Wally is doing his best at BRLA.  He walks fine in a pack but does not give it up for any other dogs.  We like tolerance but we would feel better if he interacted with others (rather than just tolerating) to ensure a match.  It could totally be kennel stress and Wally not wanting to “give it up” before he knows he is home before he totally bonds with another dog.  In the meantime, he shows no aggression, he is fantastic on a leash and he could be a wonderful addition to your family if you have some basic dog skills.
