There are probably more breeds that I wouldn't have then what I would have.
Top on my list are labs- I just haven't had good experiences with them. All I have met have been hyper, nippy, and very aggressive. I have been told that this is not supposed to be the norm.
Then, poodles. I just don't like the way they look. My mom thinks poodles are great- smart, don't shed, etc.
Hounds- the smell, and the difficulty in training. Although, I think basset hounds are SO CUTE! I also love the look of blood hounds.
Other then that, I'm fairly game for most breeds.
I love the look of bull terriers, malamutes, and pit bulls. Ironically, most of the pit bulls I've met have been friendlier then the labs.
