Oh geez where to begin. So many of my favorite looking dogs are high-energy and that guarantees I'll never be able to own one.
Most of the pointer group. Viszlas, weims, GSPs english pointers..... God I love how they look and I love their personalities too for the most part, but way too much boingboing for me, and too needy.
I also love Great Danes (natural ears, all the way), dobies (love fawn and red!), also I really like natural ears on dobies--no offense to anyone who has a cropped one. I think pharaoh hounds are gorgeous, and rhodesian ridgebacks--I've always wanted one and may some day, who knows. And for some reason I find Chinese Cresteds (the hairless ones, the powerpuffs don't do it as much for me) really charming. I'm normally not in to small dogs, but I think cresteds are adorable. The only ones of that group I could ever see myself owning would be a RR or dane, but honestly my house is just not big enough. Normally I tell people that house size shouldn't dictate dog size, but with the giant breeds....I think I'd need a bigger house!
