While there are individual dogs of almost every breed that I like, there are certain breeds that generally just set my teeth on edge for very different reasons. The top three are easily labs, standard poodles, and mini schnauzers. Labs because of the temperment I see in them around here - I don't like out-of-control, in your face, panting type dogs, and that is what we seem to have in Vermont. I've met a couple really nice ones, but the odds aren't in their favor. Standard poodles just weird me out - not really the way they look or act, but they move in such a bizarre way. Mini Schnauzers because I have yet to meet one that isn't a compulsive barker, and I have a very low tolerance for barking.
There are a lot of breeds that I like but will never own - all of the nordic breeds, most toys and terriers, the guardian breeds, scenthounds...some really cool dogs, but not right for me.
