At first I was thinking pork chop bone, but then when I took a better look, it looks like some kind of animal. Unless, as the others have said that you have been in some kind of altercation or have upset the neighbors with the dogs barking, I would think that an animal brought the bones and obs into your yard. Sadly, I didn't know that corn cobs are bad for small animals either, though I would never feed one to my dogs (though Jack does like his corn). Hoping it is just an animal that brought those items into your yard and not anything more sinister.
