I’m going to disagree with the person who said to leave him alone when he bites. If he hasn’t been socialized properly that may be rewarding the bad behavior. You do need to build trust with him and keep working with him.
Give him treats and lots of praise as you introduce him to scary things, take it slow.
Make sure you’re not pulling his hair when you are brushing.
Puppies make a high pitched yip to tell each other they are being hurt. You could try this (with your ouch). If he’s being aggressive he might not care.
Be gentle and patient. He’s a bit old to only be starting out, so it might take extra time.
Meanwhile, look into ways to handle him to avoid his teeth. There’s utube video about how to groom an aggressive dog where he shows ways to hold the dog so it can’t reach you.
Listen to your trainer, but follow your own instincts, too. Good Luck. |
