This is the first in a series of posts in which we will be discussing different canine cancer supplements, what they are used for, and how they may fit into your dog’s cancer treatment program. While some supplements are only available through veterinarians, many can be purchased over-the-counter. PLEASE NOTE: Always consult your veterinarian (and oncologist) before making any changes to your dog’s diet or supplement plan to ensure that you are not inadvertently counteracting any conventional medical treatments or potentially creating any additional health issues.
With the wealth of information available now in books and on the internet about canine cancer, the average pet owner will find dozens of recommendations regarding supplements to use to help fight cancer. It can be overwhelming — especially if you are not one of the fortunate few to be able to work with a holistic, or holistically-minded, veterinarian. In these cases, pet owners often take it upon themselves to design their own supplement program for their dog, which usually includes several different products. It’s not uncommon for dogs with cancer to begin taking 5-10 different products to help with everything from digestive upset to immune system support. That’s a LOT of supplements to keep track of!
ONCO Support by Rx Vitamins for Pets is a cancer support supplement that aims to eliminate the need for so many different products with its proprietary blend of cancer fighting nutraceuticals and botanicals. Developed by Robert J. Silver, D.V.M., M.S., C.V.A., this formula can help “increase patient vitality as well as improved immune system resistance.”
If you’re familiar with the basics of canine cancer supplement recommendations, you’ll recognize many of the individual ingredients: L-Glutamine, L-Arginine, Medicinal Mushrooms, Green Tea Extract, Vitamins A & D, Selenium, and the list goes on. All conveniently balanced to help you keep your dog as strong and healthy as possible throughout their battle with cancer.
ONCO Support is only available through veterinarians and is already being used by many of the major animal cancer centers across the country. It is also recommended by many holistic veterinarians including Dr. Shawn Messonnier, author of “The Natural Vet’s Guide to Preventing & Treating Cancer in Dogs” and “Unexpected Miracles.” If you are interested in finding out if ONCO Support may help your dog, talk to your vet and find out if they are familiar with the Rx Vitamins for Pets line of products. They can then contact the company to receive extensive information on the science behind ONCO Support and how to successfully integrate it into your dog’s care.
If you would like to receive an electronic copy of the ONCO Support brochure to share with your vet, please email us at georgiaslegacy@fightcaninecancer.com so we can send you the file. Your vet may thank you for it!



Rx Vitamins is a great company with terrific line of products, I will check out this new product. Because your list shows L-Glutamine as the first ingredient of this new supplement Onco Support, I believe that a high dose of L-Glutamine must be included – the main ingredient. PLEASE include with your info that any dog who has ever had a seizure, or who is taking anit-seizure meds (for chronic pain for example) should not take L-Glutamine at all.
Thanks for posting this Laurie — will add to Facebook too. Just another reminder of why it’s so important to discuss any supplements with your vet before administering them to your dog.
Onco Support says one scoop per 50lb…soo HOW MUCH is a SCOOP?
I have seen everything from 1-2 tablespoons
According to Rx Vitamins, one scoop is equivalent to 1 Tablespoon. It’s possible that some vets may recommend a higher dosage than the standard amount due to specific circumstances, but the recommended dosage is 1TBS per 50lbs.
The “SCOOP” is included in the container. So, it’s 1 of those.
My little Maltese is 8 lb. and is recovering from Fibrosarcoma surgery. How much should he have? I already started giving him K9 Immunity Plus, Is Onco a better product for him now?
