Milly and Sasha have had the tendancy of playing a little rough when it comes to fetching a Kong. Well this last time it went too far. Sasha got a lock on Milly's shoulders and would not release, well being a big dummy I tried to pull them apart and Sasha locked on to my calf giving me a very deep puncture wound (yes I was treated and going to be OK). Play time is the only time that Sasha gets in the least bit aggressive. So, guess I am going to have to quit playing fetch with both of them, any other ideas to stop toy aggression?
