Science-based daily heart support: a vet listens to a Yorkie's heart, shown glowing in its chest. Made for every breed: Chihuahua, Cavalier, Great Dane, Shih Tzu, Doberman, Boxer and Maltese. The Heart Chew jar sits on the exam table and a whiteboard shows how a dog's heart moves blood around the body
A 10-year-old Cavalier beside The Heart Chew: heart muscle support, healthy heartbeat, heart energy and more good years
Four heart bottles, one daily chew: the taurine, L-carnitine, CoQ10 and fish oil bottles, all in The Heart Chew
Inside your dog's heart: every beat runs on taurine, L-carnitine, CoQ10 and omega-3 EPA + DHA
What to expect: filling the gaps one chew at a time, from day 1 to month 3 and every day after
Built for hearts that work overtime: Cavalier, Doberman, Boxer, Chihuahua, Shih Tzu, Yorkie, Dachshund and Great Dane
The science behind The Heart Chew: taurine 250 mg, L-carnitine 250 mg, CoQ10 30 mg, omega-3 EPA + DHA 150 mg and vitamin E 10 IU per chew
Why heart-dog parents switch: one chew instead of four bottles, every mg on the label, dosed by weight, and dogs think it's a treat
Heart changes start years before you hear them: a vet hears a soft murmur at a checkup. The best time to start is before the murmur; the second best time is today
Daily chew guide with real dog sizes: 1 chew under 25 lbs, 2 chews from 25 to 60 lbs, 3 chews over 60 lbs

Why start now

Every dog's heart works harder with age

Watch the average dog grow up. Heart changes creep in quietly from middle age, usually long before anything looks wrong at home.

The Heart Chew jar with heart-shaped chews

Illustration of typical age-related heart changes, not clinical data. About 1 in 10 dogs has heart disease (Merck Veterinary Manual); about 3 in 4 cases are heart valve disease (ACVIM, 2019). The Heart Chew is a daily supplement, not a treatment. Not a substitute for veterinary care.

Give their heart what it runs on

    Topped up every day

    Taurine, L-⁠carnitine and CoQ10: the fuel heart muscle burns every beat.

  3. 3

    Months 2–3

    Omega-3s build up

    EPA and DHA levels build with daily use. The routine is locked in.

    Bring the jar

    Every mg is on the label, so your vet sees exactly what your dog gets.

Already on heart meds?

Keep the meds. Add the nutrition.

Vetmedin (pimobendan) helps the heart pump. It doesn't feed the heart muscle. The Heart Chew does a different job: it delivers the taurine, L-⁠carnitine, CoQ10 and omega-⁠3s heart muscle uses every single beat. Keep your vet's plan exactly as it is and add the daily chew.

One chew replaces the stack

Why owners are ditching powders and pill stacks

A taurine powder covers one of the four. The bottle stack covers all four, in four bottles, at human doses. The Heart Chew covers all four in one chew, dosed for your dog's weight.
