I kid you not... I once got taken down by a billy-goat that had the same body build that that pooch.
Blind-sided no less... Ever see those foot-ball follies where a player gets tossen into the air and absolutely thrown for a complete loop?
That was me.
Funny now that I think about it, but at the time all I could do was just get up like nothing had happened and slowly back out of the fence while keeping an eye-out on him.
Hell, after that billy-goat-from-hell episode, I'll never turn my back on a goat again...
As far as dogs go, the only bite I've had has been from a "Oh she has never bitten anyone" Cocker-Spaniel that was foaming at the mouth. Ripped my good jeans too.
Those big/ bad muscular pooches... I've never had a problem with. Most just want someone to play with'em.
