While my dogs are on this supplement there is no way to know if it is working. They’ll continue to have regular checkups with their vets and con monitor them with bloodwork.

My Maltese has an enlarged heart. He gets Cardiac support, Enalapril, Lasix and 93% Turkey meat mixed with Dr. Marty’s Nature Blend. It has been over a year with his diagnosis and he’s doing fine.

Although this review seems to be placed under the reviews for calming support, I am not sure which product is making the difference in my dogs. I have them on 4 Fera Pets products. Cardiac support, calming, probiotics and post biotics. My male dog is 11 and he has mitral valve disease. His heart has enlarged due to his cardiac disease. We saw a change for the worse and started him on Cardiac support just after we began a second heart medication. I am not sure if it is the combination of both, or one over the other, but there is a positive change in him so I will continue with both therapies. My female who is 8 has been experiencing stomach upset for a very long time. We have tried everything ! She would wake at 5 am or earlier many mornings. I would wake earlier because her belly would gurgle so loudly. As soon as I heard it, I knew she would be waking me to go outside to eat grass and would not eat her breakfast. I have her on calming support plus the pro and post biotics. She is like a new dog and she isn't even consuming the recommended daily allowance yet. It is quite evident that she is feeling better, she is not waking early, not looking to go outside to search for grass and is excited to eat her daily meals. She is playing more and it warms my heart to see her feeling so well. I will forever supplement my dogs with your products. Thank you!

We are very happy with this product and continue to use it daily and our dog food. We have two Cavalier King Charles Spaniels and they prone to later cardiac issues! We feel like using this product will help them in their later life also! It taste fine my dogs don’t mind it. I open up the capsule and put it in their food! We are very happy with this product!

Our Tucker was diagnosed with a mild heart murmur by 2 different vets ( in the same office). I decided to try the cardiac support since he was only 6 years old. Within about a year or less our primary vet said the murmur was completely gone. Is there a connection? I don’t know, I can only share our experience.

Very happy to have found this product. Vet gave it the thumbs up too! I like knowing that I am doing a bit more to help my dog with his heart murmur as well as the prescription medication. My dog is tolerating it well….i sprinkle 1 capsule on his lunch every day.

Our dog has a heart murmur, high blood pressure, and a mass on his heart. This has kept him healthy and in good spirits. We're grateful for this supplement and will continue using it!

I just got this last week and started my little 5 pound Chihuahua heart dog on it. The capsules were too big and she wouldn’t eat her food with it on it, so I devised a plan of getting empty tiny pill capsules online and filled the capsules with the contents of the Cardiac support. I give her the capsules throughout the day in a little cream cheese and we are getting the cardiac support in her just fine!

My dog was diagnosed with early mitral valve disease. He developed a small heart murmur that slightly increased in size over a year . I decided to give this a try for a year and was told at his annual follow up that there was no change in the size of the murmur. I can't definitively say that this supplement stopped the murmur from getting larger, but it's the only dietary and lifestyle change we made so I will be crossing my fingers and continuing use.

My chihuahua Diego was diagnosed with CHF about 6 years ago. He is on pimobendan and furosemide and has been doing good. Recently tho his cough came back, he was having a hard time sleeping and couldn’t get too excited without having coughing episode. I found this product in amazon and ever since I started giving it to him, half a capsule with dinner, he has improved so so much. His cough is essentially gone and he can sleep through the night. He has a lot more energy during the day as well and no side effects at all. Thank you for such a great product. Definitely recommend!!

My cat was diagnosed with HCM (his breed is predisposed). It's in a very low stage and does not currently need to be treated per his initial echo). He did have a heart murmur noted on his first exam and since using this, it's no longer detected. I will have to see how his next echo will go, but I will continue to use this product. I like that I can mix the capsule powder into his food, he does not seem to notice, and it's only once daily.

I purchased this item along with the probiotics powder. I started my 5 pound 6 year old chihuahua on this about two weeks ago. My dog has had issues for the past few years with his endurance such as walks for up to 15 mins and breathing issues and he tended to hack and cough after very short play time maybe after about 5 minutes of running through the house . He no longer is having difficulty breathing and is no longer hacking and coughing which was a big deal for me. He can now play and take walks for longer than 10 minutes and does not run out of breath at all. I am loving this product so far as it will be a staple in his diet now!

So I took my dog to her bi-annual check up last year and the vet came out and told me she noticed a subtle heart murmur and hasn't heard this before on her exam. This breed is definitely more prone to heart conditions so I knew her chances at some point were high with abnormalities with the heart. She is now 5 years old. I left the vet and immediately started researching good supplements for small breed heart support and came across this supplement for dogs. I ordered immediately and started her once a day with a capsule on her food. In about 2-3 weeks we noticed she started having more energy and was playful again like a puppy. Fast forward to her next Vet appointment which was a couple of weeks ago and I had a chest x-ray because she was coughing randomly over Christmas and would still do it here and there. I was worried her heart murmur had advanced so I took her in. After her appt and x-ray the vet called me and said her chest x-ray came out fine. Her heart was not enlarged and everything seemed to be functioning well with the heart. She had picked up a little weight since our last visit so she said sometimes the coughing can come from the weight gain and her being a smaller breed with her trachea. But even her trachea looked good on the film. Thank you Fera pets for your awesome supplements, I plan to keep her on the heart support the remainder of her life!!
