In Germany and France it is quite common. That's where a lot of our retired horses go. I haven't heard of horses being used for food in the US, but personally I don't see it as any less appealing than other large meaty animals.
Dogs, on the other hand...
Quite a bit of horse meat is consumed in Japan where they enjoy it raw.
I just got a new Vietnamese cook book, "101 ways to wok your dog".
I think onle barbarians eat dogs, horses and cats. Their close association with human beings over millenia of domestication as pets, companions, comrads in arms or hunting pals should negate their consideration for food.
Maybe the degenerate French would find dog stew or filet of mustang palatable, but I certainly don't.
ISn't Bo Derek a conservative Republican, or do I have her mixed up with some oother Hollywood blonde who is????
