Does anyone have any tips for training a stubborn puppy to stop biting. I know hes still teething but aside from that, anytime we try to pet him he snaps at us, and if he misses you can here his teeth snap together so we know hes really trying to bite. Sometimes its playful but after a while he gets aggressive and bites harder, snarls his snout, and when he makes contact with his bite he'll flail his head back and forth like you see when dogs attack. We've tried the more aggressive route by standing over him to show dominance, all the way to treat motivation where we'll give him a treat if he let's us pet him or let's us give him love. Hes 8 weeks old. Any tips are welcome. Thank you in advance!
