Bet you've got a cat whose being let outside nights or a couple of strays have found their way into your yard nights after raiding the garbage. If you watch cats, they make several trips to the source of their scavenged food, usually someone's garbage, and jump or climb the fence into the yard to hide their food. Birds and squirrels come along and find their food and eat part or all of it and leave it lying about or your own dog can find it. Other cats do to and sometimes if scared by someone coming by, they will run, leaving their half-eaten food revealed in the yard for your dog to find. Large birds also bring things into my yard.
