I was skeptical at first but liked the research that had been done on cancer in dogs. This is a concern of mine too. We already lost one Golden Retriever to cancer and have another Golden now. (Both therapy dogs.)
I tried one order and the additional bonus price order, each consisted of 3 bags.
It took approximately a week before we noticed a difference in Angel. She seems more playful and energetic. If my wife and I hadn't seen physical proof of her change in behavior we wouldn't be writing this review.
Therefore, I would definitely recommend Dr. Marty's to any dog owners who love their fur babies enough to help them fight against cancer and have a longer and healthier life.
Bottom Line: Yes, I would recommend this to a friend
