Bite inhibition refers to a dog's ability to control its natural instinct to bite or chew. It is an essential trait for dogs to have, as it helps them interact with humans and other animals without causing harm. Dogs that lack bite inhibition may be more likely to nip or bite during play or when they are excited, which can lead to injury or discomfort for their human companions. Training and socialization are important factors in developing a dog's bite inhibition, as it helps them learn appropriate ways to interact with others.
