10 Best Low Sodium Dog Treats For Heart Murmur in 2026

A low sodium count helps maintain heart and kidney health, and the low calorie profile supports ideal weight management. Hill’s Prescription Diet Crunchy Dog Treats are formulated by Hill’s own nutritionists and veterinarians, so the balance of ingredients isn’t guesswork. These are made in the USA with global ingredients you can trust, giving you a reliable option when your dog needs every bite to count.

The most important thing to know is that these treats are formulated by Hill’s nutritionists and veterinarians specifically for dogs under veterinary care, so they’re not a casual snack you grab without a vet’s guidance. They’re low sodium to help maintain heart and kidney health, and they pair with a range of Prescription Diet lines like b/d, c/d, g/d, h/d, i/d Low Fat, j/d, k/d, k/d Mobility, r/d, and w/d. By comparison, Mattie’s Treats Mini Treats also focus on low sodium, but Hill’s compatibility with multiple prescription diets means you have more flexibility if your dog’s needs shift. If your pup is already on a Hill’s prescription food, these treats are a straightforward match.

A 10 oz box of heart-shaped crunchy treats formulated with low sodium, low protein, and low phosphorus means these are built for dogs with specific dietary restrictions tied to kidney conditions. That trifecta of controlled nutrients makes them a rare find for small-breed pups who need treats that won’t work against their kidney health needs. The six-ingredient list, light rye flour, tapioca flour, pure pumpkin, cinnamon, fish oil, and canola oil, keeps things simple and avoids the long chemical laundry list common in prescription-style options.

The trade-off is portion size: at 10 ounces, this box goes faster than the 16 oz Mattie’s Treats Original bag. That is especially true if you have more than one small dog or a dog who earns multiple training rewards per day. Compared to the Hill’s Prescription Diet Crunchy Dog Treats, which are also designed for dietary management, Mattie’s Treats gives you a low protein and phosphorus profile without requiring a prescription. If your small dog needs a daily treat that respects kidney limits, this is the one to grab.

A 16-ounce box of crunchy treats that are low in sodium, protein, and phosphorus means you can reward a dog managing a kidney condition without throwing off its carefully managed diet. The six-ingredient list, light rye flour, tapioca flour, pure pumpkin, cinnamon, fish oil, and canola oil, keeps things simple. The pumpkin and cinnamon give them a flavor most dogs don’t turn their noses up at. These treats are designed to complement a kidney-friendly diet, and the heart shape is a nice touch when you’re trying to make every moment count.

These are crunchy biscuits, not soft chews. If your dog has dental issues or prefers something chewy, you’ll need to look elsewhere. The fish oil and canola oil also means this isn’t a single-ingredient or grain-free option, which some owners avoid. Compared to the prescription diet crunchy treats from Hill’s, Mattie’s offers a low-sodium, low-protein treat without requiring a prescription, while Hill’s is the #1 Veterinarian Recommended brand.

Freeze-dried beef liver with nothing else added means you know exactly what your dog is getting, no preservatives, fillers, or mystery ingredients. For a dog with a heart murmur, keeping sodium low is a priority, and these treats deliver that naturally while also packing iron, vitamin D, and calcium for overall bone and muscle health. The crunchy texture from freeze-drying makes them satisfying to chew, and the single-ingredient simplicity is a relief if your dog has a sensitive stomach or you’re trying to avoid triggers.

This treat is pure beef liver and nothing else, so if you want added heart-support ingredients like taurine or omega-3s, you’d need a different product. But for owners focused on keeping sodium low without a long ingredient list, Ruff Greens Tidbits delivers exactly that, and the freeze-drying locks in the liver’s natural vitamins and minerals. It’s a simple, clean option for those who prefer single-ingredient treats over fortified ones.

With 27% protein, real chicken first, and a grain-free recipe that includes taurine plus omega-3s (EPA/DHA), these chews target cardiovascular function directly rather than just providing a general treat. That focus makes them a practical option for owners who want a reward that also supports heart health, especially for adult and senior dogs. There are no artificial preservatives, colors, or fillers, so you’re giving something that delivers targeted nutrition.

This isn’t a low-sodium treat, it’s designed for heart support with a broader nutrient profile. If your vet has you watching sodium and phosphorus closely for a heart condition, Mattie’s Treats Mini Treats are formulated specifically for that. But if your dog’s main need is added taurine and omega-3s in a soft, easy-to-chew reward, this fills that gap well.

Zero added salt and a grain-free recipe built around beef and sweet potato make these a straightforward pick when you’re watching sodium. The sweet potato provides potassium, which is listed as a nutrient that promotes healthy heart function, and the treats skip the artificial dyes, flavors, and preservatives that clutter many bags on the shelf. That kind of clean ingredient list can be appealing for anyone prioritizing natural snacks.

These aren’t a prescription or targeted heart-support formula like the Hill’s Prescription Diet Crunchy Dog Treats. They’re a general healthy snack with a heart-friendly profile, not a therapeutic tool. If your vet wants a treat that actively delivers taurine or CoQ10, you’d need something like the Wellix Healthy Taurine Dog Treats. But if your priority is simply keeping sodium at zero while rewarding your dog with something natural, these fillets do exactly that without pretending to be more.

A single-ingredient beef liver treat with naturally low sodium means you can reward your dog without worrying about hidden salt or fillers. Freeze-drying locks in the iron, vitamin D, and calcium from the liver itself, so every crunchy piece delivers nutrition that supports bone strength and muscle health. For a dog that needs a clean, low-sodium option, this is about as straightforward as a treat gets: one recognizable ingredient, no preservatives, and a sodium level that won’t work against balanced hydration. It suits owners who want a straightforward, protein-packed reward they can feel good about giving daily or during training sessions.

You get exactly one flavor and one texture here. If your dog turns up their nose at liver or has trouble with crunchy bites, this bag won’t stretch far. Compared to Mattie’s Treats Mini Treats, which offer a low-protein, low-phosphorus, low-sodium formula, Ruff Greens Tidbits focus entirely on simplicity and nutrient density rather than a tailored medical profile. That makes it a great pick for dogs that need low sodium first and foremost, but less ideal if you’re also managing multiple dietary restrictions at once.

The most important thing to know is that these are low-sodium, low-protein soft chews made from real apples and carrots with no animal ingredients at all. That matters if your dog needs a restricted diet, as they contain no corn, wheat, or soy. They are also gluten-free and hypoallergenic, which helps if your dog has a sensitive stomach or allergies. The soft, chewy texture is a practical bonus for senior dogs or those with missing teeth, since the product is described as best for dogs without teeth and perfect for mature dogs with dental issues.

These are entirely plant-based, so they won’t deliver the meaty flavor many dogs expect from a treat. If your dog turns up their nose at fruit and veggie snacks, you might have better luck with something like the low-sodium, low-protein Mattie’s Treats Mini Treats. Still, for owners who want a clean, vegan option that checks the low-sodium and low-protein boxes without any corn, wheat, or soy, these are a straightforward fit.

Added taurine is the key feature here, an amino acid that supports normal cardiovascular function and energy levels, making this a targeted option for dogs needing heart support. The peanut butter and apple ingredients keep it appealing, and the formula avoids meat meals, artificial preservatives, and common allergens like wheat, soy, or dairy. That clean ingredient profile is a plus for owners who want to avoid fillers and byproducts. Formulated by veterinary nutritionists and made in the USA, it adds a layer of confidence for dogs with heart concerns.

Formulated by veterinary nutritionists, these crunchy cookies deliver 8.8 ounces of peanut butter flavor with added taurine to support normal cardiovascular function and overall vitality. The recipe avoids common allergens like wheat, soy, and dairy, making them gentle for dogs with sensitive stomachs. Owners report the clean ingredient list, no meat meals, artificial preservatives, or unnecessary additives, gives them confidence in what they’re feeding. At 0.6 pounds, the bag is lightweight enough to toss into a purse or backpack for on-the-go rewards.

At just 6.7 calories per piece and fortified with 5% taurine plus CoQ10, this biscuit targets cardiac function without piling on extra calories during training. The real chicken and pumpkin give it a flavor most dogs find hard to resist, and the crunchy texture doubles as a light teeth-scraping snack. For owners managing a heart murmur diagnosis, the taurine and CoQ10 combination is the standout feature here, both nutrients directly support steady heart function, which is exactly what you want in a daily reward.

This treat contains chicken, so it is not suitable for dogs with poultry allergies. Compared to Mattie’s Treats Mini Treats, which are explicitly low-protein and low-phosphorus, Wellix focuses more on active nutrient support with taurine and CoQ10. It is a better fit if your priority is getting taurine into every bite rather than restricting protein or phosphorus.
