I've been teaching my pup about proper bite force. They say that if your pup bites a bit too hard, say ouch. The only thing is, for me, saying ouch is the same thing as a squeaker on a squeaky toy- it doesn't work. It just makes her even more 'bitey'. Any tips? When I redirect her or walk away, it usually works pretty well. Sometimes, she'll just try to follow me and nip at my heels.
