That reminds me of a funny thing. My father has pear trees that are very old (the house was built in 1878, but they aren't that old). The trees produce some decent pears, but my father doesn't do anything to or with them. His dog, however, loves pears and eats all that fall on the ground, which is alot this time of year. The dog also eats the tomatoes off the vine. I've never heard of a dog that does that.
