I think you figured out part of the problem. Ideally, your puppy would have stayed with her mom until twelve weeks old. Puppies learn very important lessons from their mom and littermates during those weeks, including bite inhibition.
It does sound like your puppy may have a temperament problem, though. I think you are wise to get her evaluated by a behaviorist asap. Hopefully by dealing with the problem now, you can avoid serious problems later on. |
