Btw, the owner of the pitbull is white.
And Wendy the whippet did NOT have gene therapy. There are pretty much three types of whippets, the reg ones, then the muscular ones, and the ones that lack myostatin control. Most breeders tend to have the third as pups put to sleep. These dogs also all have a short shot snout, an overbite if you will.
I forgot the terminology for what the three levels are called but once again, people run with what is claimed in the popular media, and go off of that. When pups like Wendy have been born before "gene therapy"
Just like the Belgian Blue bulls, which existed well before steriods and gene doping.
