A heart murmur diagnosis changes how you shop for everything your dog eats, treats included. Regular biscuits can carry more sodium than a cardiac diet allows, and sneaking them anyway quietly undoes the work your vet’s plan is doing. This shortlist focuses on low-sodium, low-protein, and heart-supportive options that fit real life: training rewards, pill hiders, senior-dog chews, and soft bites for older teeth. Each pick below was chosen for ingredient transparency and cardiac-friendly formulation, so you can reward good behavior without second-guessing every crunch.

More Details On Our Top Picks
This is the only option here designed specifically around aging hearts rather than adapted to them. The soft-chew format suits dogs five years and up of any breed, and the 60-count tub covers roughly a month of daily dosing depending on your dog’s weight.
The ingredient list reads like a cardiology supplement: taurine and acetyl-L-carnitine support heart muscle, while Hawthorne berry, dandelion, bilberry extracts, egg albumin, and coenzyme Q10 round out the cardiovascular picture. Unlike the plain snack picks further down, this one doubles as a supplement, which matters when every calorie needs a job.
Strong Points
- Vet-recommended formula aimed squarely at senior cardiac health
- Taurine plus CoQ10 support normal heart rhythm and circulation
- Corn, soy, and wheat free, with no artificial colors or preservatives
- Made in the USA with natural ingredients you can verify on the label
- Soft texture works for older dogs with dental wear
Things To Consider
- Serving amounts scale with body weight, so large breeds burn through the tub faster than the label suggests
- Owners commonly report the chews dry out once opened, so reseal the container tightly between doses
Key Specs
Who It Suits Best
Senior dogs whose vets want daily cardiac support built into a treat they’ll actually take without fuss.
Where A Sibling Pick Shines
Dogs needing a pure low-calorie biscuit alongside a prescription food will get more mileage from Hill’s Prescription Diet Original Crunchy Dog Treats instead.
Where the Ark Naturals chews add supplements, this jerky keeps things simple: Alaskan salmon baked into strips, nothing wheat-based anywhere in the bag. Fish-first treats bring omega-3 and omega-6 fatty acids, fats linked in general canine nutrition to skin, coat, joint, brain, and cardiovascular function.
In practice, the strips tear easily by hand, which makes portioning simple for small dogs and quick for training sessions. At six ounces a bag, it’s a modest supply, though multi-bag packs exist if your dog takes to it.
What We Like
- Single animal protein from Alaskan salmon keeps the ingredient list short
- Omega fatty acids support coat condition alongside general wellness
- Wheat-free recipe suits dogs with grain sensitivities
- Tears cleanly for controlled portions during training
Worth Noting
- Jerky-style treats are moisture-rich, so the bag should be sealed well and used within a few weeks of opening to avoid spoilage
- The six-ounce size runs out quickly in multi-dog homes
Made For
Dogs of any size whose owners want a fish-based, grain-free reward with a short, recognizable ingredient list.
Consider Something Else When
A dog needing strict protein restriction fits the Kidney Restore Bacon Flavor Low Protein Dog Treats better, since salmon jerky carries meaningful protein per strip.
For dogs already eating a Hill’s Prescription Diet food, these bone-shaped biscuits solve a real problem: rewarding a dog on a therapeutic diet without breaking that diet. They’re formulated low in calories, protein, sodium, and phosphorus, with added fiber, which lines up neatly with cardiac and renal feeding plans alike.
The crunchy texture also gives some mild chewing satisfaction that softer picks like the Blue Buffalo bars don’t provide. Available in an 11-ounce single bag or a six-pack, sizing flexibility is a quiet advantage for households that go through biscuits fast.
Highlights
- Deliberately low in sodium, phosphorus, protein, and calories
- Designed to complement Prescription Diet foods without undermining them
- High fiber content supports satiety between meals
- Crunchy biscuit format doubles as light dental engagement
Small Caveats
- It’s a therapeutic product, so it’s worth confirming with your vet that it matches your dog’s specific prescription plan before adding it to the routine
- Some owners report the biscuits crumble at the bottom of the bag, leaving dust rather than whole pieces
At A Glance
Right Fit For
Adult dogs on vet-directed prescription foods whose owners need a compliant reward for training and medication time.
Not Your Match When
A healthy senior dog without a prescription diet gets better value from the Jinx salmon bone broth biscuits, which offer similar crunch with broader everyday appeal.
Training a dog on a sodium-restricted diet usually means choosing between compliance and motivation. These chewy sticks split the difference: USA beef as the first ingredient, carrot for easy digestion, and no added salt or sugar anywhere in the recipe. Around 25% protein gives them real reward value without the salt load of typical jerky.
The stick format snaps into smaller pieces, so one stick stretches across several repetitions. Compared with the Carolina Pets salmon jerky, this one leans meatier and chewier, which tends to hold attention longer in distracting environments like parks.
Reasons To Buy
- Zero added salt or sugar, rare in the jerky category
- Five limited ingredients keep the label easy to audit
- No corn, soy, wheat, artificial colors, or flavors
- Chewy texture occupies dogs longer than a crisp biscuit
Softer Spots
- The four-ounce pouch is small; heavy trainers may find themselves reordering often
- Chewy sticks can stick together in warm weather, so cool, sealed storage keeps them separate
- Beef is a common allergen, worth ruling out first for itch-prone dogs
Quick Facts
Who Should Grab It
Owners running frequent training sessions who need a high-value, salt-free motivator that fits in a pocket.
Swap It Out When
Dogs with suspected beef sensitivities do better on the PETIPET plant-based fruit treats, which skip animal protein entirely.
Older dogs with dental trouble often refuse hard biscuits outright, and that’s where this soft-baked bar earns its spot. Real chicken and apple give it a homemade-bakery aroma that picky eaters tend to respond to, and the tender texture means no crunching required.
It sits between the supplement-focused Ark Naturals chews and the plain jerky options: a genuine treat, not a therapy product. Nine-ounce bags come singly or in multi-packs, and the flavor range extends to chicken with coconut or mixed berries if your dog tires of one variety.
Bright Spots
- Soft-baked texture suits seniors and dogs with missing teeth
- Real chicken and apple deliver aroma that wins over fussy eaters
- Multiple flavor variants prevent treat boredom
Points To Note
- Soft treats hold moisture, so an unsealed bag can stale within days; a clip or airtight bin solves it
- Sodium content isn’t highlighted as a formulation priority, so check the guaranteed analysis against your vet’s limits
Whose Shelf It Belongs On
Households with senior dogs or dental-sensitive pups who still deserve a proper treat moment after pills and vet visits.
Look Elsewhere When
Strict sodium ceilings call for the Hill’s Prescription Diet Original Crunchy Dog Treats, which publish their low-sodium intent right in the formulation.
Multi-dog homes burn through treats, and this one-pound box of oven-baked biscuits is built for that pace. Real salmon and bone broth lead the ingredient list, giving the crunch a savory depth that cheaper grain-forward biscuits lack, and everything in the recipe is all-natural by the brand’s own selection standards.
Against the six-ounce Carolina Pets jerky, you’re trading some omega density for volume and shelf stability. A dry biscuit survives a week in the treat jar without fuss, which matters when three dogs are lining up at the same cupboard.
Plus Points
- Salmon and bone broth as first ingredients, not fillers
- One-pound format outlasts most boutique treat bags
- Oven-baked crunch holds up well in storage jars
- All-natural ingredient approach across the line
Room For Improvement
- Sodium isn’t positioned as a restricted-nutrient feature, so compare the guaranteed analysis with your dog’s limits before committing
- Hard texture excludes dogs with significant dental disease
Details At A Glance
Best Suited To
Healthy adult dogs in busy households that need an affordable, protein-first everyday biscuit in bulk.
Another Choice May Suit
Dogs with confirmed cardiac sodium caps belong on the Hill’s Prescription Diet Original Crunchy Dog Treats, where low sodium is engineered in rather than incidental.
Heart and kidney diets overlap more than most owners expect, since both restrict protein and sodium. These renal-friendly treats were built for that intersection: deliberately low protein, fortified with vitamins C, E, and B-complex, and flavored like bacon so the restriction doesn’t feel like punishment to your dog.
That bacon note is doing heavy lifting. Dogs on long-term therapeutic diets commonly lose interest in bland food, and owners report this one keeps enthusiasm alive through months of pill-hiding and training. Size options run from half a pound to larger multi-pound bags.
Standout Traits
- Low protein formulation aligned with renal and cardiac restrictions
- Added vitamins C, E, and B-complex support overall nutrition
- Bacon flavor maintains interest where plain therapeutic treats fail
Honest Caveats
- Flavoring means a longer ingredient list than single-protein jerky options, worth reviewing against allergy concerns
- Smaller bags cost more per ounce, so the larger formats make sense for ongoing daily use
- Some owners note the pieces vary slightly in size, requiring eyeballed portion control
The Right Fit
Dogs juggling both kidney and heart diagnoses whose treat options have shrunk to almost nothing.
Reach For A Different Pick When
A dog needing joint omega support without protein limits fits the Carolina Pets Oven Baked Salmon Jerky better, since fish fats come standard there.
This is the most explicitly cardiac-aligned snack on the list: the brand states its treats are low sodium and low protein outright, made from real apples and carrots with human-grade handling. No corn, wheat, soy, fillers, or processing aids appear anywhere, and the recipe is hypoallergenic and gluten-free by design.
Production happens in small batches at a human-grade facility in the USA, which shows in the soft, fruit-forward texture. A banana-strawberry variant exists for rotation. Against the meat-based picks above, you give up prey-drive appeal and gain predictability for allergic or sensitive stomachs.
Upsides
- Explicitly low sodium and low protein, stated by the maker
- Hypoallergenic and gluten-free for reactive dogs
- Real fruit and vegetables, human-grade facility, small batches
- No corn, wheat, soy, or processing aids
- Soft chewable texture works for all ages
Minor Gripes
- Plant-based treats rarely match meat aromas for motivation, so extremely food-driven dogs may rank it lower
- Soft fruit-based pieces can dry or firm up over time, so finish the pack promptly after opening
Feature Rundown
Built With In Mind
Allergy-prone dogs on cardiac or renal diets whose owners want every restriction addressed in a single treat.
Skip It When
A high-drive dog in serious training mode will work harder for the Bocce’s Bakery Beef & Carrot Jerky Sticks, which trade plant-based caution for meaty pull.
What Matters Most Before Choosing Low Sodium Dog Treats For Heart Murmur
Read The Guaranteed Analysis First
The guaranteed analysis panel lists minimum protein and fat plus maximum fiber and moisture, and sodium appears on many premium labels. Compare that number against whatever ceiling your vet set. A treat marketed as “natural” can still carry more salt than a cardiac diet tolerates, so the panel beats the front of the bag every time.
Match Texture To Your Dog’s Mouth
Seniors with worn teeth do better with soft chews like the Blue Buffalo bars or Ark Naturals chews, while younger dogs enjoy the crunch of Jinx biscuits. Texture also affects portioning: jerky tears, biscuits snap, soft bars cut with a knife. Choose the format that lets you control serving size precisely.
Decide Between Treat And Supplement
Products like the Ark Naturals chews deliver active nutrients such as taurine and CoQ10, while plain snacks simply avoid harm. Both roles matter, but they aren’t interchangeable, and doubling up without checking totals can overshoot your vet’s targets.
Confirm Compatibility With Prescriptions
Dogs on Hill’s Prescription Diet foods should stick with matching treats, since mixing brands can dilute a carefully balanced plan. A quick message to your veterinary team settles it.
Key Considerations Across These Picks
Traps First Timers Fall Into
The most common mistake is trusting marketing language instead of the analysis panel, since “healthy” and “heart healthy” carry no legal definition on pet treats. Another frequent slip is ignoring serving size math: a generous handful of even a compliant treat can push daily sodium past safe levels. Portion everything, and log it alongside meals for the first few weeks.
What Separates Premium From Basic
Higher-tier options justify their cost through targeted formulation: measured sodium floors, added taurine or B vitamins, human-grade facilities, and small-batch production. You’re paying for engineering, not branding. For a dog with an active murmur under veterinary management, that precision earns its keep; for a healthy young dog, a straightforward single-protein treat does the job at lower cost.
Frequently Asked Questions
Can dogs with heart murmurs have regular dog treats?
Often yes, but only within the sodium and protein limits your veterinarian sets. Checking the guaranteed analysis on every bag prevents accidental overload.
Are low protein treats also appropriate for heart conditions?
Frequently, because cardiac and renal diets share restrictions, though the two aren’t identical. Your vet should confirm which nutrient ceilings apply to your dog specifically.
How many treats can a dog with a murmur have daily?
Treats generally belong under ten percent of daily calories, and cardiac patients often warrant less. Follow your vet’s guidance and count treats toward the daily total.
Do supplements like taurine help dogs with heart murmurs?
Taurine supports heart muscle function and appears in several cardiac formulas, but it isn’t a treatment for structural murmurs. Discuss supplementation with your veterinarian before adding anything.
Are soft treats better for senior dogs with heart issues?
Soft textures help seniors with dental wear accept treats consistently, which matters when daily medication or supplements ride along. Nutritionally, the sodium content matters more than the texture.
Closing Thoughts
Managing a heart murmur comes down to consistency, and treats are part of that equation whether we like it or not. Start with the pick closest to your dog’s diagnosis, confirm it with your vet, and keep portions honest. A small, well-chosen reward keeps training and pill time pleasant without working against the treatment plan, and that balance is entirely achievable with any option on this list.
