Mutts are more likely not to be imbred. And are cheeper!! lol j/k. The store i bought Jo from (YES ITS CLOSING!!) invent breeds (like a mutt) and put the 2 parents together to form a new breed, and yes, they charge 400 dollars for it....Breed doesn't really matter to me, I just feel in love with Jo when I held her, annd I couldn't afford a purebred when mutts are just as good I think no diff really only one has papers
