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.

More Than Two Decades of Clinical Experience with DogtorRx

Dr. Buchoff’s relationship with DogtorRx Longevity 4 Pets began in 2006, when he became involved in evaluating the standardized oligopeptide formula in his veterinary practice at Holistic Pet Care in New Jersey.

During Dr. Buchoff’s clinical evaluation, more than 65 canine and feline patients received the standardized oligopeptide formula. Reflecting on his clinical observations, Dr. Buchoff reported:

“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.”

Dr. Buchoff also reported benefits involving strength, energy, stamina, alertness, disposition and agility, as well as improved appetite and healthy weight gain in some animals. He recommended the formula for maintaining and enhancing quality of life in healthy dogs as well.

Continuing the Research — 2006 to 2026

Twenty years after Dr. Buchoff first became involved with DogtorRx Longevity 4 Pets in 2006, the collaboration is entering a new phase of veterinary research.

Dr. Buchoff and DogtorRx are now undertaking a pilot study evaluating a novel nutritional approach to regulating elevated luteinizing hormone (LH) in dogs following gonadectomy.

The new investigation is particularly relevant in light of Dr. Buchoff’s original 2006 clinical observations regarding standardized oligopeptides and hormonal imbalance. The pilot study will investigate whether administration of DogtorRx Age Defense Extra Strength, containing the standardized oligopeptide complex, may help regulate LH levels in gonadectomized dogs.

The study represents an exploratory investigation intended to generate preliminary clinical data and determine whether the observed response warrants a larger, controlled veterinary study. No conclusions regarding efficacy will be drawn until the pilot study has been completed and the resulting data evaluated.

For DogtorRx, the project marks an important milestone: 20 years of collaboration with Dr. Gerald Buchoff, from his initial clinical evaluation of standardized oligopeptides in 2006 to the investigation of their potential role in canine endocrine health in 2026.

Today, Dr. Gerald Buchoff is the Director and owner of Longevity Veterinary Center and Holistic Pet Care in Whippany, New Jersey, a state-of-the-art integrative veterinary center dedicated to helping pets live longer, healthier lives. The Center combines conventional veterinary medicine with a comprehensive range of holistic and integrative therapies, reflecting Dr. Buchoff’s longstanding commitment to advancing veterinary medicine through an integrative approach to health, wellness and longevity.

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.”

“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.”
