9 Best Supplements For Dog With Heart Murmur in 2026

Each chew contains 20 mg of CoQ10, along with taurine, L-carnitine, and AlaskOmega fish oil, ingredients that the manufacturer says support cardiovascular function, circulation, and cardiac muscle health. The salmon-flavored soft chew format makes it easy to give to dogs who accept fish flavors. This combination of ingredients targets heart health from several angles, as described in the product’s feature list.

The only flavor available is salmon, so dogs that dislike fish may not take it. There is no dosing guidance by weight on the label, so you will need to adjust the number of chews based on your dog’s size on your own. Compared to other heart supplements like VetriScience Extra Strength Healthy Heart Chews, which comes in chicken flavor, this Zesty Paws product offers a different taste option that may work better for some dogs. For owners seeking a supplement with CoQ10, taurine, and fish oil in a soft chew, this is a straightforward choice.

A 60-count container delivers roughly one month for a medium to large dog, so you will be reordering regularly. Compared to Zesty Paws Cardio Bites, which also packs taurine and CoQ10 but in a 90-count salmon chew, CARDIOMAX adds Hawthorn and Arginine for broader circulatory support. If your dog is picky about chew textures or you prefer a liquid supplement, Pet Wellbeing Young at Heart offers a liquid alternative, but it lacks the same amino acid lineup. For a vet-formulated all-in-one heart chew, this is a reasonable option to consider.

The 60-count bottle of chicken-flavored soft chews contains CoQ10, Carnitine, Taurine, and Hawthorn, ingredients listed in the product’s heart-support formula. The manufacturer states the chews are designed to promote healthy circulation, a strong heartbeat, normal blood pressure, strong heart muscles, and easier breathing. The taurine supplement is recommended for breeds including Cavalier King Charles Spaniels, Dobermans, Boxers, Golden Retrievers, Great Danes, and Poodles. The soft chews are chicken-flavored and described as easy to split, which can be convenient for adjusting portions.

The trade-off here is the count: at 60 chews per bottle, a large-breed dog on a daily regimen will run through it quickly compared to the 150-count OKKÖBI Heart Support Chews. If you prefer less frequent reordering, that larger bottle might suit your rhythm better. But if your dog needs the targeted blend and you don’t mind a shorter cycle between purchases, this formula delivers the key cardio nutrients as described.

The trade-off is that this formula skips CoQ10, an ingredient you’ll find in competitors like Zesty Paws Cardio Bites. If your vet has specifically recommended CoQ10 alongside Taurine and Carnitine, you may need to look elsewhere or add a separate supplement. The 60-count bottle means a daily-dosing dog will need a reorder in about two months if you give one chew per day, something to keep in mind for your subscription timing. That said, for a vet-formulated heart support chew that keeps the ingredient list straightforward, this is a practical option.

Each tablet packs 500 mg of taurine, a high dose that targets the amino acid often linked to canine heart health. Combined with 50 mg of L-Carnitine and 10 mg of CoQ10, this formula covers three core support angles in one chewable tablet. For owners managing a heart murmur diagnosis, the potency here means fewer tablets per day compared to lower-dose options, which can simplify daily routines. The chicken flavor helps with acceptance, a practical detail when a dog already has enough on its plate.

The catch is that a chewable tablet is not a soft chew. Dogs who refuse tablets or need a pill pocket may require a bit more work at serving time. The Zesty Paws Cardio Bites come in a salmon flavor, whereas PET LOL uses a chicken-flavored tablet.

A 150-count bottle of soft chews delivers taurine, CoQ10, and L-Carnitine in a chicken-flavored treat that skips the pill-hiding routine. That trio of amino acids and antioxidants is the same core blend many vet-recommended heart supplements use. But here it comes in a single-size formulation with no per-weight serving instructions, so you will need to estimate the right dose for a very small or very large dog. A supplement like Zesty Paws Cardio Bites adds Sea Buckthorn and AlaskOmega to its similar trio, while the OKKÖBI sticks to just those three ingredients in a larger 150-count bottle. If your dog refuses chicken or you want weight-specific dosing, this may not fit; for a straightforward, long-lasting heart support option, it is a practical choice.

A single-size formulation with no per-weight serving instructions means you’ll need to gauge the right amount for a very small or very large dog on your own. The Zesty Paws Cardio Bites offer a similar trio of ingredients but in a 90-count bottle, while the OKKÖBI gives you more chews per bottle. If your dog is picky about chicken or you want a formula tailored by weight, you might look elsewhere, but for straightforward, long-lasting heart support at a fair per-chew value, this is hard to beat.

Each soft chew delivers 500 mg of taurine and 250 mg of L-carnitine in a single serving, so you don’t have to measure powders or break capsules. The formula also includes CoQ10 and hawthorn berry, ingredients that appear in the product’s heart health support claim. The chicken-flavored soft chew format is designed for daily use, and the 180-count container offers a long-lasting supply. This makes it a practical option for owners who want a ready-to-give supplement without dealing with messy powders or capsules.

You’re locked into chicken flavor and a soft chew format, which won’t work for every dog. If your dog has a poultry sensitivity or simply refuses chicken-flavored treats, you’ll have to look elsewhere. And while 180 chews per container means you won’t run out quickly, the soft texture is what it is. For most owners looking for a straightforward daily heart support supplement, the four-ingredient approach and convenience make this a practical daily option worth trying.

This liquid supplement contains hawthorn and motherwort, as listed in the product name, and is NASC Certified, which indicates a quality manufacturing standard. The liquid form can be mixed into food for easy administration, which may be convenient for senior dogs. The formula is veterinarian-formulated, according to the Amazon title, and targets senior dogs for heart and circulation support. Owners looking for a simple herbal supplement without added amino acids or antioxidants may find this fits their needs.

Unlike heart supplements such as Zesty Paws Cardio Bites, which contain taurine, CoQ10, and L-carnitine, this product relies solely on herbs. That means it does not provide those specific nutrients, which some dogs may need based on veterinary advice. For a senior dog that only requires gentle support, this liquid offers a straightforward option, but it is not a substitute for targeted amino acid or CoQ10 supplementation.

One soft chew that covers both heart function and everyday calm means you’re not juggling two bottles at mealtime. Each piece delivers 150 mg taurine for heart muscle support, plus L-carnitine and CoQ10 for energy metabolism, alongside L-theanine and magnesium to take the edge off car rides or alone time. The chicken flavor and soft texture make it easy to give as a treat, so there’s no wrestling with pills or hiding powder in food. For owners who want a simple daily routine that addresses both cardiovascular and stress needs, this combo approach saves time without cutting corners on ingredients.

Dosing flexibility is the trade-off here. Dogs over 75 pounds need three chews per day, which runs the bottle down faster, about 40 days for a large dog versus four months for a small one. The Zesty Paws Cardio Bites focus solely on heart support, whereas this product adds a calming layer that can help dogs who get anxious during vet visits or thunderstorms. It’s a practical all-in-one for owners who value convenience and dual support over a single-nutrient approach.
