Great product
I bought this for my senior dog who had sudden weight loss. We could not figure out what had drastically changed. After reading some reviews I decided she is well worth the expense. I started her on this product mixed in with homemade chicken and brown rice. She loves the stuff. It took a little time for her to bounce back and had us worried but, after about 2 months we saw a difference. We weighed her every month at the vet and she slowly got back to a healthy weight. She has been on myos for about 5-6 months now and she looks great. She loves the taste and almost demands the stuff. With a combination of this product and some others I found here on Amazon ( camallena oil) I really love how much healthier she looks and feels. She gets around better than before and is just overall much happier. I really think the kibble we were giving her had an ingredient change and it really made her sick. You really have to be observant of what these dog food companies do. Such a shame that better care is not demanded in quality control. At any rate if your pup needs to put some weight back on, give this stuff a try. It worked for me but, you need to be patient and give it time to work. I keep mine in the fridge and it stays fresh for the whole month. This is a win/win for our girl.

Amazing product!
This product is amazing. My dog has Cushings and she could bearly walk before giving her this product. Within a couple weeks I noticed a difference. Now about a month and a half she has shown huge improvement!

Works well
Highly recommend this. Gave my dog muscle and strength in her later years and she looked and acted way younger than her years. She was able to jump on couch and kept her agility.

Good product
After my 11 yr old pug slipped a disc and could barely use her back legs, she was put on kennel rest with no steps or jumping. Only going outside on a leash to do her business. Out of fear of her muscles atrophying, my vet recommended Myos. She’s been on it for over two months now and her strength and mobility have improved. She also takes muscles relaxers. I think the combination of rest, meds and Myos have helped and she has had no adverse reactions to it. It is expensive, but my girl is worth every penny. I do recommend trying it.

Definately works to regain muscle loss due to age/injuries. Noticed difference at 2 months.
I honestly didn't think this product would work and wondered how could fertilized age make a difference. The first month I saw little change but decided to give it another month before making a determination of the efficacy. At 1.75 months I thought I noticed a change in my dog's (Diesel) muscles. She has gotten bony in the hind end and along her lower spine. She has been having shakes or tremors in the back legs which had slowly gotten worse over several years. It effected how she ran, stood, etc. People always thought the shakes were from fear which was not the case. I thought she might have some spinal issue so took her to a Chiropractor that works on dogs. The Dr. adjusted her in a number of places along the spine and her tremors lessened a little. I started the supplement right after Diesel's first visit to the Chiropractor. At her second month visit the Dr noticed, as I had, that she appeared to have regained muscle in her back legs and along her spine. I told the Dr that I too thought I had noticed a change and she was regaining her strong, "beast-like" former strength but was afraid of just being hopeful. The Dr said that I was not imagining a change and that she too noticed a difference in Diesel's back leg muscle and muscles along the spine. Diesel just was not as bony as before. I gave the supplement at about 75% of what was recommended (3 scoops v. 4 scoops) due to it's expense. Even at this slightly lower dosage Diesel still gained enough muscle for both me and the Dr to notice a substantial difference. Now at three months of use Diesel has gained several pounds, the majority of which is muscle and not fat. Some other supplements have so much fat in them that the dogs will gain fat v. muscle. That is not the case with this supplement. Diesel lumbers when running when she gains a few pounds of fat so I know muscle was added as her performance has improved even thought the scale shows a 3 lb gain. I attempt to kept her weight at 62 or 63 lbs. Lean dogs live longer and healthier lives. One does need to adjust the food proportions the account for the added calories of the supplement so as to assure any weight gain is muscle and not added fat. But I am so please with the muscle gain in my nearly 10 yo dog that I am starting my 8 year old on it too. The younger dog, Quinn, doesn't yet show any muscle loss but I decided to start her on this supplement as a preventative (at a lower dosage) since nearly all older dogs loose muscle mass especially in the hind end . This causes difficulties in walking, running and rising up off the ground. Then they become weaker and weaker. Yes, it is damn expensive stuff but it is the ONLY supplement I have tried, and I have tried a number of the common brand, that has actually done what it says it will do. I have not studied or asked the company if this is a life-time supplement or not. Afraid if I stop now that Diesel has regained muscle mass she previously lost that were I to stop she might loose it again. I would highly recommend this supplement and just ordered my 4th month container. Be patient and give it at least two months before deciding whether it is worth it or not to continue. IMO it works. I wish I had taken some comparative photos. The attached photo is at the start of supplementation. If one looks closely one can see her leg muscles are not a pronounced as they should be. However, the best way to tell is to just feel the muscles when you start and at the end of each month of supplementation.

GAME CHANGER!!! REALLY WORKS
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.

Review of MYOS Canine Muscle Formula
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.

Do not recommend for anxious dogs.
I was so excited to try this since a lot of my favorite dog content creators speak highly about it. For context, my dog is anxious but she’s crate trained and loves to be in her crate. She is crated when she is home alone. When I started adding this to her food, she became more anxious while being in the crate for seemingly no reason when she usually sleeps in the crate. It got so bad that she cut her muzzle on the crate that has now scarred. When I removed this stuff from her meals, the crate anxiety went away and she would sleep instead of trying to escape. I’m disappointed at myself for causing this distress to her and she has a scar on her muzzle now that won’t grow fur back. I’m not sure if this product was the ultimate cause but I will not be risking it any longer. Would not recommend if you have an anxious dog. Disappointed that I had to throw away such an expensive product.

It's helping my elderly dog - excellent supplement.
My 14.5y.o has osteoarthrosis and whilst he takes a range of joint care supplements, because his exercise is now not as extensive as it once was - his leg muscles aren't as strong these days. A month of being given two scoops of Myos daily, easily mixed in with his food, I can certainly see the benefit and will continue to administer it. It is a little costly due to being imported to the UK, but for us worth it.

Miracle supplement
Our dog has muscle wasting due to steroids for an autoimmune disease, she couldn’t handle stairs, jump into the car, get on the bed and she was looking scrawny in her back end. This was recommended by our vet and what an amazing turn around! Our beautiful old girl now has a little meat on her bones, strength is much better and poops are the best they’ve been her whole life! This is a miracle supplement. Thank you so much for giving my dog a few years of quality life.

Excellent Product. Buying Again Definitely
We used MYOS muscle supplement for our dog after a recent injury when he was having difficulty walking, getting up on his own and climbing stairs because of weak muscles. After using it regularly, we noticed a very good improvement in his strength and mobility. He is now able to get up more comfortably and move around much better. The product quality is excellent and our dog had no side effects at all. Very happy with the results and would definitely recommend it. We will be buying the bigger pack next.

It Works for my woof!
Do not usually rate supplements but I’ve got to admit my 14 year old springador has certainly perked up on his woofie walks and the doggy physio has noticed improved muscle around his legs.
