My house dogs have always been fruitholics , in particular oranges , apples and pears. Della [Sh Ch.So Sad Cinderella] has a piece of each every day, it is impossible to eat fruit without sharing with her, I have even found stalks , where she has helped herself , probably fed up of waiting, must say it is the first time I have heard about grapes being bad for them, we always share a bunch of grapes!!
