5 Tips to Stop Your Puppy from Biting
Most puppies chew because they are teething. Give your dog chew toys that are acceptable for him like rubber kongs filled with peanut butter, ice cubes, elk antlers or nylabones.
Replace your hand with an appropriate chew toy, then praise the puppy for chewing the toy.
Put a leash on your puppy in the house so that when he starts to nip, you can give him a leash and collar correction. Over time he will learn that nipping is an unacceptable behaviour.
Use a command like “leave it” in a firm voice then praise your puppy when he stops biting.
Distract your puppy by playing fetch with him
