Real dogs. Real relief. Hear from the people who tried everything else first.
Her stomach was always an angry red mess - bumpy, raw, and she'd lick it constantly. We'd tried medicated wipes, diet changes, everything. Started Pupied not expecting much, but within a few weeks the redness started fading. Now her belly is smooth and pink again and she's stopped the licking. First time in ages her skin actually looks healthy.
The sound of her licking her paws kept us up every night - raw, red pads she wouldn't leave alone no matter what we tried. Bitter sprays, cones, vet visits, nothing lasted. A few weeks on Pupied and the licking has almost completely stopped. Her paws look normal again and the house is finally quiet at night.
He always got raw patches on his belly and inside his ears, scratching until they bled. Constant vet trips for creams and antibiotics that only lasted a week. Started Pupied a couple months back and it's night and day — his belly's cleared up and his ears aren't red anymore. No new flare-ups since.
Collagen Peptides (400mg, Types I, II & III) - The foundation of healthy skin. Collagen makes up the bulk of your dog's skin tissue and repairs a damaged barrier from within.
Glucosamine HCl (20mg) - Supports joint cushioning and lubrication, helping keep your dog moving comfortably alongside healthier skin and coat.
Hyaluronic Acid - Deeply hydrates dry, irritated skin and keeps the barrier supple - so it stays strong instead of cracking and letting allergens through.
Cold-Pressed Liquid - Every drop is pre-dispersed to help more active ingredients reach your dog's system. Up to 97% more effective than chews or powders.

Today, over 20,000 dogs feel the benefits of stronger skin barriers with Pupied Liquid Collagen - finally free from chronic scratching, hot spots, and ear infections. Because we don't mask symptoms. We rebuild structure.
Find answers to common questions about our products, shipping, returns, and more.
It starts with the barrier. Your dog's skin is protected by a collagen barrier that keeps allergens out — but dogs lose 7–10% of their collagen a year. Once that barrier breaks down, allergens get in and trigger the scratching, hot spots, and ear infections. Our liquid collagen rebuilds it from within.
Apoquel and Cytopoint work by suppressing your dog's immune response to allergens. They quiet the symptoms, but they don't address what's actually causing them. Our collagen works differently — it helps rebuild the skin barrier so allergens can't get in as easily in the first place. Many owners start out using collagen alongside their dog's medication, then gradually taper it down as the barrier gets stronger.
It comes down to absorption. Chews and pills contain large collagen molecules that a dog's body can only take in at around 20–30%. Our liquid collagen is hydrolyzed — already broken down into tiny peptides that absorb at up to 98%. That means your dog actually gets the collagen, instead of most of it passing straight through.
Most owners notice less scratching within 2–3 weeks. More significant skin improvement usually shows up between weeks 4 and 8, and full barrier rebuilding takes around 8–12 weeks — which is why most customers choose a multi-bottle package to see it through.
Yes. These are natural building blocks your dog's body already uses every day. There's no immune suppression and no drug interactions to worry about. It's sourced from wild-caught fish and made in a FDA certified facility, so it's gentle enough for long-term daily use.
Yes. Many owners start collagen while their dog is still on Apoquel or Cytopoint. As the skin barrier strengthens and symptoms improve, they work with their vet to potentially reduce medication over time. Collagen is a nutritional supplement, so it isn't known to interfere with other treatments — but if your dog is on prescription medication, we always recommend checking with your vet first.
1–3ml per day, based on your dog's weight. One full dropper is 1ml.
Easy to adjust up or down for small or large dogs.

Skin-barrier repair isn't a focus in general veterinary practice — vets are typically trained to prescribe medications that manage symptoms. The research on collagen and skin barrier function is out there; it just hasn't gone mainstream yet. That's starting to change.
No. Chicken is one of the most common allergens in dogs, so putting it in an allergy-support product wouldn't make sense. We use bovine collagen instead — it's hypoallergenic, highly absorbable, and contains all three collagen types your dog's skin barrier relies on.
