Fight :(

[Discoetheque]

I agree with those who are saying not to discount a dog based on size. For one, Cairn terriers are not a dog I would describe necessarily as "small" (short, maybe, but they're pretty broad, like a smaller-medium), particularly in comparison to a 6m Shepherd. We don't know how big either of the dogs are, either, compared to one another. Not to mention there is a difference between a bright-eyed, idealistic puppy and a seasoned veteran (again, we don't know how old the other dog is, either) Cairns are solid and heavy, tenacious and every single one I've ever met (and there is a fair number) has had an attitude, like terriers should. To say that dog was of no real threat because it's just a terrier and is smaller is dangerous thinking in and of itself that is of no real service to anyone, human or dog.

I'm glad you were able to get Charlie and the other dog separated. Like others have said: make sure all his interactions from now on are with known, friendly dogs. Maximize his chances to grow up unscathed from this incident.
