What is the oddest thing your dog has ever eaten?

my dogs like to eat rabbit shit.

 

Dog ate part of her neighbors dog collar. Or rather had part of it in her mouth when she came over to me, and I thought, 'oh my god she's a cannibal.'

For some reason that seemed more likely then the collar falling off and the dog chewing on it.

 

I want a dog. There's plenty of stuff in my place he could eat.
