PS: We only sell through this official site — if you see it on Amazon or eBay, it's not us.
We offer a full 60-Day Money-Back Guarantee. If you don't see real improvement in your dog's skin, coat and comfort within 60 days, simply email us and we'll sort out your refund. We're confident because this addresses the root cause (a broken skin barrier), not just symptoms. But if it doesn't work for your dog, you don't pay.
Your dog's skin has a protective barrier made of collagen, and it's breaking down faster than you think.
Dogs lose 7 to 10% of their collagen every year after age 2. Genetics, chronic scratching, antibiotics, and poor diet can accelerate it even faster. That's why some 2 or 3 year old dogs already have chronic skin issues.
As collagen depletes, gaps form. Allergens penetrate deep. The immune system goes into overdrive. That's the constant itching, hot spots, and scratching that never stops.
Apoquel and Cytopoint suppress symptoms, but they don't rebuild the barrier. That's why they fade.
Our formula rebuilds the barrier itself. All three collagen types (Types I, II & III) in liquid form for up to 98% absorption. Plus Omega 3 for fast itch relief and Vitamin C to help your dog's body turn that collagen into new, healthy skin tissue.
You're not masking symptoms. You're fixing the structure.
Mix into food once daily. Tasteless, so dogs don't notice it.
Dosage by weight:
→ Under 25 lbs: 1 mL daily, one bottle lasts about 2 months
→ 25 to 75 lbs: 2 mL daily, one bottle lasts about 1 month
→ Over 75 lbs: 3 mL daily, one bottle lasts about 3 weeks
Your dog's barrier needs ongoing collagen to stay strong. If you stop, symptoms can return.

Most owners see the first change at 2 to 3 weeks: less night scratching, calmer skin, quieter paws. The first week or two can look like nothing is happening. That's normal; the barrier rebuilds from the inside before you see it on the outside.
Deeper problems like chronic hot spots, recurring ear infections or severe allergies usually take 6 to 8 weeks.
Itching, hot spots, ear infections, paw licking: all symptoms of the same broken barrier. As it rebuilds, they improve together.
Nothing at three weeks? Check the dose against the weight table and keep going to week six. No change at 60 days, and the guarantee means you don't pay.

Is this right for my dog?
For dogs with chronic allergies who scratch constantly, have hot spots, recurring ear infections, paw licking, or thinning fur.
Can I give this with Apoquel or Cytopoint?
Yes. It's natural, non-GMO, made in a GMP-certified facility and third-party tested. There's no drug in it, so nothing interferes. Most owners keep their dog's medication going for the first 4 to 6 weeks while the barrier rebuilds, then work with their vet on reducing it.
Does it contain chicken or beef?
No. Our collagen is marine, sourced from wild-caught fish, with no chicken, beef, poultry or dairy.
Will this work if food changes failed?
Food changes remove trigger proteins but don't fix the broken barrier. Collagen helps rebuild it.
My dog has a sensitive stomach. Is this safe?
Yes. Start with half dose for the first few days if concerned.
Four problems. One bottle. Hear from the people who tried everything else first.
Two years of Apoquel and she'd still wake us up at 3am clawing at her belly. Hot spots every few weeks, cone on, cone off, repeat. Tried every shampoo, every grain-free diet. Started Nuvei on a whim — within two weeks the scratching had almost completely stopped. No new hot spots since. Her skin is healing and she's sleeping through the night. So am I.
Cytopoint would work for a few weeks then we'd be straight back to the vet. The licking was constant — his paws were stained and inflamed between the toes. Three weeks on Nuvei and the licking just stopped. The staining is fading and the skin between his pads is actually healing. First time in two years.
Every two weeks it was the same cycle — brown gunk, yeast smell, pulling away when I tried to clean them. Started this collagen after two years of ear drops and vet visits. Week four I cleaned his ears and the cotton pad came back white. Three months now and not a single infection. The vet said she's never seen his ears this clean.

Today, over 50,000 dogs feel the benefits of stronger skin barriers with Nuvei Liquid Collagen, finally free from chronic scratching, hot spots, and ear infections. Because we don't mask symptoms. We rebuild structure.
Your dog's skin has a protective barrier made of collagen. As dogs age, they lose 7 to 10% of their collagen each year. When the barrier breaks down, allergens penetrate deep and trigger the immune response. Our liquid collagen provides the building blocks to rebuild that barrier from within.
They suppress the immune response but don't fix the cause. Collagen helps rebuild the skin barrier so allergens can't penetrate as deeply in the first place.
Absorption. Chews and pills absorb at 20 to 30%. Our hydrolyzed liquid collagen absorbs at up to 98%.
Most owners notice reduced scratching within 2 to 3 weeks. Significant skin improvement typically happens between weeks 4 and 8. Full barrier rebuilding takes 8 to 12 weeks.
Yes. No immune suppression and no drug in it. Sourced from wild-caught fish and made in a cGMP certified facility.
