Dog Nibbles On Everything. Thankfully, impulse control can be taught at any age although it is easier as a puppy. The best way to describe a love nibble is to picture your arm like an ear of corn and your dog is eating that ear of corn, which is your arm, if you’ve forgotten.
When your dog nibbles your hand or ears, it is a sign of affection. He’s given me love nibbles since as far back as i can remember and he usually gives them when he’s excited, like when i come home from work. Dogs typically nibble on other dogs and humans as a way to play with them, to explore objects around them, to show dog mouthing affection, and during the teething phase of puppyhood.
