Hi got a 12m old lab. He's a major mouther!! Started as soon as he came to live with us at 8week and has never got better. We followed standard advice of ignore move away basically don't give it attention but because of the amount he does it it was really challenging. We tried a yelp but that didn't help. Consistently for about 6 months now we move hands away and say get your toy, which he does but the biting has not lessened. He will also accidentally bite if being hand fed, during play, he bites if we are doing something he's unhappy with ie brushing (although treats do help for distraction) and he will occasionally jump up and bit our arms if he's excited/frustrated. Anyone stopped an older biter?
