I only had 1 bull terrier, but he was a real dandy, sombitch weighed 70 pounds and was a sweetheart, liked everyone and everything, except if they wanted to fight, he was ready but would rather play.
Stopped a a shop to pick up some parts one day and he got out and was thirsty I guess, drank some spilled anti freeze I guess and died in pure agony of kidney failure a week later,, not a pretty thing to watch and he was a great dog and have always wanted another.
