Staring Down Superdog.

You wouldn’t know it by looking at her, but Wendy (yes, this dog is a she) is friendly and “likes nothing better than a good back scratch and isn’t shy about sitting in your lap to ask for one”. The Whippet’s herculean appearance comes from two gene defects which cause a condition called “double muscling”, which can occur in any animal species. Link
There’s even an unnamed German boy running around with this genetic defect (the only recorded human case), who as a toddler had the strength of some adults.
