For isla49: I understand that you may not think Sch. is for molossers, but can you tell me what do you do with your dog(s)? Sch. is not only fun for the dogs, because I live in DC and there is no hunting, or chasing wild animals in the city. So what do you do to know that your dog will perform under pressure, or do you think because your dog is in its backyard barking at people or animals that it is ready for action? I just want to know how do people gauge their dogs on being dogs and not 100+lbs kitty cats. I also believe that almost any type of dog can be trained for almost anything, with the right trainer and handler. I do not believe molossers are not of high 'trainiblity', it has something to do more with weak handling skills in my honest opinion!
