Overgrown nails are a very common reason behind nail chewing in dogs. When nails become excessively long, they exert pressure on the paw pads, leading to discomfort.
How to Identify Overgrown Nails:
- Listen for a clicking sound as your dog walks on hard surfaces.
- Observe if the nails are curving or twisting unnaturally.
- Check if the nails extend beyond the paw pads when the dog is standing.
Solutions:
- Regular Trimming: Trim your dog’s nails every two to three weeks.
- Professional Grooming: If you’re uncomfortable doing it yourself, take your dog to a professional groomer or vet.
1.2. Allergies: The Itch That Leads to Chewing
Allergies, whether environmental or food-related, can cause intense itching around the paws and nails, driving your dog to chew for relief.
