Nipping refers to a behavior often seen in animals, particularly in young mammals like puppies. It involves gently biting or mouthing, which is a natural way for them to explore their environment and interact with their littermates. This behavior helps them develop social skills and learn bite inhibition, which is important for their future interactions with other animals and humans. In the context of dog training, nipping can sometimes become problematic if it escalates or is directed towards people. Owners are encouraged to redirect this behavior through positive reinforcement techniques, teaching their pets appropriate ways to play without using their teeth.
