Loki (AB 6.5 months old) has gotten along wonderfully with every dog he has ever met. He gets so excited and all he wants to do is play. We take him to play groups and he goes to doggy daycare every week and he has never shown any signs of aggression. What I'm wondering is, whether or not this will ever change. Do ABs typically get more DA as they get older or is a friendly dog a friendly dog?
