Fish :D is my stafford's favourite. Whole fish after fishing trips, fish skin, fish guts , tinned fish of any kind. I stick to less salty kinds ie no anchovies (altho he has been known to sneak pizza crusts with anchovies smeared all over them).
Krash actually goes fishing at the beach... he will spend hours rounding up bait fish in rock pools, when he catches them he flicks them out onto the rocks (we have to find them and put them back in the water...they seem ok, he uses his lips instead of his teeth...how bizarre!)
I think prawns etc have cholesterol...can dogs have cholesterol probs? I guess they'd never have too many prawns or crayfish though...doh! too many $$$
