I have read over and over not to play tug of war games with dogs because it encourages them to pit there mouths against us and might lead to aggression issue later. I didn't know this when raising my sheltie, but have to say i have never, ever had any issues of the sort with him. We still play :blushccasionally. I can't decide if i should allow this play with Dixie, or not. She wants to do it. Anyone play TOW with their maltese? Any problems from doing so?
