I have two Miniature Schnauzers -- we've had them for nearly 10 years now. The dogs are literally falling apart. For the last 5 years or so, they have had bad skin problems with the "schnauzer bumps". They are almost like cysts .5" in diameter that raise up all over their back. Their teeth are okay at this point. My youngest (she is 9 years old) has major skin problems (she sweats like you wouldn't believe, and smells terrible). Her hair is falling out (she is looking like a naked dog) and the skin on her neck is dry/craked. The other one (the eldest) now has three very large tumors (one on each side of her body, and one on her chest).
HOWEVER! They have been the most awesome and loyal dogs I've ever had the chance to associate with. Very very smart, but they do like to bark. They are "mousers" and have caught all manner of mice, rats, squirrels, birds over the years. Very playable, very obedient. Don't really shed, don't have a "doggy" smell. I love my girls, they are so intelligent. I'll be sad to see them go (probably soon!)...
