My 13yr old lab had a bunny poop feast last week and it definitely did not agree with him. He went out in the back after breakfast and stayed out much longer than usual. I didn't think anything of it. When he finally came back inside he did not feel well at all. He walked around panting and finally threw up ( on the rug of course) these little brown balls. It took me a few minutes to figure out what it was- totally grossed out!
I was grossed out, but at the same time surprised about how sick it made him. I figured it affected him that way because of his age........Now knowing about your dog, maybe bunny poop just doesn't agree with dogs.
Hope both our dogs learn to stay away from it!

All of my dogs, (2 departed, 2 current), have gone mad for bunny poop, and it never bothered them one bit. I call it their Yappy Hour Hors d' Oeurves :) Heck, they lick their butts..how bad could a li'l bunny poop be? ;)

(Not to gross you out, but the two departed also ate live baby bunnies if they found a nest, also with no ill effects. I did feel awful for the poor bunnies.)

Your dog is just adding fiber to its diet. Since there is not much else in a rabbit pellet. If you truly want to stop her from doing this, then train her to leave it....

Rabbits do carry several parasites including coccidia and giardia, but I don't know how in the world you'll stop her from doing it. They all seem to love to eat it. Just make your vet aware of it if she becomes sick so he can take it into consideration.

I once had a dog who loved goose poop and had no problems finding it on almost every walk. I started using a penny can and it stopped her immediately.

Another idea that absolutely works is to go outdoors ahead of time and sprinkle the poo with cayenne pepper. It will keep the dog away from it (and the rabbits out of the yard!) It won't take long for the dog to associate the smell of rabbit poo with the pepper and you won't need to sprinkle it any more.

Good idea with cayenne pepper. Wouldn't mind the bunnies staying away too ... they keep eating my garden! :(

Thanks everyone! Good to know it's not just my crazy girl.

Rabbit droppings also can have tape worm ?
