We have a small Standard, which my boys absolutely love. He's about 11, so not nearly as spry as he used to be, but still a wonderful pet, especially with the limited attention we have had to spare over the last few years when the boys were infants. Now that we spend more time with him, his age is noticeable but he used to be a great hiking companion.
I just feel like a) he's by far the most stubborn dog I've ever worked with - smart enough to know exactly what I want, and, umm, independently minded enough not to give a rat's ass; and b) I grew up with #75 mutts of all makes and models, did a lot of rescue work in Costa Rica with street mutts - I can't shake the conviction that a dog that you can't wrassle with ain't much of a dog at all... With all the options out there, I don't think I'll do a Schnauzer again.
