This morning I got up to find that the chipmunk has discovered my back deck and the mother load of grapes. He was checking out my potted tomatoes when I first saw him. Then he went on to enjoy the grapes. After battling him last year to prevent his burrowing under my front stoop, I don't know what to do about this new turn of events. I can't put down the "stay away" crystals on the deck because little dog uses it. She likes to smell the chipmunk but doesn't keep it away. It's times like this that I miss big dog. He would have a blast guarding the grapes. He was a good hunter and always made sure there were no rodents in my yard.Any suggestions on how to save the grapes without harming the dog? I'm putting on my camo face. It's war chipmunk!
