Well, firstly, a schnauzer has a terrier heritage just like a so-called "pitbull" and terriers by nature have an inclination not to back down. Secondly all terriers, as with other dogs, must be socialized and trained, and most people hating so-called PBTs here don't understand what is meant by those words.
So-called PBTs need constant management; neglect one to languish all day in a small kennel with no exercise, chain one, let it stray unleashed and you'll have a wreck on your hands. Treat it with respect in a loving home around people and other pets the majority of the time he comes to believe that are his possessions (and patiently putting up with the torn couch pillows that he believes are his toys) exercise him thoroughly every day, correct his bad manners when necessary, and you'll have a great dog.
Now, I am not going to tell you that there aren't "redzone" dogs that must be euthanized (just as there are mental misfits among human kind, there ARE indeed mental dog cases), and I'm not going to tell you that the training of a so-called PBT is easy because they are extremely thicknecked and hardheaded. But I am going to tell you that they can be made into great pets and family dogs.
By the way mini-schnauzers were lumped into the terrier category because they didn't know what to do with them, but in fact they were descended from standard schnauzers - affenpinchers - poodles, none of which are terriers.
Yeah, I was surprised too. Good girl my Penny, smart-sweet-clean-loyal and quite the hunter.
Ooops, running late, gotta run, good talking to ya.
Happy Tea Party day to all.
Some schnauzers, if not trained, can most definitely be a danger to people. Actually, when trained, they can be used as police dogs (and are used by the Europeans in such work).
