Our puppy has taken to mouthing my younger son. Pup is 5 months old - never really nipped at all (so never had to teach her to stop doing it before). But at 5 months is quite strong so this needs to stop.
I get him to stand still, and say no. But when you are 8 with a dog round your ankle this is hard. She only does it to him, no one else. She isn’t really biting, just playing with him like he’s another puppy.
Anyone got any more ideas? He loves the dog and is very good with her. She was bought party because of his sustained campaign to have one! But it is really beginning to upset him that he is only one she does this too.
