Then why is there a Greyhound Rescue branch in nearly every county in England?
I'm not saying you personally are a cruel dog owner, but there are many whose greyhounds are not well treated, and have to be homed by these charities.
Believe me, I've seen the most distressing photos of some of these animals, pitifully thin, suffering from old injuries, only able to walk slowly. I know several members of the Norfolk Greyhound Rescue, and I don't imagine they make all this up!

'People like you...' ? There's only one of me akenaton. I'm not at the head of an entire army of Senoufous!
