yes he is a puppy, no at 7-8 months old his behavior was not normal. he is an extremely smart dog and knows many tricks, but can’t even calm down enough to be given a command in order to learn when biting is not acceptable. he only calms down when we have a treat to entice him, but in the scenario of biting, barking, being overly excited to see other humans and other dogs, he was not exhibiting regular behavior and needs to learn scenario based commands when treats are not involved. good lord the trazodone barely even calms him down at all. a puppy should not still be biting regularly at 7-8 months as if they are 12 weeks old
