Not dissing Gabe but, IMHO, there is a certain 'shape' that dog breeds should adhere to. Yes, I know that you can breed a really funny looking bug-eyed mutant dog that's really unhealthy and lives a short, shitty life while your friends get to laugh at it and stuff. I'm not into that stuff.
Basically the healthiest dog breeds tend to be mixed breeds that are somewhat hunting oriented and basically are shaped like a wolf with that snout and ears and good fur, none of this lapdog crap, or huge dogs with hip problems etc.
