I think dogs just like stinky stuff. I had a dog who would roll all over a carcass if he found one.

Jjust make sure to keep your DOGS wormed, as well as your horses. all horses will carry some sort of intestinal parasite despite worming...And it can be passed out through their feces. So just be careful, and make sure your dogs are routinely wormed- With something that will take care of hookworm, roundworm, and tapeworms. You may have to buy some from your veterinarian, but Wal-Mart or some other stores can carry it too. =) Just gotta find it.

They eat grass also some type of Vitamins in it also found of horses hooves too very good for them

If I was hungry enough I'd eat horse manure.
