I have an 8 month old puppy and he won’t stop biting at me and my family. We were thinking it’s just teething and it would be just a faze. However, the biting keeps getting more aggressive and starting to leave bruises too. This behaviour started a 2-3 weeks ago and I’m struggling to find what could be triggering it. The only change I could think of is that we got him neutered 3 weeks ago. My family and I have tried time outs, saying “No/Leave it” and walking into another room, redirecting attention with toys and rewarding with treats when he stops biting. We take him on 30-40 minute walks 2-3 times a day thinking it would burn off any excess energy. We’re at our wits end and any tips or advice is greatly appreciated.
