We're confident because this addresses the root cause (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 7-10% 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 98% absorption. Plus MSM for fast itch relief and Hyaluronic Acid to hydrate and repair damaged skin tissue.
You're not masking symptoms. You're fixing the structure.
Mix into food once daily. Tasteless — dogs don't notice it.
Dosage by weight:
Under 25 lbs: 1 mL daily — one bottle lasts about 2 months
25-75 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 dogs show improvement within 2-4 weeks — especially reduced scratching and calmer skin. Some see relief even sooner.
For deeper issues like chronic hot spots, recurring ear infections, or severe allergies, full barrier repair typically takes 5-8 weeks.
Whether it's itching, hot spots, ear infections, or paw licking — they're all symptoms of the same broken barrier. As the barrier rebuilds, they all improve together.
But it's not just the scratching that changes. Owners tell us their dog's coat comes back thicker and shinier. Energy levels pick up. They start playing again. Sleeping through the night.

Everything owners ask before their first bottle.
Your dog's skin has a protective barrier made of collagen. This barrier keeps allergens on the surface where they belong. As dogs age, they lose 7-10% of their collagen each year. When the barrier breaks down, allergens penetrate deep and trigger the immune response — that's the scratching, hot spots, and ear infections. Our liquid collagen provides the building blocks to rebuild that barrier from within.
Apoquel and Cytopoint suppress your dog's immune response to allergens. They stop the symptoms but don't fix what's causing them. Our collagen actually rebuilds the skin barrier so allergens can't penetrate as deeply in the first place. Many customers use collagen alongside their medications initially, then reduce medication over time as the barrier strengthens.
Absorption. Chews and pills contain large collagen molecules that dogs can only absorb at 20-30%. Our liquid collagen is hydrolyzed — pre-broken into tiny peptides that absorb at up to 98%. Your dog actually gets the collagen instead of passing most of it through.
Most owners notice reduced scratching within 2-3 weeks. Significant skin improvement typically happens between weeks 4-8. Full barrier rebuilding takes 8-12 weeks, which is why most customers choose multi-bottle packages.
Yes. These are natural building blocks your dog's body already uses. There's no immune suppression, no drug interactions to worry about. It's sourced from wild-caught fish and manufactured in a cGMP certified facility. Safe for long-term daily use.
Yes. Many customers start collagen while their dog is still on Apoquel or Cytopoint. As the barrier rebuilds and symptoms improve, they work with their vet to potentially reduce medications. This doesn't interfere with other treatments.
1-3ml per day based on your dog's weight. One dropper = 1ml. Instructions are on the bottle. Easy to adjust for small or large dogs.
We offer a 60-day money-back guarantee. If you don't see improvement, contact us for a full refund. No questions asked.
Barrier repair isn't taught in general veterinary practice. Vets are trained to prescribe medications that suppress symptoms. The research on collagen and skin barrier function exists — it's just not mainstream yet. That's changing.
No. Chicken is one of the most common allergens in dogs — using it in an allergy product would risk making symptoms worse. We use marine collagen instead. It's hypoallergenic, absorbs at up to 98%, and contains all 3 collagen types the skin barrier is made from.
