Nibbling can become problematic when it indicates aggressive behavior and worsens if ignored. For example, when a dog nips at your arms, it may mean it’s being malicious and giving you a warning.
If you just adopted a puppy from a local pet store, it’s normal for it to nibble, bite, or gnaw at you until it’s properly trained.
Since dogs don’t have access to the internet as we do, the only method canines have to investigate and research what they want to know is by using their sense of taste and smell.
Another reason your dog might be nibbling on you is to show other dogs you belong to them.
Nibbling is a behavior dogs perform since they were puppies and bring the habit into adulthood. It’s a coping mechanism to help them calm down when faced with a stressful situation.
