Bully Whippet
The Bully Whippet was created by a genetic mutation. While breeders would normally cull any genetic mutations, this actually made these dogs faster at racing and was continued to be used in breeding. When Racing Whippet puppies started showing signed of mutation and an extraordinary amount of muscle mass, The breeders of the normally slim dog contacted scientists for DNA samples. Their goal was to find the cause of this mutation and purge it from the breed. There was only one drawback from culling this gene, it actually worked to the dog’s advantage. These heavy set dogs were known as “Bully Whippets”. It turns out, that the breeders might not want to get rid of the “Bully” gene after all. The same mutation that created the muscles also help them on the race track. This genetic mutation is know as Myostatin. These whippets are sometimes referred to as Bully Myostatin Whippets. While these dogs look far from normal, they are actually perfectly healthy canines.
