apes – To feed, or not to feed? For a long time, there’s been an ongoing debate about whether or not grapes (and raisins) are toxic to dogs. I’ve discussed the question of grape toxicity in dogs some time ago on one of my past radio shows, and I admit that I have always been skeptical of this because many of my clients have fed grapes and raisins in small amounts and never had any problems.
But several veterinarians have provided some recent evidence and personal experiences that convinced me that there is some validity to the issue. My own suspicion has always been that the root cause is a fungal toxin that causes some dogs to get sick (through renal failure), and this theory is supported by the fact that this toxicity occurs even among dogs that consume organic grapes (organic produce should, in theory, rule out pesticides or chemical toxins as a culprit). But the latest news appears to indicate that copper compounds may be the underlying factor for the potential toxicity of grapes and raisins. Why?
Copper compounds are often used in organic farming as an fungicide (fungus is one of the most common problems in commercial grape operations). Some breeds of dogs, especially the West Highland White Terrier, Bedlington Terrier, and Doberman Pinscher, tend to have a genetic predisposition and sensitivity to copper. So, copper compounds infused into grapes combined with breed-specific genetic sensitivities could explain why some dogs are affected while others aren’t.
The bottom line: There are many factors that determine whether dogs will be affected by grape (and raisin) toxicity. Unless you know the exact source of your grapes (and can confirm that copper compounds are not being used as a fungicide), it’s probably best to omit grapes from your dog’s diet. When in doubt, leave it out!
