Sort of in defense of never liking them much:
If you really don't like the look of a dog (not just eh, whatever, but don't like it) or you just don't much like the breed, then suitable for your lifestyle shouldn't push you into getting one. There are so many breeds and mixes out there that you should be able to find one that suits you perfectly, if not 100% in all ways.
There are many perfectly good breeds (or mixes of those breeds) that might be perfect for me according to all the "factors", but that i will probably never own, either because I really don't like the look, or the dogs, though perfectly nice, don't appeal to me much. I'll actually give pit bulls as an example. I know a lot of them, I like them fine, they are sweet and funny dogs. But I don't want one. I can't really explain why, but I don't. They just aren't "me". Same with a lot of the spaniels, which my father adores. Very nice dogs. But they're tendancy to follow my father everywhere staring at him with sad, adoring eyes actually drives me nuts. As for looks, one of the bullies, the bull terrier, just doesn't appeal to me visually at all. I don't like that head. I'll never like that head. Nothing wrong with it, but I really don't like it.
But you should see the dogs in person first . . . greyhounds are very different in person.
