srnity: I don't think..espeacially at 100+ pounds that they should be in a crate for 12 hours at a time..when you go over,are they being walked at least an hour so they can strech their legs and get some excercise? I don't understand WHY people think it is OK to do this to animals instead of just bording them at a reputable place where they could be outside playing and just being dogs.How about if we put THEM in a crate for 12 hours at a time with no food,water,or toys to occupy their time.
