Puppy Blunders & Problems?

If you are telling me that your puppy is understanding and doing all those things you listed he is doing wonderful. It sounds like your expecting alot of your pup when is still young. I have a puppy the same age and he does do alot of what yours can do. He does respond outside to his name when i make a bif fuss and have a yummy treat or a toy or ball. But he's still yound and there senses are excited and taking in the excitement of outside. It sounds like you put alot of time in training him as i do my puppy. Dont get frustated just keep calling him and enticing him with whatever works.
