I am asking this question because a month or so ago I left a bunch of bananas on the back step of the house. In the morning they were gone. I wouldn't think too much of it except that a few days later a plastic bag of eggs appeared - I ate the eggs, they were fine.
I forgot about this till yesterday. At the weekend I decided to make myself a compost bin out of a plastic dustbin turned upside down and the bottom cut out of it. I filled it with bits of banana trunk and some chopped up flower stalks and then added all the left overs from the days food preparation, including some limes that had gone soft. In the morning all the left over food had gone.
Now I can believe that some hungry dog might just take the bananas and possibly bring me a bag of eggs in exchange but I don't think that a dog will take the lid off the compost maker, eat rotten limes and then put the lid back on.
