Seems to be a great product for our senior lab

04/17/2026

We have been using this brand for a month now. I bought this brand to replace our usual brand because this one is much cheaper and I wanted to see if we could save money. Our “senior” lab is having an expensive golden year period! To be transparent we have been giving him a similar product but different brand daily for a year. We also give him CBD for dogs daily. He has hip pain and often limps with flare ups. Prior to the change he had been doing well so this was merely a transition to see if he would respond well to an equal product but possible cheaper product. So far so good! We have seen no set backs in his mobility or pain response. He is moving around as normal since the change. He has tolerated it well and we saved a bit of $$ by trying this brand. I feel like the quality is equal to the higher end we were using and the cost is better. He doesn’t act like he has noticed a change when he takes it as we put it in his food and he hasn’t seemed to notice. I am pleased so far with this product and will continue using it moving forward.

DogtorRx Age Defense Joint and Mobility Support supplement for dogs

04/15/2026

This supplement arrived extremely quickly, well packaged and in perfect condition. It arrived on 10 Apr 2026 with a Best By date of Oct 2026 listed on the bottle, so I consider it sufficiently fresh. Our dog is 2 years old and weighs 50 pounds and is in good health. I wanted this supplement to help maintain her general health. The recommended dosage for her is 1 tablet twice a day, per package directions. Product images are a bit confusing since one of them says 2 x day for her size and “Give the recommended amount morning and evening” so judging by directions on the packaging that means split the dosage up into 2 feedings. Since this is for maintenance, we have been giving her 1 tablet each day since it arrived. She has had no negative side effects. Product images and info suggest you can give it as a treat and she did indeed wolf it down when we gave it to her straight by itself, but she is really super about taking pills so I can’t call that a guarantee of palatability. Given the ingredients included in this supplement and the info provided, I have confidence that this is a safe supplement that contains essential nutrients for the health of our dog, and particularly beneficial to the health of aging dogs.

Nice small pills that the pups take without issue! Just started using so hopefully it helps support their joints as they age.

Perfect for senior dogs—happy 12th, Milo! 🐾💙

04/13/2026

My boy just turned 12 today, and this has been a great addition to support him as he gets older. Mobility support I’ve noticed it helps with his movement and overall comfort, especially as he’s starting to slow down a bit. Well-rounded formula I like that it supports more than just joints—there’s added support for immune health, skin, and overall vitality. Easy to give The tablets are easy to give, either on their own or mixed into food. Quality Made in the USA with solid ingredients, which is always important to me. Bottom line A great supplement for helping senior dogs stay active, comfortable, and thriving as they age. 🐶✨

Very excited to see how well these work over time

04/12/2026

Even though my boys are not old, I love to be thorough. This age defense combines so many supplements together into one pill. They have a slight enticing scent for dogs in them. My only problem is the fact that it is a pill, sometimes it is hard to get your dog to let you give it to them. Maybe mixing it into the kibble, or putting it into a pill pocket would be more efficient. Overall excited to see if this will improve, or prevent anything.

“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.”

“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 Glucosamine 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 was 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.”
