My JRT puppy is 5 months old now and for the most part is pretty easy going dog. I have 3 children and he is woken up at 6am, played with and stimulated nearly all day and he is well exercised.
He is pretty obedient and picks up things quickly and he does know he is at the bottom of the pecking order.
The only 'problem' is that he is very grumpy in the evenings and growls at the kids. He doesn't do anything other than growl. As soon as he has had enough he gets sent to bed which is in a crate in my utility room but he will then growl if you go in the room (he does get told to be quite) but the fridge and downstairs loo are in there so we do need access.
Is the best thing just to tell him to be quiet and ignore him?
