10 Best Heart Supplements For Dogs in 2026

Twenty milligrams of CoQ10 per chew, alongside Taurine, L-Carnitine, and AlaskOmega fish oil, gives this supplement a broad-spectrum approach to cardiovascular support. The salmon flavor helps with picky eaters, and the chewable format means you don’t have to hide a pill in peanut butter every morning. It’s a well-rounded daily option for owners who want a single chew that covers multiple heart-healthy bases without juggling separate bottles.

Each chew delivers 20 mg of CoQ10, a dose that supports normal cardiovascular function in dogs. If your dog refuses soft chews, the liquid Pet Wellbeing Young at Heart can be mixed into food instead. For most households, these 90 salmon-flavored chews provide a straightforward way to give Taurine, L-Carnitine, and AlaskOmega fish oil for heart support.

A 60-soft-chew container packs a veterinary-formulated blend of L-Taurine, L-Carnitine, CoQ10, Hawthorn, and Omega-3 fatty acids specifically aimed at dogs with heart murmurs, early valve concerns, or mild DCM. That combination of amino acids, antioxidants, and essential fatty acids targets circulation, heart muscle function, and oxidative stress in one daily chew. For owners whose breed or vet has flagged heart risks, this is the supplement that checks the most boxes on paper without requiring a separate pill organizer.

The 60-count container is a manageable size for daily dosing, but if you have a medium or large dog, you will need to reorder more frequently than with larger-count options. The soft chew format is generally easier for picky dogs than tablets, but there is no liquid alternative here. For a formula built around specific cardiac concerns and backed by NASC certification, this is a strong starting point.

The trade-off is that you only get one flavor choice here, chicken, so if your dog has a poultry sensitivity or prefers something else, you’re stuck. Compared to the Zesty Paws Cardio Bites, which come in salmon, VetriScience doesn’t offer a fish-based alternative. That said, for dogs who enjoy chicken, the soft chewy texture and strong scent make dosing straightforward. It’s a practical, no-fuss solution for daily heart support, especially if your dog already associates the chicken smell with something good.

Each chewable tablet packs 500mg taurine, 50mg L-carnitine, and 10mg CoQ10 into a single chicken-flavored dose, so you don’t need to juggle multiple bottles or supplements. That 3-in-1 formula covers the main heart-support bases: taurine for cardiac muscle function, L-carnitine for energy metabolism, and CoQ10 for antioxidant protection, without overcomplicating the daily routine. The 120-count bottle gives you a long stretch between refills, and the chewable shape works well for dogs that tolerate tablets. If your dog is picky about flavors, the chicken coating helps, and the ingredient list avoids common allergens like wheat, gluten, and soy.

The catch is that this product sticks to the three core ingredients and skips extras like EPA/DHA or hawthorn berry that some competitors include. For instance, CARDIOMAX Heart Support Soft Chews adds omega fatty acids for additional circulatory support, which might matter for dogs with known heart conditions. If your dog needs a broader nutritional profile, you might look elsewhere, but for a no-fuss, concentrated 3-in-1 approach, this covers the essentials cleanly.

This liquid supplement is formulated by a veterinarian and NASC-certified, using hawthorn and motherwort to support cardiovascular wellness in senior dogs. The liquid format is designed for rapid absorption compared to pills or powders, and it can be mixed with meals for easy administration. It targets age-appropriate cardiovascular wellness for mature dogs experiencing age-related changes, supporting healthy circulation and heart function as dogs age gracefully.

The formula relies on traditional herbs rather than ingredients like taurine, CoQ10, or L-carnitine found in some other supplements. This makes it a suitable choice for general senior heart maintenance, but if your vet has recommended specific nutrients for a diagnosed condition, you may need a supplement with those components. For a healthy senior dog needing daily cardiovascular support, this liquid offers a straightforward herbal option.

Four active ingredients, taurine, L-carnitine, CoQ10, and hawthorn berry, make up this chew’s formula for cardiovascular support. The 500 mg of taurine per chew is a notable amount, and the 180-count bottle provides a supply that lasts for daily use. This combination suits owners who want a supplement with multiple ingredients for a dog’s heart health, especially for breeds or ages that may benefit from such support.

Each chew packs 500mg of taurine, 250mg of L-carnitine, CoQ10, and hawthorn berry, so you’re giving your dog a complete cardiovascular blend in one soft treat. The chicken liver powder makes the flavor appealing enough that even picky eaters tend to take it willingly, turning a daily supplement into something they look forward to. For dogs that can have chicken, this is a straightforward way to support heart function and energy without fussing with powders or pills.

For a dog with a known breed risk, an early murmur, or simply entering its senior years, this chew offers a science-backed foundation rather than a hope-and-prayer approach.

The chicken-flavor delivery means you skip the powder-mixing hassle and just hand over a treat your dog actually wants to eat. That matters because daily compliance is the whole game with heart supplements, if they won’t take it, the taurine, CoQ10, and L-Carnitine blend does nothing. This makes it a natural fit for owners of picky eaters or multi-dog households where you need something quick that everyone will scarf down without a fight.

You’re locked into that one flavor, so if your dog turns up their nose at chicken, you’re out of luck. Compared to Zesty Paws Cardio Bites, which offers a salmon option, MULTIBITES gives you less flexibility on taste. For most dogs, that chicken flavor works.

The formula uses clinically studied L-Carnitine, which supports heart health, energy, and weight management, along with Hawthorn Berry, CoQ10, and Taurine for circulation and cardiovascular function. It comes in a bacon-flavored soft chew without gluten, soy, or shellfish, making it suitable for dogs with those sensitivities. Manufactured in the United States under Good Manufacturing Practices and with NASC membership, it offers a quality-controlled option for owners focused on heart and weight support in one treat.

For dogs up to 75 pounds, the serving size is two chews per day, so a 90-count container provides a supply that lasts more than a month. Compared to some other heart chews on the market, this formula includes Hawthorn Berry alongside Taurine and CoQ10, which supports circulation. Owners who want a bacon-flavored chew that focuses on weight management and heart health will find this a practical option.

A 0.1-pound bottle of powdered supplement built around selenium and bovine liver makes this a targeted whole-food approach to canine heart health, not a catch-all chew.

This is a one-note player in a guide full of multi-ingredient chews. Most competitors pack taurine, CoQ10, L-carnitine, and omega-3s into a single soft chew, while Canine Cardiac Support delivers selenium and little else. If your dog already gets those other nutrients from food or a separate supplement, this powder is a clean way to add selenium without overlap. But if you want an all-in-one heart support chew you can toss in a bowl and walk away, something like Zesty Paws Cardio Bites offers a broader ingredient list in a ready-to-eat format. This one requires measuring and mixing, and the small bottle means more frequent reordering for larger dogs.
