Dizzy eats anything -- anything. He is part Lab, and Labs are the garbage cans of the dog world, or maybe the goats. Dizzy's eaten tin foil just because it once held food.
He also eats grass. Lots of grass, whenever he can get it.
Conventional wisdom says that dogs eat grass to make themselves throw up. Books and vets say you shouldn't let your dog eat grass. It has no food value, it's often infested with mites, and blades of grass have sharp, serrated surfaces that can damage a dog's stomach and intestine linings.
Dizzy seems to be the exception to the rule. He's always eaten grass, and I have never been able to break him of the habit. I've tried everything, from aversion therapy (squirt guns and pennies in a soda can) to supplementing his food with a chlorophyll powder (he wouldn't eat it; I tried it, and it did wonders for my skin). He doesn't throw it up, and it never seems to bother him much.
His vet in California said, "Some dogs are just grazers." I wonder whether Dizzy thinks that he's really a cow.
