Why grapes are dangerous
Grapes and raisins can trigger acute kidney failure in dogs, and the toxic dose varies so wildly that no one can say how many is safe. Some dogs are fine after a few; others collapse after one. Because you cannot predict which dog will react, every exposure is treated as potentially serious.
What to do if your dog ate grapes
Call your veterinarian or an animal poison control line immediately. Do not wait for symptoms. Faster treatment — inducing vomiting and IV fluids — greatly improves the outcome.
- Note how many and roughly when they were eaten.
- Keep grapes, raisins, and foods made with them (bakery items, trail mix) out of reach.
- Watch for vomiting, lethargy, reduced appetite, and reduced urination in the following days.
Watch for these signs
Early signs are vomiting and lethargy; later signs of kidney failure include reduced or no urination and weakness. By then the damage is advanced, so act early.
