Defanantly both, mutts are loyal and purebreds are gorgeous, I've owned both and love both as much as the other. At the moment I own a purebred female Husky called Zeth, She's beautiful
i would have to say for the moment purebreeds i love the most, just because simply, my border terrier phoenix is one!....when i was told i was allowed a dog i went with purebreeds straight away.....
Not to say i dont love the mutts, my other halfs dog is a border collie/lab cross and boy is he a little (well no so much little) star....
I have a purebred weimaraner, she is so clever it scares me sometimes as she is so sneaky!!! I suppose i'd have to say purebred for looks, but then again some crossbreds look so cute!!! I saw the cutest jack russel x daschund the other day, and i'm not really a fan of ankle biters!!!! My weimeraner is sooooooooooo cute!
I love both purebred dogs and mutts because at the end of the day they are all still canines. There is much more to say about this topic as far as the opinion of many I see that say purebreds being less intelligent, less managable, and unhealthy but I've fought this battle so much with the intent of educating and coming back the result of annoying that I'm not even going to try.
