What a grape, err I mean great, costume idea! It may not be a pet-safe snack , but it's a neat ensemble nonetheless.
Turn your own dog into Grapes on a Vine . . . on a dime! OK, more than $.10 but this costume can easily be had, especially if your pup already has a green coat or sweatshirt.
To create, simply blow up purple balloons (or choose red or green balloons for your favorite flavor ) and hot glue them to the coat. Add on some leaves cut from a garland and you've got a fine costume on your hands — just be sure to place the balloons where your pup can't accidentally pop them and put it out of reach when the photo opp's done.
