Lost my first Golden at 10. Vet said it was "just aging" but watching him decline from 8-10 broke my heart. Got Bailey at 7 and immediately started HappyWags because I wasn't taking any chances this time. She's 12 now and honestly she acts younger than she did at 8. So much energy, still greets me at the door every day. My husband keeps saying she's aging backwards. I just wish I'd known about this with my first dog — those two years haunt me.

"Max is a 12-year-old Lab. He was barely walking, eyes getting cloudy, sleeping 18 hours a day. We thought we were losing him. Started L-Carnitine and by week 8 his eyes looked clearer. Week 12 he was running again. He's 13 now and our vet says his heart function improved. We got him back."
"Bruno is a Newfoundland and was diagnosed with DCM at 7. It was heartbreaking. He's doing so well now and L-Carnitine supplementation has been part of his routine since day one of his diagnosis. His last two cardiology visits have genuinely shocked his vet. He's not cured but he's happy and he's here and that's everything."
Must-Have
"My girlfriend sent me an article about Boxers and rapid aging and I spent about an hour going down the rabbit hole. Found out L-Carnitine isn't required in commercial dog food and that large breeds burn through it faster. Max is two years old and completely fine. I wasn't waiting. He gets it every morning, inhales his food, done. Easy decision."

A Struggling Heart
L-Carnitine is the most abundant amino acid in the heart muscle — without enough of it, cardiac function silently deteriorates.
Deteriorating Vision
The retina holds the highest concentration of L-Carnitine in the entire body. Low levels directly compromise your dog's eyesight.
Weakened Immunity
L-Carnitine regulates the immune response and controls inflammation — keeping your dog healthy and resilient year-round.

Rapid Aging
As one of the body's most powerful antioxidants, L-Carnitine protects cells from the oxidative damage that accelerates ageing.

Proven Benefits. Backed by Vet Science.
Offsets the natural decline that comes with every passing year.
L-Carnitine synthesis naturally declines as dogs age — and with it, the body's ability to protect cells from oxidative damage. Daily supplementation gives your dog's body what it can no longer produce on its own.
- Protects cells from the oxidative damage that drives premature aging
- Supports brain health & sustained energy through every life stage
Regulated immune response and reduced cellular inflammation.
L-Carnitine acts as a direct antioxidant inside immune cells, neutralising the free radicals that drive chronic inflammation. It keeps your dog's immune system calibrated to fight back without overreacting.
- Neutralises free radicals at the cellular level
- Supports faster recovery and year-round immune resilience
Supports healthy vision and prevents haziness.
The retina holds a higher concentration of L-Carnitine than almost any other tissue in the body. When levels fall, photoreceptor cells deteriorate — gradually, silently, and often irreversibly.
- Protects retinal cells from oxidative stress and age-related damage
- Deficiency is a leading nutritional cause of progressive vision loss in dogs
The amino acid your dog's heart depends on most.
L-Carnitine controls calcium movement inside cardiac cells — the mechanism behind every heartbeat. When levels drop, the heart muscle silently weakens and the chambers begin to dilate.
- Helps prevent the muscle thinning and chamber dilation associated with DCM
- The single most critical amino acid for long-term canine heart function
Is Cerise Paws Right for Your Dog?
See if your dog is at risk:
Senior Dog
+
L-Carnitine synthesis naturally declines with age. The older your dog gets, the less their body produces on its own — and the more their heart, eyes, and immune system depend on adequate levels. Seniors need it most.
My Dog Seems Healthy
+
That's exactly when to start. L-Carnitine deficiency is completely silent — no symptoms, no warning signs — until the heart is already under serious stress. By the time something looks wrong, the deficiency has been building for months.
At-Risk Breed
+
Golden Retrievers, Cocker Spaniels, Newfoundlands, Dobermans, Great Danes and Labrador Retrievers all have a documented predisposition to L-Carnitine -deficient heart disease.
For these breeds, supplementation isn't optional — it's responsible ownership.
Grain-Free Diet
+
This is the highest risk factor we know of. Grain-free diets are consistently linked to lower L-Carnitine levels in dogs — it's the reason the FDA launched a full investigation. If your dog is eating grain-free, they need this.
My Vet Hasn't Mentioned L-Carnitine
+
Most vets only test L-Carnitine levels after symptoms appear. By then, the deficiency has already done permanent damage.
CerisePaws is preventative — it fills the gap before your vet ever needs to have that conversation with you.

Got Questions? We've Got Answers!
Does L-Carnitine supplementation actually work?
+
L-Carnitine supplementation is a necessity for dogs on a standard diet. AAFCO sets zero L-Carnitine requirements for dog food, which means most dogs are quietly running low regardless of how good their food looks on the label. A daily 500mg dose removes the uncertainty entirely.
How is this different from the L-Carnitine already in my dog's food?
+
AAFCO sets zero minimum L-Carnitine requirements for dog food. Whatever trace amount is present is further depleted by cooking, processing, and storage. HappyWags delivers a direct, measured 500mg dose — not an estimate buried inside a formula with no transparency on what your dog is actually getting.
Is CerisePaws right for puppies?
+
L-Carnitine is safe for dogs of all ages. Puppies in high-growth phases and large-breed puppies in particular benefit from early L-Carnitine support. Follow the weight-based dosing on the label — the same guide applies regardless of age.
What if my dog is picky?
+
CerisePaws is tasteless and odourless. It disappears into food completely — no texture, no smell, no change your dog will notice. If yours is particularly picky, mix it into a small amount of wet food or broth. We have had no reported cases of a dog refusing their meal because of it.
My dog has been diagnosed with DCM/CHF. Can HappyWags help?
+
L-Carnitine supplementation is one of the first things veterinary cardiologists recommend when DCM/CHF is diet or deficiency-related.
CerisePaws delivers the exact dose they use clinically — nothing more, nothing less. Single ingredient and vet approved.
Which breeds are most at risk?
+
Large and giant breeds carry the highest risk — Dobermans, Great Danes, Newfoundlands, Irish Wolfhounds, and Boxers among them. Golden Retrievers have been subject to specific FDA scrutiny. Cocker Spaniels are consistently flagged. But any dog on a grain-free diet, regardless of breed, faces elevated risk — and any dog eating commercial kibble is getting less L-Carnitine than the label suggests.
When will I see results?
+
Most owners notice the first changes within 4–6 weeks — better energy on walks, a brighter coat, eyes that look clearer and more alert. These aren't placebo effects. L-Carnitine directly supports the retina, immune function, and cellular energy production, so the visible changes reflect real underlying shifts. For dogs with existing deficiency, deeper cardiac improvements build over 3–4 months. For preventative buyers, those surface-level changes are your signal that it's working — the cardiac protection is happening underneath, where you can't see it. We recommend committing to at least 90 days.
