Most options for heart failure manage the symptoms and destroy the kidneys in the process. This targets the root cause — without destroying the rest.
Does it actually work?
Does it actually work? +

Yes! And we back it with a 90-day money-back guarantee. 

Over 10,000 dog parents have reported real improvement in energy, breathing comfort, and daily quality of life. If you don't see results, you get a full refund. No questions asked.

How long until my dog sees results?
How long until my dog sees results? +

Most dogs show the first signs of improvement around weeks 2–3. 

By 90 days, the full difference is clear. The key is consistency — don't stop before you get there.

How does this work?
How does this work? +

Cardiac decline in dogs is driven by one root cause: NAD+ depletion in the heart muscle. 

Our formula uses three natural precursors to restore NAD+ levels directly in the cardiac cells, giving the heart the cellular energy it needs to keep fighting.

Is it safe for my dog?
Is it safe for my dog? +

Yes, completely safe. Every ingredient is naturally occurring. 

It's dairy-free, dye-free, GMO-free, and allergen-free. No adverse side effects have ever been reported. As always, check with your vet if your dog is on prescription medication.

Ingredients
Ingredients +

NR (Nicotinamide Riboside) — converts to NAD+ rapidly, giving depleted cardiac cells an immediate energy supply.

NMN (Nicotinamide Mononucleotide) — sustains NAD+ production over time so levels don't drop the moment the supplement wears off.

Niacinamide — the foundational precursor that supports the base conversion pathway both NR and NMN depend on.

CoQ10 — supports the mitochondria inside cardiac muscle cells that convert NAD+ into usable energy for every heartbeat.

Resveratrol — protects heart cells from the oxidative damage that accelerates during NAD+ depletion.

It's Not A Heart Problem. It's NAD+ Depletion.

Every heartbeat runs on energy. And that energy comes from a molecule called NAD+ — the fuel for cellular energy and repair inside every cardiac muscle cell.

The heart has the highest energy demand of any organ in the body. And in a dog with congestive heart failure, NAD+ levels are critically depleted — the cells are literally contracting on empty.

That's the coughing, the labored breathing, the exhaustion after a few steps, the way they look at you with tired eyes. One cellular crisis driving every symptom.

Vetmedin and Lasix are remarkable medications. They manage the fluid. They support the mechanical function. But they were never designed to restore what the heart cells are running out of. Our formula targets that cellular crisis.

Restore the energy supply, and the dog you're fighting so hard to keep gets more good days.

What Results Could Look Like In Less Than 3 Months

"A few months ago, our 12-year-old Beagle just wasn't the same dog. He tired easily, spent most of his day resting, and didn't seem interested in the things he used to love. After adding these drops to his daily routine, we've noticed a real difference in his energy and overall spirit. He's excited for walks again, follows us around the house, and even greets visitors at the door like he used to. Every extra moment we get to see that happy tail wag feels like a blessing."

After my Golden's murmur was diagnosed, I was in pieces. Spent nights down the rabbit hole reading about DCM and NAD+ deficiency. Terrified I was slowly hurting him with grain-free food. Started ForeverDog on my vet's advice. Within 3 weeks his energy was completely transformed. Back to stealing socks and demanding walks. Latest check-up showed his heart sounds notably stronger. I finally slept without the what-ifs and that crushing guilt. Worth every penny for peace of mind. Already recommended to everyone at our dog park.

I have seen a BIG difference at about the 2 week mark. The coughing at night stopped and he's actually moving around the house again. Stuff really does work.. I ordered 4 more bottles.

Going through the same thing with my chihuahua right now. He just walked to his food bowl on his own for the first time in weeks. I cried. Good job!! 👏👏👏

I wish I'd known about this when my senior dachshund was in stage C. The medications the vet prescribed did nothing but stress his kidneys. I've since researched and NAD+ is exactly what these dogs are missing when their hearts start failing.

Our girl was given 6 months. That was 11 months ago. She's still eating, still walking, still wagging her tail when I come home. I'm not saying it's a cure but she has way more good days than bad and that's everything to me.

My 15 year old chihuahua has CHF and has been on Vetmedin and Lasix for months. Since starting this she seems more comfortable and her energy is noticeably better. So far so good.

After four weeks I'm seeing real results. He's sleeping through the night with no coughing episodes. His appetite is back. This is giving him a better quality of life and that's all I wanted.

My cavalier was diagnosed with stage C CHF in January. The vet gave us 9 months. We're at month 7 and she's still chasing the cat, still begging for treats, still sleeping in my bed every night. I don't know how much time we have left but ForeverDog gave us more of it.

Buddy was on Vetmedin and Lasix and still declining. Vet kept increasing the Lasix dose and his kidneys started showing the stress. Started this alongside his meds and within a month the decline slowed noticeably. Vet was surprised at his last bloodwork. I wasn't.

I work from home now just to spend every moment with him. Started videoing everything because I thought we were running out of time. Two months on ForeverDog and I've put the camera down. He doesn't feel like he's leaving anymore.

The vet told me to get my affairs in order with my 13 year old lab. That was 5 months ago. He's not cured. But he's HERE. Eating his food, wagging at the door, asking for belly rubs. Five more months I would never have had. That's everything.

"The cardiac NAD+ research in dogs is real, and the triple-precursor approach is what sets this apart. The meds manage the mechanical failure — but the cellular energy crisis is what nobody is addressing. This formula does.

NAD+ is the molecule your dog's heart cells run on. As dogs age — and especially as heart disease progresses — NAD+ levels in the cardiac muscle become critically depleted. The heart is beating on empty.

Forever Dog NAD+ uses Triple Precursor Technology to raise NAD+ levels through three pathways simultaneously, giving depleted cardiac cells the highest probability of getting the fuel they need to keep functioning.

Most dog parents notice the first shifts around week 2 — typically more willingness to move and slightly less labored breathing. The meaningful changes develop between weeks 6 and 12. The 90-day supply is designed to take you through the full protocol.

Forever Dog NAD+ is formulated with naturally occurring molecules the body already produces.

It is dairy-free, dye-free, GMO-free, and allergen-free. As with any new supplement, we recommend checking with your vet if your dog has a pre-existing condition or is on prescription medication.

NAD+ is a naturally occurring molecule the body already produces. It works alongside your dog's current protocol — not by interacting with the medications directly, but by addressing what the medications were never designed to touch: the cellular energy crisis inside the heart muscle. As always, check with your vet before adding anything new to your dog's regimen.

Earlier intervention works better, but later-stage dogs still respond. The mechanism — restoring NAD+ to cardiac cells — works regardless of how long the depletion has been happening. You may see slower progress than an early-stage dog, but the protocol addresses the same cellular crisis at the root of the decline.

NR (Nicotinamide Riboside) — converts to NAD+ rapidly, giving depleted cardiac cells an immediate energy supply.

NMN (Nicotinamide Mononucleotide) — sustains NAD+ production over time so levels don't drop the moment the supplement wears off.

Niacinamide — the foundational precursor that supports the base conversion pathway both NR and NMN depend on.

CoQ10 — supports the mitochondria inside cardiac muscle cells that convert NAD+ into the energy needed for every single heartbeat.

Resveratrol — protects heart cells from the oxidative damage that accelerates during NAD+ depletion and heart disease progression.
