Hi, I'm new to the forum and to puppy owning. We have had our little collie cross puppy for a week. He's 14 weeks old and the last we got him from, was struggling in her flat with his high energy. He's very bitey and nothing seems to be working. We really don't want to rehome him again but have children and its really getting us down. Please help with tips on how to get him to stop biting us.
