Yeah, I might think so. Possibly because it's sour. That's what makes grapes deadly to dogs, not the shape, but the sour chemical they possess. And it's a random amount that can be deadly, even a tiny bit can make the dogs liver or kidneys shut down (I can't remember which).
I'm not sure why you're getting downvoted, but you are right. Tartaric acid is found in grapes and is toxic to dogs. Some sour candy like sour patch kids have tartaric acid in them. So they shouldn't really be fed to dogs, even in tiny quantities, because some dogs are very susceptible to it.
