This will not only help your puppy learn that people and petting are wonderful, but will also keep her mouth busy while she's being petted. Alternate which hand does the petting and which one has the chew bone. At first, you may need to pet or scratch your puppy for short periods of time, since the longer she's petted, the more likely she is to get excited and start to nip. Chewing Never discipline or punish your puppy after the fact. If you discover a chewed item even minutes after he's chewed it, you're too late to administer a correction.
Animals associate punishment with what they're doing at the time they're being punished.
Punishment after the fact will not only fail to eliminate the undesirable behavior, but could provoke other undesirable behaviors, as well. Rough Play Attempts to tap, slap or hit your puppy in the face for nipping or jumping up are almost guaranteed to backfire. She could become afraid of you and refuse to come to you or approach you at all. She could respond in a defensive manner and attempt to bite you to defend herself. She could interpret a mild slap as an invitation to play, causing her to become more excited and even more likely to nip.
