Seems to work. All natural herbs.

My dog has a limp in his back leg. This product helps him limp much less, while helping him have more energy.

My dog is roughly 100lbs (50kg). He should have about 4ml twice daily. However, i gave my dog 5ml, 5 times a day for the first week, then dropped down to 3 times a day. Roughly about 2 bottles in the 1st week. And all off a sudden he was eating again. Chewing his bones again. Barking when the door knocked. Running up and down the garden. Playing with a football. I also give him extra doeses of hawthorn tinctures throughout the day(at least 5 times, even after the 1st week. Him having young at heart twice daily didn't do much, if anything. I would give him it twice a day as a preventative. Young at heart will not work properly if you give your dog medicine such as cardisure and fortekor. I chose to take him off his tablets as he was getting worse and worse. You need to give young at heart at least a week to start working and will not work the same day.

This product has given my dogs years more to live. He was given 6months to live, he has enlarged heart & grade 6 heart murmur. that was 3 years ago. He is doing great & my vet said he’s amazed at how well he is doing.The black ring on dropper is NOT mold. It is naturally occurring separation. I phoned the company to ask. My dog has gone through more than 20 bottles & each bottle has it.

Took my boy to see the vet fir his heart murmur and they said he has improved. I wad sceptical at first but it's been a game changer for me and my boy

My dog has been having these drops for many years and the vet says his heart is super healthy and he’s 11 now. It replaces the Taurine omitted from lots of dog food.

My male chihuahua was diagnosed with heart disease July 2016 [9 years old, grade III/VI, degenerative mitral valve disease], and at the time, his veterinary cardiologist did not recommend or suggest any supplements to support his heart. Because I was so relieved that he did not require any medications at the time, I was totally okay with just continuing to do what I was always doing. One year later, July 2017, we went back to the cardiologist for a check up - I got another great report stating that his heart disease has not progressed. Once again, I asked about anything I could give to support the heart, and he said that there isn't any research out there that suggests supplements in pets slow down the progression of the disease. At this point, I was not satisfied with that answer and went out to do some research on my own. That's when I read about Hawthorn in humans and how in people with valve issues, this tincture has really improved their cardiovascular health - so of course, I had to try it out - PLUS it's bacon flavor, a big hit with a sometimes picky chihuahua.Angus has been receiving this in his food twice daily, 5 drops each meal, since November of 2017. He does get an echocardiogram every 6 months, but the cardiologist visits are only once annually. July 2018, the cardiologist was genuinely surprised by Angus's progress, or lack there of in this case, and reported that Angus is "beating the odds" and that he has static heart changes from last year. What pet owner wouldn't want to hear that?? Angus has never refused his food because of the flavor, each bottle has arrived intact, quickly through Amazon, and the dropper is long enough to get every last drop out of the bottle!Angus turns 12 next month, and just had his 6 month echo performed with still the same numbers and report. I hope to update this in July to see what changes, hopefully none there will be. It could be that I am lucky, and this supplement doesn't help at all, but reading the human articles and studies, I believe that to be not quite the case. I know at some point Angus WILL need heart medications, but the idea behind this supplement is to push that off as far as possible. He also eats a raw diet, gets Ubiquinol, Antinol, and CBD oil - he also gets quite a few joint/dental supplements but those are not related to heart health (:If any of my dogs develop heart disease due to a valve issue in the future, I will always go to this supplement. And always let your veterinary team know ALL supplements you are giving your dog, especially something like this, because it could alter the way medications work for your pet.NOV 2019 UPDATE: So Angus had another echo last week, and at this time, there is a recommendation to start Vetmedin. He now has a 4/6 murmur but still in stage B2 (which he has been in since at LEAST last year). On a positive note, Angus has gone for 3.5 years without needing any medications and even now, he is doing EXCELLENT! I have not noticed any coughing, exercise intolerance, lack of appetite, nothing -So overall, I truly believe that this supplement has given Angus even more time with me, and starting Vetmedin now is still a proactive approach (based off of the EPIC trial study that was done). He is turning 13 in Feb, and I am very happy with how well he is doing overall.

This product does work for my 11 year old Yorkie, Louis, who was diagnosed with tracheal collapse, stage 2 congestive heart disease and flooded lungs.He was prescribed 2 diuretics and Vetmedin. This dog is like my child and his diagnosis, along with the way he started backing away from walks, scared me into researching nonstop for a month on diet and supplements and the effects of medications on senior dogs.Along with this product, the holistic vet recommended adding Ubiquinol (more readily available Co-enzyme Q10), calcium powder, Spark supplements and krill oil (this helps with heart, brain and bone health). The biggest change happened when we switched out his diet from kibble to Stella and Chewy's raw food. These supplements and diet changes created MIRACLES for my puppy! No more coughing and he moved so much better when he walks.We tapered off the medication by 10% every week so that his heart and lungs would not suddenly go without help from the Vetmedin and diuretics. The food took 2 months to fully transition from expensive "limited ingredient" kibble to Stella and Chewy's raw meat frozen patties. I did extensive reading before giving this product a try and found out that it is dangerous to suddenly stop giving him the Vetmedin. Building up the dose of Young At Heart For Dogs and tapering off the prescriptions safely and taking him to the vet every 2 weeks to monitor his liver and heart condition helped a lot. When I first took him to the vet for his condition, he could hardly walk around the building of my apartment. This was a dog that used to jog 2 miles with me up to age 11. :( We are 2 years after I noticedhis shortness of breath. At 13, his heartbeat is more normal and there is no coughing, thanks to this product. Through careful monitoring, I have him at only 20% of the Vetmedin that was prescribed and 25% of the diuretic medication. He also gets the Milk Thistle and the Kidney Health to protect his liver and kidneys from the Vetmedin.Bottom Line: Please do NOT just stop your dog's medications and replace it in one dose. It might work better to taper off the Vetmedin to give the supplements time to absorb into your dog's system. Read the effects of these medications AND what happens to dogs when you feed them kibble. I will never feed a dog kibble (ours was VERY expensive and "high end") again.
