Hydrolysed chicken liver flavour – Palatable enough for daily use and suitable for dogs with dietary sensitivities. Give 1 chew per 13.5 kg of body weight daily.

Key Features

Formerly sold as Vetri Cardio – VetriScience have renamed this product to Extra Strength Healthy Heart. The formula is unchanged.

250 mg L-carnitine and 250 mg L-taurine per chew – The two amino acids most associated with canine heart muscle function.

30 mg Coenzyme Q10 – Supports cellular energy production in heart tissue.

150 mg arginine and 100 mg hawthorn berry extract – Included to support circulation and normal blood pressure.

Ten active ingredients in total – Also magnesium 60 mg, DMG 50 mg, berberine 50 mg, folic acid 0.9 mg and potassium.

Hydrolysed chicken liver flavour – Suitable for dogs with dietary sensitivities.

60 soft chews – Dosed at 1 chew per 13.5 kg of body weight daily.

Benefits

Supports heart muscle function – Taurine and L-carnitine are central to how heart muscle produces and uses energy.

Supports healthy circulation – Arginine and hawthorn berry support blood flow and normal blood pressure.

Supports a normal heart rhythm – Taurine, magnesium and potassium all contribute to normal electrolyte balance.

Antioxidant support – CoQ10 and DMG help counter oxidative stress on heart tissue.

Easy to give daily – A palatable chew rather than a capsule, which matters for long-term use.

Suits dogs of all sizes – Dosing scales by weight from one chew upwards.

How to Use

Daily amount – Give 1 chew per 13.5 kg (30 lb) of body weight daily.

Worked examples – A 10 kg dog takes 1 chew, a 27 kg dog takes 2, and a 40 kg dog takes 3.

Split larger doses – If giving more than one chew daily, divide between morning and evening.

For use in dogs only – VetriScience make a separate multi-species heart formula for cats and dogs.

Give consistently – Designed for regular daily use rather than occasional support.

Pregnant and breeding dogs – Safe use has not been established, so check with your vet.

Always involve your vet – If your dog has a diagnosed heart condition or takes cardiac medication, speak to your veterinarian before starting. This is a supplement, not a treatment.

How It Works

The heart is muscle that never rests, so its demand for energy is unusual — and most of this formula addresses that. L-carnitine transports fatty acids into the cell’s mitochondria to be burned for fuel, which matters because heart muscle draws much of its energy from fat. Coenzyme Q10 then works inside those mitochondria to convert that fuel into usable energy, and also acts as an antioxidant in tissue that is metabolically very active. Taurine supports normal rhythm by helping regulate how calcium and potassium move across heart muscle cells, and magnesium and potassium support that same electrolyte balance. The remaining ingredients work on circulation rather than the muscle itself: arginine is the precursor to nitric oxide, which widens blood vessels, and hawthorn berry has a long history of use in supporting blood flow. Because these are nutritional cofactors rather than drugs, the effect is supportive and gradual, which is why it is formulated for daily use.

Why Choose

Ten actives, not two or three – A broader formula than most canine heart supplements.

Formulated for dogs specifically – Rather than a multi-species formula split by weight.

A chew, not a capsule – Compliance matters most on supplements given every day for years.

Suitable for sensitive dogs – The chicken liver flavour is hydrolysed, so it suits dogs with dietary sensitivities.

Works alongside veterinary care – Designed as nutritional support for dogs under a vet’s management, not as a replacement for it.

Available at Boss Pets UK – Genuine VetriScience stock with fast UK delivery.

Active and working dogs – Where circulation and energy production are under sustained demand.

Long-term daily maintenance – Formulated for consistent use rather than short courses.

FAQs

Is this the same as Vetri Cardio?

Yes. VetriScience have renamed Vetri Cardio to Extra Strength Healthy Heart. The formula is unchanged, and bags in circulation may still carry the Vetri Cardio name.

How many chews should I give?

One chew per 13.5 kg (30 lb) of body weight daily. So a 10 kg dog takes 1, a 27 kg dog takes 2, and a 40 kg dog takes 3. If giving more than one, divide between morning and evening.

How long will a bag last?

60 chews gives 60 days for a dog under 13.5 kg, 30 days at 2 a day, or 20 days at 3.

My dog has a heart murmur or heart disease — can I give this?

Speak to your veterinarian first. This is a nutritional supplement, not a treatment, and a dog with a diagnosed heart condition needs veterinary management. Your vet can advise whether it is appropriate alongside any prescribed medication.

What does taurine do for a dog’s heart?

Taurine helps regulate how calcium and potassium move across heart muscle cells, which underpins normal rhythm and contraction.

What is in it?

Per chew: L-carnitine HCl 250 mg, L-taurine 250 mg, arginine 150 mg, hawthorn berry extract 100 mg, magnesium 60 mg, DMG 50 mg, berberine HCl 50 mg, coenzyme Q10 30 mg, folic acid 0.9 mg and potassium.

Can I give it to my cat?

No. This formula is labelled for dogs only. VetriScience make a separate multi-species heart supplement for dogs and cats.

Is it suitable for pregnant or breeding dogs?

Safe use has not been established, so check with your vet.

How long before I see a difference?

These are nutritional cofactors rather than drugs, so the effect is supportive and gradual. It is formulated for consistent daily use, and changes to heart health are assessed by your vet rather than observed at home.

When should I contact my vet urgently?

Coughing, breathlessness, reluctance to exercise, fainting or a swollen abdomen can all indicate heart problems and need veterinary assessment promptly.

Where can I buy it in the UK?

VetriScience Extra Strength Healthy Heart is available from Boss Pets UK with fast delivery.
