We're using a training line with Casper as he is a biter especially with my nephew and my sister's shih tzu

We were advised by the lady who will be doing our puppy classes who is a behaviour advisor as well as a trainer to make a loud noise (we use 'no' or 'arrr') and to take him away from the situation (we take him up the hallway) and since being on the line his biting has improved MASSIVELY and we're only having to remind him occasionally now rather than 24/7
Good luck....feel free to PM me if you need any advice
