Ok so basically yesterday we got a new dog. He's 3 and a half and he's a GSD/Akita. We already had one bitch, 9 months old and very very playful. So when they met they were playing, no problems it would seem. Today we let them out into the back garden, the 9 month old likes to herd him in, probably guarding her territory. Anyway, then they started playing, running around the garden etc but the new dog started snarling and snapping at the 9 month old. I just wondered if this was normal or something to be worried about? I know it's early days but i'm on edge whenever they go out. He's absolutely fine within the house, he lets her sniff him etc without even a second glance. Just looking for a bit of guidance? Thanks.
