But even on taurine, a heart chew comes up small: about 100 to 250 mg.
One scoop of Steady has 1,000 mg of taurine. That's twice the biggest taurine dose on the shelf.
One scoop = the taurine of 4 to 10 heart chews.
Why does 1,000 mg of taurine matter? His body makes some taurine, and big dogs make less of it. On the same food, a Newfoundland made about half the taurine a Beagle did. And dog food doesn't have to contain any. So every scoop puts a full gram in his bowl, to support healthy taurine levels.†
And a squeezing heart still needs fuel.
His heart never stops. Not when he sleeps. Not when he naps on the couch.
Every beat takes energy. And his heart gets most of that energy from fat.
Here's the catch. Inside every heart cell are tiny engines called mitochondria.
Fat can't get into those engines by itself. It needs a truck to carry it in.
That truck is L-carnitine.

"I'd been giving him a taurine chew for two years. I had no idea his heart needed the fuel too." ★★★★★Dana R., Verified Purchase
Think of a gas station with full tanks and a broken pump.
The gas is right there. The cars still drive away empty.
That's a heart with plenty of fat and not enough L-carnitine.
📄 Physiological Reviews · 2010
The heart gets most of its energy from fat.
In a 1997 vet study, dogs got taurine and L-carnitine together, as a pair.
3. A Newfie Can Run Low On Taurine While Looking Perfectly Healthy
"He was the picture of health at every checkup. That's exactly what scared me." ★★★★★Lisa K., Verified Purchase
Heart muscle disease starts quiet.
No cough. No tired days. Nothing you'd see at home.
That's why Boxers get heart checks starting at age 3.
And a normal blood test can miss it.
In one long feeding study of big dogs, the taurine in their muscles fell by half. Their blood tests barely moved.
Dog food doesn't even have to contain taurine. Cat food does. Dog food doesn't.
📄 The pet food rules (AAFCO)
Cat food: taurine
REQUIRED
Dog food: taurine
NOT REQUIRED
You can't see inside his muscles. You can control what goes in his bowl.
Steady prints the dose right on the front: 1,000 mg of taurine and 1,000 mg of L-carnitine in every scoop.
⚠️ WHY NEWFIE OWNERS DON'T WAIT FOR A SIGN
Owners who lived it said it best:
"...an X-ray revealed a nightmare: her heart was five times its normal size." A Golden owner, in their own words
"We had just taken a 3 mile walk Saturday and he was so happy and healthy. All of his annual vet visits checked out OK."A Golden owner, about their almost 8 year old Golden
"Charlie was running through the yard when he suddenly collapsed... He was only 9."A Golden owner, in their own words
And when scientists looked inside the hearts of Boxers with heart muscle disease, L-carnitine kept coming up short:
📄 Journal of Nutrition · 1994
In Boxers with heart muscle disease, low L-carnitine in the heart keeps showing up.
One Boxer's heart had 38% of the normal amount. Less than half.
At NC State's vet hospital, a typical heart workup runs $600 to $1,400.
That bill, you can pay.
Losing him early is the one you can't.
👇 And here's where the Pinch Problem hits big dogs hardest. Reason #4.
4. His Heart Chew Is The Same Size As A Yorkie's. His Heart Isn't.
"My 72 lb boy was getting the same chew as my neighbour's Maltese. That never sat right with me." ★★★★★Tom H., Verified Purchase
Big dogs make less taurine than small dogs.
On the same food, Newfies had half the taurine of Beagles. That's your breed.
🐕 WHY BIG DOGS RUN LOW
They make less taurine on their own. In one study, large dogs made less than Beagles on the same food.
Dog food doesn't have to contain any. Cat food does.
A blood test can look normal while the muscle runs low. In one long feeding study, muscle taurine fell by half while the blood barely moved.
A chew is sized for one bite. His heart is sized for a 120 lb Newfie.
His heart never rests, and it runs mostly on fat. L-carnitine is the truck that carries the fat in.
Dog food doesn't even have to contain taurine, and big dogs make less of their own.
You can't see inside his muscles. You can control what goes in his bowl.
"Isn't this just marketing hype?"
Both doses are printed on the front: 1,000 mg of taurine and 1,000 mg of L-carnitine in every scoop. Every other amount is listed too. No proprietary blend.
Now flip over your chew tub and compare.
When Tufts cardiologists audited 60 heart supplements, very few reached the commonly recommended doses.
And you get 60 days from delivery. Not right for your dog? Send back the unused pouches with your order number for a full refund.
You've got three choices:
1️⃣ Keep the tub. A pinch a day, $135 to $307 a year.
2️⃣ Buy more chews. To match his Steady dose, he'd need 12 to 60 a day.
3️⃣ Order Steady by his weight at the Fall Sale price, with 60 days to decide.

His dose: 3 scoops a day. Buy 3, Get 2 keeps him covered the longest, with free shipping.

It's the truck that carries fat into the mitochondria, the tiny engines in his heart cells, where the fat turns into energy. His heart runs mostly on fat. Every scoop of Steady has 1,000 mg.
Why not just give him more chews?
A gram won't fit in a chew. To match one day of Steady for a 120 lb Newfie, he'd need 12 to 60 chews.
What form of L-carnitine is it?
The L form, the one the body uses. 1,000 mg of L-carnitine per scoop, printed on the front.
Does a powder even absorb?
Taurine absorbs fast and completely, even at gram doses. In a study in people, it peaked in the blood about 90 minutes after a dose.
Is this a subscription?
No. You pay once. Nothing else ships unless you order again.
What size dog is it for?
Any size. Scoops go by weight: ½ up to 10 lb, 1 at 11 to 25 lb, 2 at 26 to 75 lb, 3 over 75 lb.
What's in it?
Per 3 g scoop: L-carnitine 1,000 mg, taurine 1,000 mg, hydrolyzed chicken liver 570 mg, brewer's yeast 300 mg, fish powder 100 mg, silicon dioxide 30 mg.
Will he eat it?
It has chicken liver for flavour and goes right on his dinner. Start with half his daily scoops and build up.
Can I keep his food?
Yes. It goes on whatever he eats now: kibble, wet, raw or home-cooked.
Is it safe with his other supplements or medication?
If your dog takes any medication or is under a vet's care, check with your vet first. Safety in pregnant or breeding dogs has not been established.
P.S. You have 60 days to try it. Not right for your dog? Full refund. The Fall Sale price ends at midnight tonight.
P.P.S. Remember: 1,000 mg of taurine and 1,000 mg of L-carnitine in every scoop. A whole year of heart chews carries less L-carnitine than 5 weeks of Steady. Claim the Fall Sale price 👉
