DogtorRx

Veterinary Approved
Rejuvenation Supplements
DogtorRx has been clinically tested and approved by veterinarians across the USA. In 2005, Dr. Ava V. Ackerman, DVM, at Belmont Pet Hospital in Belmont, CA, conducted the first study evaluating the safety and effectiveness of our standardized oligopeptide formula.
The study focused on aging dogs with orthopedic issues and those with suspected or diagnosed Cushing’s Disease. The results were remarkable, showing significant improvements in dogs suffering from Cushing’s Disease, osteoarthritis, dysplasia, and inflammatory joint disease – with no adverse effects reported.
DogtorRx continues to provide trusted solutions for healthier, happier pets.

I conducted the first study to support the safety and efficacy of standardized oligopeptide formula. The study focused on aging dogs with orthopedic challenges and dogs with suspected or diagnosed Cushing’s disease. Laboratory work, including chemistries, CBC’s, thyroid and cortisol levels, was performed both before and after the administration of standardized oligopeptides. No adverse effects were noted. One participant, an aging Labrador Retriever with significant mobility problems, was taking Rimadyl and Glucosomine prior to the study with little or no results. The owner was considering euthanasia. Within a very short time after adding the formula to his diet, the dog became as mobile as a puppy. Nothing else as added or changed in his treatment. Now, two years later, this same dog is taking only the standardized oligopeptide formula and no more drugs. Remarkable results were also shown on dogs with Cushing’s disease who became active and playful again once put on this regime. Presently, I have about 25 patients taking this formula and the responses are overwhelmingly positive.”

“The standardized oligopeptide formula is having profound effects on over 66% of the 65+ canine and feline participants in an ongoing clinical study at the Holistic Pet Care clinic, New Jersey. It is especially beneficial in cases of hormone imbalance and neuromuscular deficiency in older dogs. Benefits are also reported in areas of strength, energy, stamina, alertness, disposition and agility. Many with poor appetites are once again enjoying food and gaining healthy weight. I also highly recommend this formula for maintaining and enhancing the quality of life for healthy dogs, as well. It varies, but I have about 45 patients on this formula.”

“In my veterinarian practice, I routinely treat dogs suffering from Cushing’s disease, joint-related issues, and from geriatric conditions. I have always been an advocate of preventative health care and the necessity of high-quality nutrition in the daily diet to promote good health and maintain a healthy life. This past year I was introduced to a new dietary supplement for dogs and cats containing standardized oligopeptides, and I now recommend them to all of my canine and feline patients to be incorporated with existing prescribed treatments. I have personally witnessed extremely impressive results within a relatively short period of time on dogs diagnosed with Cushing’s disease, and I have seen favorable results when treating dogs and cats suffering from arthritis, diabetes, hot spots, anxiety issues, hip dysplasia, and liver toxicity. Also, many geriatric dogs have now shown increased energy and mobility and a demonstrable appearance of overall well-being. Recovery time for dogs recuperating from surgeries has also been reduced. I recommend this proprietary formula for dogs and cats of all ages, to be used as a daily tool for
good health maintenance and as supplement to be used along with their existing treatment program.”

Growth Factor
Rejuvenation
Since the launch of our first standardized oligopeptide pet supplement, tens of thousands of dogs and cats have experienced the natural benefits of growth factor therapy.
As dogs age, their joints ache, muscles weaken, and mobility declines, making it harder for them to enjoy life as they once did. With our rejuvenation growth factor therapy, we naturally repair joints, ligaments, and tendons – relieving pain and restoring mobility so your dog can stay active and happy.
