Did you know that over 10% of animals have some form of cardiovascular disease; or that congestive heart failure (mitral valve issues) affect 20-40% of dogs? The cardiovascular system of your dog is made up of the heart, artery, and veins. The three most common heart health issues with dogs are chronic heart failure, cardiomyopathy, and heart failure. If your dog is diagnosed with heart health issues, it will be a condition that they may have to live with for the rest of their lives.  

You can, however, help support your pet’s heart function, vitality and overall well-being with NHV's heart health herbal supplement, “Hearty Heart”. This vet approved, vet formulated all natural herbal supplement is both gentle and powerful. Hearty Heart is formulated with herbs that provide support for your dog's heart, their valves, and their pulmonary system. This combination of botanicals may improve blood flow, ease coughing, improve breathing, and help with appetite; it will also aid with other symptoms of dog heart conditions like weakness, restlessness, and anxiety.

My 6 y.o. Westie was diagnosed with heart murmur, so I've started him on hearty heart, he seems to have more energy and very playful. He doesn't mind the taste of it, which makes it easier for me to administer. Thank u NHV *

My dog has congestive heart failure and this medication has helped relieve some of his coughing. The prescription meds he was on before only made it worse. This seems to be the only thing that is helping him. *

Monkey, a 9 year old black mouth cur, has been using this product for almost two years after being diagnosed with congestive heart failure. I mix it in with her food twice a day. She was given six months to live when she was diagnosed. After a one year check up, her doctor told me to keep doing whatever I was doing because her condition hadn't seemed to deteriorate. One week ago, she had her two year check up and is still going strong. She also takes dandelion tincture. milk thistle tincture, fish oil and VetriScience Cardio Strength. I would highly recommend this product. *

My sweet black & white ShihTzu Jasper was diagnosed with a heart murmur several years ago. A friend told me about Hearty Heart & I've been giving it to Jasper ever since. He is nearly 13 years old now and his murmur is barely discernible by his vet. I attribute it to Hearty Heart, along with regular exercise and a healthy diet. Thank you for this wonderful product. *

Over a year ago my Female Dachshund was diagnosed with an enlarged Heart, congestive heart failure, a heart murmur, fluid in the lungs and high blood pressure. My Vet recommended Hearty Heart for her and it's been a life saver!! I started using NHV's Turmeric and Hearty Heart combo together a few months ago which has greatly helped to reduce her diarretic medication with regard to the fluid in her lungs and the high blood pressure. Only wish it was cheaper but she really needs it. I love my Tinkerbell *

Hi....and WOW!! I only ordered Foxy's repeat order on Sunday afternoon and it arrived in France just now, les than two working days!! That is amazing service. I hate having to pay DHL charges but at least they are reliable and your service is just great. Oh...and Foxy, my beloved fox terrier/spaniel cross, says thank you, too. At almost 14 and seeming to be on his last legs twelve months ago after being told his heart murmur had deteriorated, he is now like a puppy again since he was introduced to your Hearty Heart Drops. You recommended 1ml twice a day and it has been a miraculous turnaround. Thank you so much. I heartily (pun intended!) recommend this product as a natural alternative to veterinary chemical prescriptions. Best regards Pauline *

My 11 1/2 year old Maltese went in last year for her yearly shots and her vet tells me, oh ~ did you know she has a heart murmur? Well, NO I didn't know till now. I ask for blood work and an x-ray to be done on my sweet Molly. Blood work came back good and x-ray shows the heart murmur enlarge. He started her on 2 meds, but a few months later I thought I lost her, she had fainted, I took her back in to the vet, he increased one of her meds but she kept having that ugly cough at night, and we both lost a lot of sleepless nights. I recently took her back and he prescribed another medication. The 1st month was fine until now she seen to have gotten worse with the coughing. I was browsing the internet and came across this website. After reading all the reviews I got very excited and order one, it came today and gave Molly her first dose, I will update later. I'm just praying with all my 💜 it will help my little baby girl, I love her so much and it breaks my 💔To hear her cough🐶🐾🐾✝️ *

sunyu - korea | June 15, 2017

I am growing a poodle on a 3.5kg fourteen-year-old. He was diagnosed with Cushing 's in February 2016 and his blood pressure had risen to 180. I heard that the heart sound is normal, but the heart size is a little big. So I ordered HEARTY-HEART. About two months later, he was told that his blood pressure went down to 140 in a hospital checkup. And I was diagnosed that the heartbeat was still normal. I do not know if this is the product, but I am very satisfied. I currently buy two bottles. I hope you have good news from this regular checkup. *

I had wanted to put Joey (turning 14 in August) on Hearty Heart last Fall but due to his cough medicine for his trachea collapse we could not. It was very hard to distinguish his trachea cough from his heart cough, however starting in March it appeared his cough medicine was no longer working. After consulting with his regular vet, she agreed to discontinue his cough medicine which then made using Hearty Heart an option. He took his first dose on a March 30th and he began to feel better almost immediately, He continues to take his regular meds of [**pharmaceutical names removed] but he has quality of life back again. His energy is like that of a young dog but we still have to try to keep him calm due to his trachea. He is no longer restless at night and his anxiety has definitely decreased which also helps his trachea. Thank you NHV for all of your products, your help and your patience. *

It has been just 2 weeks since I've given Hearty-Heart to my 13 year old doggie. He has suffered from Stage C of Heart failure for over an year so that his cough could been usually observed. But after we started this remedy, he rarely coughs and looks so good and comfortable. I hope the more he takes, the better. *

We've had great results with Heart-Heart! Our (approximately) 12-to-13 year-old rescue Border Collie Jake was diagnosed with a Grade 3 systolic heart murmur during his annual check-up in October of 2016. I researched quite a few options of treatment, and decided to give NHV's Hearty-Heart a try. Within a short time, Jake seemed to be panting less, and his cough almost completely disappeared! He has good energy, and rarely skips meals now. His back-end muscle weakness is noticeably better, too. I truly believe NHV gets the credit, because the only time it seems we hear him cough is if we've missed a dose of Hearty-Heart. The first 6 years of his life were rough from what we know - chained outside in northern Illinois with little shelter and heaven-only-knows what kind of food and care. His foster Mom nursed him back to better health, and we've now had him almost 6 years. He's big for a BC, averaging around 55 pounds. He gets regular veterinary care and great food. We're looking forward to his next check-up to see if we've held the murmur at 3, or if maybe even reversed it! Thanks so much, NHV! Judy, Doug and Jake Reynolds *

I have used hearty heart for the last 2 years as part of the protocol for my 14 year old dog, Scout, who was diagnosed with heart disease. These products were recommended to be used with his prescriptions by his vet and I believe they have really helped him. Would definitely recommend! *

Brent - Brooklyn, NY | January 18, 2017

I give this to my 13.5 year old Boston Terrier twice a day who was diagnosed with CHF and arrhythmia 6 months ago. Her most worrisome symptom from heart disease was syncope. Late at night Asta would fall over, arch her back, moan loudly in distress, blank out, then pee on herself. These episodes are significantly less severe and frequent since hearty heart. Instead of every 2-3 wks she's only had two attacks in the past 3 months. One of the attacks also coincided with missing her evening dose. Asta has also been on [**pharmaceutical names removed] prior to hearty heart but those meds didn't seem to have the same positive results. *

Jessica J. - Citrus Heights, Ca | September 3, 2016

I can't even tell you how incredible this stuff works. My dog was diagnosed with a heart murmur A few years ago & because of his age they told me he wouldn't live long. Well it's been 2 years since his diagnosis & he's still going strong but I could tell he was starting to feel the effects. His cough was getting worse, he was increasingly uncomfortable at night & pacing,breathing heavy especially after getting up or with a little bit of activity. It hurt me to see him that way & I didn't want to take him to the vet where they would tell me it's time to let him go. So I found this stuff, read the reviews & it is EVERYTHING everyone says it is. My sweet oldie is not struggling to breathe anymore, he doesn't pace at night & the cough is nearly gone. Not to mention he has perked up & is so much more alert. This amazing stuff gave me my dog back & I hope to have more good years with the best dog on this planet! Thank you!!!! *

cmelliott - Philadelphia, Pa | March 22, 2016

I have an older shepherd who'd been suffering with all the symptoms of congestive heart failure (coughing, low energy, muscle weakness) and I thought I'd try this (I am not usually in favor of pharmaceutical drugs since they fix one problem while causing another usually). Anyway, this has been a godsend for my Charley. He had gotten so bad he couldn't go for a walk and could barely get down my front steps to pee. With him only on Hearty Heart for 1 month, he's made amazing progress. He seems happy again, eating well again, can take normal walks again (albeit slow), and his hacking, heavy breathing has reduced greatly. I give the herbs to him in a bowl of milk with a raw egg beat into it twice a day or more if he needs it. This combination has brought my dog renewed life and bought us more time with him and I'm eternally grateful for coming upon this product. Shipping was super fast too (got to me in 2 days). *

Sharon - Montana | August 20, 2015

This product has tremendously helped my 13 1/2 yr old poodle with her screeching cough. She was diagnosed with congestive heart failure and her enlarged heart irritated her trachea. When the vet put her on a narcotic cough medicine, she vomited for 3 days. SInce I already was using Hearty Heart, (which by the way has my little dog acting playful and happy again), I decided to return to your site to see if something could help her persistent cough. Thankfully, I found this respiratory aid/cough medicine to try. Your staff thought the respiratory aid would help her trachea irritation. She has been on this respiratory aid for 3 weeks and I see a huge improvement. We now all have peaceful nights of sleep without coughing spells! *

Rocket & Emily - Kansas | April 23, 2015

I have two older dogs. Rocket is 13 and weighs 80 lbs. Emily is 15 and weighs 15 lbs. Rocket started having fainting spells, which is known in the boxer breed. He is part collie and part boxer. After taking him to the vet, I started looking for some home remedies or herbal remedies for Rocket. Emily is very overweight for her breed and has developed a cough with heavy breathing after excertion. So when I came across Hearty Heart, I thought this would be good for both dogs. I orderd some and started giving it to both of them. Their enegry level went up, they are both eating and drinking on a regular basis and seem to be doing very well. I am very pleased with Hearty Heart and will be ordering more. I would and will highly recommend this product to my friends and family!! *

Oscar - USA | April 16, 2015

My 9 year old Cavalier King Charles Spaniel developed a heart murmur 1 year ago. He started having a cough related to his heart being enlarged and pressing on his trachea. After switching vets and being told he had a Stage 4-5 heart murmur (but not CHF) he put him on a low dose of [**pharmaceutical names removed] also telling me to give him [**pharmaceutical name removed] if he was coughing a lot. Oscar was still occasionally coughing so I started looking for other natural alternatives online. I came across Hearty Heart I purchased it, then decided I would take it to my vet (assuming he would tell me it wouldn't really help). He looked at the bottle & ingredients and encouraged me to try it along with his current prescription drugs, incidentally telling me he wasn't really in favor of drugs (he's European) and was already giving him much lower doses than he should actually receive. It's been a little over a month and Oscar is rarely coughing (I suddenly realized I haven't given him a cough tablet in over 2 weeks) and is energetic and back to his normal self. Very pleased with this product! Highly recommend (and also recommend consulting with your vet prior to usage). *

Millie - Ohio | May 16, 2013

Millie is a 12 year old Chinese Crested. In January of 2012 she developed an awful cough. she was restless, her breathing was labored and she kept us up all night coughing & pacing . The vet said it was her heart. He tried 2 different medications but they did not help. So, I ordered Hearty Heart and WOW, within a couple of weeks NO more coughing. She is back to her normal self. She acts like she did 5 years ago, she plays with the other dogs and sleeps through the night.I do not have any trouble giving it to her. First thing when she gets up, she goes to the refrigerator sits and waits for me to give it to her. It is like she knows that is what has made her better. I would recommend this to anyone who has a dog with heart problems . THANK YOU SO MUCH FOR GIVING US OUR MILLIE BACK! *

I use Hearty Heart 2 times a day for my 8 yr old Chorkie with stage 5 heart murmur. It took a week to kick in but when it did he lost his belly bloat and became alot more alert and active! He runs, plays and acts like a healthier pet! After talking to my vet about 'human' heart meds for his final stages I refused to pump chemicals into his tiny body. I'm very happy with the results and Peanuts seems to be too! He's a very picky eater and doesnt mind the flavor at all! I cant wait for his next check up! Thank you Hearty Heart!!! *

S. Church - Connecticut | May 16, 2013

My 10 year old mini schnauzer was diagnosed with a heart murmur last year of a 3-4 (on the scale of 1-6) Six being the worst. Then two months ago the same vet found that the murmur had worsened to a level 5-6. I started him on Hearty Heart, which he has been on for 7 weeks, with vitamin E, raw meat and veggie diet. 
Yesterday I took him to the vet for a check up. His heart is much stronger and the murmur is at a 4. I am so grateful. *
