The class had a lot of Rots, not those belonging to the instructor. They are fine dogs in the right atmosphere. If you need personal protection, then I would suggest a Rot. But, not allowing them off-lead in the class for fear of them tearing into another dog or ripping someone's arm off is simply crazy. Those dogs should be put down, because they are obviously out of everyone's control.

I bet if you had a class full of dogs under 15 lbs you would have had the same reaction. Dogs will be dogs.
