Question:
Some weeks ago, your column mentioned that resveratrol has been shown to help with digestive problems in dogs. When I mentioned this to my vet, I always thought that grapes are poisonous to dogs. Can you point me to the study that shows that resveratrol helps? We all need to understand more.
I am particularly interested in this substance for my dog because during a recent period of time when I had a rather abusive job situation, I got a great deal of relief from resveratrol for gastrointestinal symptoms. I believe it helped me take less of a very strong, and I believe, damaging medication. I am so much hoping it will do the same for my dog.

Answer:
Your veterinarian is right to question the use of resveratrol, which is derived from grapes (but also present in other fruits such as blueberries and cranberries) because grapes and raisins are toxic to dogs.
The National Canine Cancer Foundation endorses giving resveratrol to dogs because of its anti-cancer/anti-inflammatory and chemoprotective properties. It also protects the heart and is a potent antioxidant and free radical scavenger.
Other botanical products with similar properties and that can help various body parts such as the joints and digestive system include turmeric and ginger. Peppermint is excellent for irritable-bowel conditions.
At least one company is marketing resveratrol for dogs and cats, but more clinical studies are needed to evaluate the effectiveness of this product in treating various health problems in our animal companions.
