OMG, the best, and by the best, i mean THE WORST, hahaha, There is a guy in our area who breeds EVERYTHING to shihtzus! any small dog, he will buy and breed to it, and sell them for 700-1000$. i was working in my local pet store last year and he came in talking about his new breed the Bull Shit... Well Ok, i was curious... what did u breed to get that? well he says... a bull terrier and a shihtzu... First of all. I have the only bull terriers in town. and i know this for a fact... So he didnt use my bullies... so i questioned where he got his bullie... and the color etc. Hes like, oh well its normally called a boston bull terrier... WHAT IS THAT? He totally meant a boston terrier. Like, he doesnt even know his breeds! aaahhhhh! i was so mad.
