Customer Reviews
Seems to be a great product for our senior lab
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
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! 🐾💙
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
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.”

It’s amazing to see the difference! Harpers age was catching up with her, and she seemed to lose her zest for life. After starting DogtorRx, she’s back to her old playful self. Her mobility has improved, and her energy levels are much better.

My 15 years old Husky mix Blanca has been suffering from Cushing’s for years, she’s been on Vetoryl 10mg in the morning and 10mg at night. After two and a half on Vetoryl she has outlived most statistics. I feed her low fat hi protein formers chicken formula plus boil her chicken and prescription diet metabolic can food, which she alternates between, whichever she has appetite for. I read a blog post by a holistic veterinary care clinic in Oakland, CA that refers to a scientific article on DogAware.com where DogtorRx was mentioned as an alternative natural supplement to address Cushing’s. I immediately ordered 2 bottles for both my dogs. My Blanca would have died if it wasn’t for DogtorRx which saved her life. Both my dogs are on it and I documented Blanca’s recovery in a video journal that I sent to DogtorRx. I can’t say enough positive things about DogtorRx and highly recommend it for dogs suffering from Cushing’s.

My boy Sammy he is a 15 years old shepherd chow mix. He has been on the DogtorRx joint supplement for 3 months and look at him. Go baby, no stiffness and no arthritis. He is enjoying life. I recommend DogtorRx to any pet owner who wants to alleviate his pet’s stiffness and arthritis.
Joseph –
Amazing stuff, my dog is happier, has more energy and clearly more comfortable, really impressed and would definitely recommend DogtorRx for the older dog population.
Vicky –
My 11 year old beagle had TPLO surgery this year and I put him on DogtorRx right after the surgery. His recovery has been amazing and I’m sure the DogtorRx has helped him become more agile. I couldn’t recommend them enough for any dog with age related problems.
Clara –
We’ve started our 11 year old miniature schnauzer on the DogtorRx tablets and what a difference they’ve made! He is like a puppy again!! Jumping on the bed, back to climbing the stairs, and loves walks again. I’ve recommended them to my friends for their dogs, and I cannot recommend these enough wherever we’re with our baby boy.
Tanya –
A product that really works for my dog!
Rhonda –
If it wasn’t for DogtorRx my 14 years old Skippy wouldn’t be with us!
Michael –
I’ve been hesitating to give another joint supplement to my dog after having so many promised great results. But after landing on the DogtorRx Homepage and watching Ace’s incredible recovery from arthritis I couldn’t not give DogtorRx a chance. I can’t say enough how glad I’m for taking the chance and giving it to my 15 years old labrador retriever whose recovery from arthritis has been amazing. There is real science behind this product and nothing like it on the market. Anyone with arthritis don’t hesitate like I did! Order it and you’ll be as happy you did as I’m! And your dog will thank you for it and give you many more memorable years.

Cushing’s is a nightmare and we were contemplating putting our 14 years old beagle down. This product is not known, but thanks to relentless search we found it. I don’t wish on anyone the emotional rollercoaster we had to go through over the past year. Brie is well and happy, no more sleepless nights and rushing to the vet. Give DogtorRx a chance to get back the dog you once knew.
