Was at a party once and the owner had a dog - a pitbull in fact - and we were kinda playing with it, chucking stuff for it to fetch and wrestling to get it back etc All harmless fun, but I'd never done that before and the strength of this beast was absolutely unbelievable, it wasn't even that big as pitbulls go I guess but I gained a newfound respect for this brutal mass of muscle. There was more strength in its neck than in the entire body of any two people I know. Admittedly that neck was thicker than my body.... but, being attacked by one of those.... it doesn't bear thinking about, was throwing four or five or us around like rag dolls.
