Yes, I was cutting a watermelon for myself and a piece dropped on the floor. As luck would have it, there was a dog nearby to scarf it up. In fact, it was Misty. Soon the others came into the kitchen to see what the foster girl was doing. It seems that dogs have a keen awareness when others around them are eating, whether that be other dogs or humans!!
I couldn't resist and gave them each a bite of the luscious fruit. Sure enough, all of my hounds liked it too and they wanted more!! It's always fun to watch them try new fruit (of course no grapes as they are toxic).
By the way, the watermelon was seedless so no seeds in their tummies to grow watermelon vines!! :)
