A quiet risk in small breeds

Some hearts need a closer eye than others

Certain small breeds, Cavalier King Charles Spaniels, Chihuahuas, Cocker Spaniels, dachshunds, Pomeranians, and Yorkshire terriers among them, are more prone to heart concerns as they age. It often starts quietly, sometimes as a murmur your vet hears before you notice anything at all.

The years before symptoms appear are exactly when a heart-supportive daily routine matters most. If your vet has already flagged something, keep them in the loop; this is a daily supplement, not a substitute for their care.

Ingredients come first

Every nutrient earns its place

Each ingredient is here for one reason: to support the canine heart through the things it relies on every day, a balanced inflammatory response, steady rhythm, cellular energy, and antioxidant defense. Each is included in a bioavailable form, unlike single-ingredient heart supplements that cover only one piece.

The thinking behind it

Why Heart & Cardio is built the way it is

Built on canine cardiac nutrition

Nutrients with a real research base

The blend is built around nutrients that are well documented in veterinary nutrition for their roles in normal heart function, taurine, CoQ10, L-carnitine, and omega-3s. Add your real citations and study summary here.

A blend, not a single nutrient

Several nutrients, each with a job

The heart draws on many things at once: energy, a balanced inflammatory response, steady rhythm, and antioxidant defense. Single-ingredient supplements cover one piece. This blend brings several together, each in a bioavailable form.

Formulated without hawthorn

Made to fit around your vet's plan

We left hawthorn out and added no sodium, keeping the formula focused and easy to fit into a daily routine. If your dog takes any heart medication, share the ingredient list with your veterinarian before starting so the two of you can decide together.

Thoughtful by design

What is not in the tub matters too

A clean formula is as much about what you leave out as what you put in. Heart & Cardio Powder is built to sit easily inside a daily routine.

No added sodium. Salt is the last thing a sensitive heart needs, so there is none added here.

Formulated without hawthorn. We left hawthorn out by design and kept the blend focused on well-documented cardiac nutrients.

Made to work with your vet, not around them. If your dog takes any heart medication, share the ingredient list with your veterinarian before starting, so the two of you can make the call together.

A 30-second daily ritual

Scoop. Sprinkle. Done.

Scoop the powder

Use the scoop in the tub. The right daily amount depends on your dog's weight.

Sprinkle on their food

Mix it into wet food or sprinkle over kibble. Most dogs love the natural seafood taste.

Repeat every day

Consistency is what matters. Daily support builds over weeks, not overnight.

Daily amount: 1 scoop under 35 lbs, 2 scoops from 35 to 70 lbs, 3 scoops over 70 lbs. Full guide on the label.

Scoop, sprinkle, done

So easy even your dog will remind you

Photo: hand holding a scoop of powder over the tub

Powder, every morning

Sprinkle one scoop over your dog's food every morning. One scoop for dogs under 35 lbs, two for larger breeds. Most dogs do not even notice it is there, so mix it into wet food or over kibble and let them eat as normal.

Consistency, daily use

Give it every day. Nutritional support builds gradually over several weeks of consistent use. Try not to skip days, and let your vet track how your dog is doing over time.

One simple routine

One scoop covers the blend: taurine, omega-3s, CoQ10 ubiquinol, L-carnitine, magnesium, and more, each in a bioavailable form. No need to stack several products or juggle multiple tubs.

The nutrients in this blend, taurine, CoQ10, L-carnitine, and omega-3s, are well documented in veterinary nutrition for their roles in normal heart function.

Nutrient

Taurine in canine heart nutrition

Taurine is a well studied amino acid tied to the normal function of the heart muscle in dogs.

Nutrient

CoQ10 and cellular energy

CoQ10 is documented for its role in the energy production of hard-working cells, including those of the heart.

Nutrient

L-Carnitine and fatty-acid energy

L-carnitine helps cells convert fatty acids into usable energy, a role studied in cardiac nutrition.

Nutrient

Omega-3s and cardiovascular wellness

EPA and DHA omega-3s are widely researched for supporting a normal inflammatory response and overall wellness.

Verified peer-reviewed citations for each nutrient will be linked here before launch. This information is about the individual nutrients, not about our specific product. This product supports normal heart health; it is not a treatment for heart disease. Always work with your veterinarian for a dog with a diagnosed heart condition.

Heart & Cardio Powder FAQ

What is in the powder?

A blend of nutrients chosen for the canine heart: taurine, CoQ10 as ubiquinol, L-carnitine, magnesium glycinate, EPA and DHA omega-3s, New Zealand Green-Lipped Mussel, and vitamin E. No added sodium, no hawthorn, no fillers.

Can this treat or prevent heart disease?

No. This is a daily nutritional supplement that supports normal heart health, not a medicine and not a treatment for any heart condition. Be wary of any product that claims otherwise. If your dog has a diagnosed heart condition or a murmur, your veterinarian leads the care, and this powder can only be part of the picture with their guidance.

My dog is already on heart medication. Can I give this too?

Talk to your veterinarian first. Bring them the full ingredient list so they can check it against your dog's medication and condition. We deliberately left out hawthorn and added sodium, but your vet knows your dog and should make the call.

Which dogs is this made for?

We formulated it with the small breeds most prone to heart concerns in mind, such as Cavaliers, Chihuahuas, Cocker Spaniels, dachshunds, Pomeranians, and Yorkshire terriers, whether as daily support for an older dog or a routine for a younger one at breed risk.

How long until I notice anything?

Nutritional support builds gradually. Most owners give it several weeks of daily use, and our guarantee runs a full 90 days. Any changes in your dog's heart health should always be assessed by your vet, not by the supplement.

Will my dog actually eat it?

Most dogs take to it mixed into wet food or over kibble with a splash of water. If yours turns their nose up, the 90-day guarantee has you covered.

What is the 90-day guarantee?

Use the powder daily. If you are not happy after up to 90 days, email us and we will make it right. It is the same happy-dog guarantee behind every Vital Paw product.

90 days to see how they do

Give your dog one scoop a day. If you are not happy within 90 days, we will refund you. And if your dog has a heart condition, please keep your vet in the loop; this is a daily supplement, not a substitute for their care.
