Hello
So I took him to the vet and they think he stole someones chicken (packaged chicken) and ate it, which isn't unlikely because my dog is known for stealing things around the neighbourhood. He hasn't been sick in two weeks and doesn't seem to have any trouble going.
Thanks guys for helping I was freaking out.
Speaking of dogs stealing things, I once had a dog bring home a full set of stainless steel mixing bowls, one bowl at a time. I was never able to find out where he got them. I think someone fed their dog or put out scraps in the stainless bowl, and when that one disappeared, they put out another. My dog found them and brought them home, probably food and all, but by the time I found them the food was long gone. They were nice bowls though.
Hahaha I wish my dog stole useful things as well, he prefers to steal bags of groceries even if he doesn't like whats inside them. He once brought home six loaves of bread.
