My dog ate an oatmeal raisin cookie. Are raisins toxic? Vet needed?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Small (up to 22lb) | Male | neutered | 2 years and 11 months old | 23.6 lbs

My dog ate a small piece of oatmeal raisin cookie I dropped before I could stop him. I'm not sure if there was a raisin in it or not, but I know raisins are toxic to dogs. Do I need to take him to the vet? He weighs 23 or 24 lbs.

Raisin toxicity is very poorly understood but most cases of ingestion do not cause any complications at all. There are very rare cases of kidney injury from grapes and raisins so precautionary intravenous fluids and repeated blood tests to monitor kidney injury are used occasionally but the benefit is not clear in such cases.

    Unfortunately the toxic dose of Arianism is not understood fully in dogs. Dogs have eaten cups for raisins or one raisin and ended -up with kidney failure. For this reason I advise you take Coco straight to a veterinarian. The vet will induce vomiting. To try and rid her body of the raisins she ingested. The vet will then start supportive treatments to help prevent kidney failure, such as intravenous fluid therapy. Time is critical with raisin ingestion, so the sooner you can take Coco to the Vet the better. Here is a source to provide further information and feel free to ask any further questions you may have; https://www.petcoach.co/article/10-common-foods-that-are-toxic-to-dogs-and-cats/
