1. The Muzzle Bite
When two dogs play together and one seems to bite the other’s muzzle, people can sometimes be startled by this behavior. However, you really don’t need to worry about this. It is a social interaction that was passed down from their wolf lineage. The pups are merely affirming their friendship; the one being bitten is feeling a bit insecure, so this is a way for the dogs to communicate the solidity of their relationship.
We usually see this behavior from two dogs that know each other well, but we sometimes observe insecure dogs asking their people to do it as well. If you see your pooch come up to you and puff up its nose, just gentry grasp it around the muzzle to let it know that you care about it. They’ll be delighted by the gesture.
