Why Wont My Dog Eat Or Drink But He Will Eat Grass And He Keeps Throwing Up?

I have had this problem with my dogs in the past, he has a stomach virus, the grass is his way of clearing the pain, like we use tums, until you can have him looked at by a vet, feed him nothing but water, and maybe a little rice, I know it sounds weird, but my mother swears by it. It should soothe his stomach and ease his pain. He will get hungry though, but that's a good sign.

My dog was doing the same when he had parvo,take him to vet

His stomach is obviously messed up. Dogs eat grass to make there self puke when there stomachs are messed up. If it doesn't fix itself in a couple of days I would take him to the vet to make sure it is nothing serious.

Dogs(and cats) eat grass when they have a upset stomach
you probably want to take them to the vet!
