Grape Toxicity in Dogs: What You Need to Know
Grapes and raisins are a common ingredient in many human foods, but did you know that they can be toxic to dogs? Grape toxicity in dogs has been a long-standing concern, and it's essential for dog owners to understand the risks and take necessary precautions.
Grape and raisin toxicosis occur when a dog ingests fruits from the Vitis genus, including grapes, raisins, Zante currants, or sultanas. These fruits can cause acute kidney injury (AKI) in dogs, and the exact amount of fruit required to cause toxicity is unknown.
Why are Grapes Toxic to Dogs?
The exact mechanism of grape toxicity in dogs is still unknown, but it's believed that some component in the fruit, such as tannins, flavonoids, and monosaccharides, can cause a dog's kidneys to fail.

What to Do If Your Dog Eats Grapes
