This may well be the craziest looking dog you will ever see in your life. There are plenty of examples of extremely tall dogs or extremely fat dogs, but have you ever seen a dog that looks completely 'roided out? Meet Wendy, a four year old whippet from Canada. The Daily Mail explains exactly why Wendy looks so huge:
She was born with a genetic defect which has left her looking like the Incredible Hulk of Hounds.
While her head, heart, lungs and legs are the size of those of a normal whippet, her gene defect means she is "double muscled".
She weighs 4st4lb - twice as much as she should - and has bulging neck muscles, burly shoulders and haunches like a baboon. And unlike ordinary whippets known for their lithe and narrow frame, this four-year-old pedigree doesn't just have a sixpack stomach, she has a 24-pack."
For reference, here is Wendy next to a normal sized whippet;
So who knows, maybe Barry Bonds really hasn't been taking performance enhancers and just has a strange genetic disorder that doubles his muscle mass over time. But....probably not.
