My little 9 week old border collie has been chewing the couch (and the coffee table, hall stand and cupboard). Every time I catch her I pull her away from it, and give her something else to chew on. She has every chew toy imaginable. Rubber bones, rawhide bones, balls, soft toys, hard cardboard tubes, soft cardboard tubes....etc. But she always goes back to the couch! Very hard trying to do this no punishment training. My old dog I would have pulled her away and held her down until she calmed down. She learnt very quickly not to chew. But I don't think that kind of training has the best outcome with my relationship with my dog/puppy in the end.
