A dog's body makes less and less collagen every year they age — the very thing that keeps their skin strong and their itch in check. Less collagen means a weaker skin barrier. And a weaker barrier means more scratching.
Here's why thousands of owners are pouring it back in.
Sprays and shampoos wash off. This works from within. We built it to support the skin barrier itself — the thin layer that keeps the good stuff in and the irritants out. When that barrier is strong, there's less to scratch about (and less shedding, too!)
Help my dog stop itching →Formulated with Types I and III collagen, we prioritize the ingredients that make the greatest impact on your dog — not a pile of unnecessary additives. Ours is grass-fed bovine collagen. No chicken. No mystery meats. Just the good stuff their coat and skin were built to use.
Try grass-fed collagen →Itchy skin is rarely the only thing wearing your dog down. That's why we add MSM, a natural anti-inflammatory superstar that helps support not only healthy skin but also comfortable, easy movement. So the same pour that supports their coat helps support those hard-working joints, too.
Support skin & joints →Collagen can't do its job alone. Vitamin C is what helps the body actually put collagen to work. It also supports a healthy immune response — a nice bonus for a body that's busy calming things down. Think of it as the teammate that makes everything else hit harder.
Restore my dog's collagenCalming down the itch is the goal. The coat shining? That's the bragging point. Biotin supports strong skin and a shiny, full coat from the root up.
It's usually the first thing owners brag about: "the fur got softer, fuller, and got its shine back." Not to mention tougher nails, too.
Get the coat that turns heads →Best results after 90 days of consistent use
No pills to hide. No fight. No spitting it back at you. Because it's a liquid, it's highly absorbable — your dog's body can actually put it to work, not pass it through. Just pour the bacon-flavored drops right over their food with the easy dropper. Most dogs lick the bowl clean and look up for more.

"This has helped so much with my dog's itchiness, scratching and dandruff. The beef collagen kept my German Shepherd from constantly itching and getting allergy shots. His coat is vibrant and shiny, the itching stopped, and he has more energy."
"My Lab has severe food allergies and constant paw licking. Two weeks on Liquid Collagen and the difference is incredible. No more licking, softer coat, better mobility, and he's acting like a puppy again. This product is fantastic!"
"It's not quite been two weeks and my golden is scratching and licking her paws a lot less. The backs of her paws had gotten red, raw and hairless from constant licking — they're pink and healthy again and the fur is growing back! And they love the taste."
"We have four dogs, all different sizes, ages and needs. Since adding the collagen, our senior Dachshund's coat has improved and our GSD has been far less itchy. Highly recommend it!"
Fuel more memories. A few drops a day.
