Razors Edge dogs were started from a dog named, "Throwin' Knuckles". He was an old Ruffian/X-Pert cross. A white dog with Blue Cow Patches on him. He, himself, wasn't a horrible looking animal. It's the animals they produced down from his offspring that went to shit. The stuff you own Canismajor is along the same lines as Razors Edge bloodlines, just not AS shitty of a version. Now, that said.. Sierra Nevada Kennels is nothing more than a glorified peddler. She believes, because she shows those mutts in the UKC (which is a joke in it's own) they are worth thousands of dollars for a puppy... She is a SELL FIRST breeder, which is NO GO in our book.
