Great supplement to help with age related muscle weakness

David M.January 4, 2026

Myos has made a huge difference in my senior dog's life. My almost 16 year old dog was starting to have weaker legs and in general a weaker backend. After reading about this product on a message board I asked my vet about it. She wholeheartedly agreed that this would be a good supplement to give my dog. Since giving it to him he appears to have stronger legs and less stiffness allowing him to continue with his daily walks. He has a sensitive stomach and this has not caused any GI issues. It's been a great supplement for my senior dog. Read more

GAME CHANGER!!! REALLY WORKS

Mary AshmanDecember 8, 2025

My vet recommended this as my 11.5 year old doodle was getting weaker in the back legs and the one leg would shake at times. I tried this and boy after about 2 months there is a huge difference. I am also giving it to my other 11 year old girl. Her back leg no longer shakes. There is a noticeable difference in her walks and play time. Both girls want to run and play in the morning before eating breakfast. They tear around the back yard chasing each other. I highly recommend this to anyone with an aging dog as it does build muscle. Give it about 2 months to see a difference, and give it daily as directed. I heat up broth and stir it in with their probiotics and this supplement and pour over their food. It must taste good as they eat it with no problem. Read more

Review of MYOS Canine Muscle Formula

Christian J CaliAugust 6, 2025

MYOS Canine Muscle Formula: As a pet owner who prioritizes my dog’s health and longevity, I am thoroughly impressed with MYOS Canine Muscle Formula. This supplement is formulated using Fortetropin®, a clinically studied ingredient derived from fertilized egg yolk powder, which has been shown to support muscle growth and reduce muscle loss in canines. In my personal experience, this product has been exceptional. After incorporating MYOS into my eleven year old dog Bolt’s daily regimen, I noticed a clear improvement in muscle tone and strength over the course of several weeks. My dog, who had previously struggled to maintain muscle mass due to age-related loss, has gained visible muscle weight and now has improved stamina and energy during play and walks. What I appreciate most is that this product is easy to incorporate into meals and is well-tolerated by my dog. It has exceeded my expectations in supporting muscle health, and I am very happy with the results. Conclusion: MYOS Canine Muscle Formula is an outstanding supplement for dogs in need of muscle support—whether due to aging, recovery from injury, or maintaining overall fitness. Based on my experience, I highly recommend it to other pet owners looking for a safe, effective way to enhance their dog’s muscle health. Read more

Jury's still out on this product... 3.5-4 Stars at this point...

coffee&booksNovember 15, 2019

** Jan. Update Cont. ** Raised to 4 stars for the incredible customer service we've received from MYOS. With their support, we are continuing the Fortetropin & hoping for quality of life improvement. We are not in the market for creating an immortal dog. Unfortunately, they just do not stay with us long enough. Our primary goal is comfort through the aging process, and mobility. We do not have a definitive diagnosis on what's causing the muscle loss in his legs (primarily back legs, and front legs but to a lesser degree). My gut tells me that this product provides significant support to dogs convalescing from surgery or illness - and I would encourage you to give this product a try! For chronic illness/disease - I think the most rational goal to aim for is comfort and slowing down decline. This is what we're hoping for, and I'll continue to update. Our thanks to MYOS for helping us continue w/this product & their great customer service. Tip: I've found it mixes best with canned food that has NO gravy or liquid. It has a course parmesan-cheese consistancy/texture, and mixes better with a "pate" style dog food. It has no flavor or aroma - and our dog has no sense that it's in his food (or else he'd turn his nose up at it). If your dog is on kibble - add warm water to the food to soften (plus dogs just like it, and hydration is so important) - then sprinkle on top. I've also taken a high flavor canned food (for fun, not part of his regular diet), combined a spoonful with the fortetropin, and created meatballs (when he was on a prescription food that was somewhat soupy). *January Update* - we were unsure of whether or not to keep going, but will continue with Fortetropin - and stay hopeful that we can see more significant improvement. I want to report that one important thing to note is that our dog has not declined since being on this product. Improvement, so far, as been slight. As we continue with Fortetropin, I plan to get our veterinarian involved to help document any changes at this point, and will share the results here. I see so many people reviewing this product with the same hope that we have - and I think sharing our results is so important. I continue to recommend that people at least try this product - as it could just be that certain conditions will respond better than others. Stay hopeful! :) Just completed our first container of this product. My 12 yr old collie has had declining muscle control in his back legs for the past few years that has come to a point where support (nutritional, medication, supplement, etc) is required. He has not been diagnosed with Degenerative Myelopathy at this point, and we suspect it has more to do with a spinal condition. That said, the atrophy is significant, especially surprising in his front legs (given they're providing much of the support for his body at this time). Pros: It didn't cause stomach upset, it was easy to administer/mix into food, and there could be a slight amount of increase in muscle mass, but it is VERY slight. Cons: Extremely expensive. I don't think it was a waste of time or money to try this - and I would encourage people to give it a go (it can't hurt). In our case, however, the improvement was not so notable that I am clamoring to buy the 2nd container. Still contemplating it at this stage. I will continue to update. I would rate it 3 1/2 stars at this point, but will change this rating if we see more noticeable improvement. Read more
