Mutt on steroids!!!
B'liv it or not its a dog!!! The strongest Dog in the World. Working in Russian Army Special Forces.
Origins: The canine shown above isn't "Working in the Russian Army Special Forces," and it probably isn't "The Strongest Dog in the World," but it is a real pooch nonetheless.
The type of dog pictured here is a whippet, described by the American Kennel Club as "an English Greyhound in miniature" and "the fastest domesticated animal of his weight." Specifically, this dog is a "bully whippet," a type of whippet with a genetic mutation that makes it more muscular and faster than standard whippets:
When mutant, muscle-bound puppies started showing up in litters of champion racing whippets, the breeders of the normally sleek dogs invited scientists to take DNA samples at race meets here and across the country. They hoped to find a genetic cause for the condition and a way to purge it from the breed.
It worked. "Bully whippets," as the heavyset dogs are known, turn out to have a genetic mutation that enhances muscle development. And breeders may not want to eliminate the "bully" gene after all. The scientists found that the same mutation that pumps up some whippets makes others among the fastest dogs on the track.
Wendy, the bully whippet in this photograph, lives in Victoria, British Columbia, and is remarkable even for a bully whippet in that she has two mutated copies of the gene and is therefore a "double-muscled" bully whippet who weighs twice as much as a standard whippet. She was the subject of a number of news features in mid-2007, including articles in the New York Times, the UK's Daily Mail, and the Victoria Times Colonist, the latter of which described her thusly:
Wendy is a 27-kilogram rippling mass of muscle. Forget the so-calledsix-pack stomach: Wendy has a 24-pack. And the muscles around her neck are so thick, they look like a lion's ruff.
"People have referred to her as Arnold Schwarzenegger," says doting owner Ingrid Hansen, stroking Wendy's sleek black coat and white chest.
Wendy was recently part of a genetics study done in the U.S. on mutation in the myostatin gene in whippets, which resemble greyhounds in appearance. The National Institute of Health study reported that whippets with one single defective copy of the gene have increased muscle mass that can enhance racing performance in the breed, known for speeds up to 60 kilometres an hour.
But whippets with two mutated copies of the gene become "double-muscled," like Wendy. It has been seen before in one human, and also in mice, cattle and sheep, says the study.
The uber-muscled whippets are called "bullies," not because of their nature — Wendy likes nothing better than a good back scratch and isn't shy about sitting in your lap to ask for one — but because of their size. She's about twice the weight of an average whippet, but with the same height and small narrow head — and
the same size heart and lungs, which means she probably won't live as long as normal whippets.
Additional photographs of Wendy can be viewed in a 2009 Times Colonistphoto gallery.
A research article about the mutation that produces double muscling was published in the PLoS Genetics journal.
