A Firm "NO" When Training A Puppy?My 7 week old shih tzu/yorkshire likes to "talk back" when being told no. When he is doing something like digging into the couch or chewing things we don't want him to chew on and we gently push him away from it and firmly tell him no he turns around, growls, and tries to bite. We pick him up and, again, tell him firmly. He will wiggle and try again and then, after another firm no, he usually tries to lick, almost like to say sorry. Is this somewhat normal and are we handling it the right way? Your help on the last question was greatly appreciated.
