Hey all, We are new members. We have a lil Border Collie, who is 14 weeks old. This is a new experience for us and to make things harder we have two Tonkinese cats (1-year-old). Along with the persistent biting, we are finding it really challenging getting him to rest in the living room when we know he is tired. We'll play with him or come back from a walk, then do a restful yet stimulating activity like chewing a tripe stick or find the treats, but after it's done, he'll just go on the crazy jumping, biting frenzy (that really hurts). We've had a wonderful puppy trainer help us, who seems to work her magic on him at the time but as soon as she's gone... the crazy mode begins again and we put in the kitchen to allow him to sleep. We've run out of ideas and not knowing where to go next. We've tried all the tricks in the book as well as tips we've seen in the super useful forum.
