The danger: acute kidney failure; potentially fatal.
Reactions vary with the dog’s size and how much they ate, and there is no safe home remedy — treatment for grapes poisoning is a job for a veterinarian.

Call your veterinarian or ASPCA Animal Poison Control at (888) 426-4435 immediately. Do not try to make your dog vomit unless a professional tells you to. If you can, note how much they ate and when it happened — that helps the vet decide on treatment.
