Here are the things to look for:
1. Is your EB pup active (all day)
2. Will he walk with you (may be 1/4 - 1/2 mile); 2 times a day
3. Does he fart a lot (too much "good" food)
4. When he is active and alert; does he have a "piqued" look. Yes it matters; bullies can be irrationally uninteresting
5. Call and he should come to you (wherever he is)
6. Some puppies grow quick (mine did); they even out; discourage jumping or standing on hind legs
7. Walk the pup!! (most important)
