I definitely love the looks of the majority of pure breds. That being said, I really can't in good conscience support the continued in-breeding of dogs for the sake of my vanity. I mean, I know that there are many good and respected breeders, but I feel that we're kind of ruining things for the dogs from an evolutionary and genetic standpoint. Pure breds are gorgeous, but so incredibly susceptible to diseases and maladies that a mutt would otherwise be fine with.
Mutts have a certain appeal to them, some of the more scrambled varieties are barely indentifiable, which is kind of cool as they look a part of so many different breeds. That, combined with the fact that they can be much healthier leads me to want a mutt, despite how pretty pure breds can be.
