Like a patch over the irritated gut lining, it seals the tiny gaps where the trouble starts
The scratching, the paw licking, the gulping and the signs of heartburn all trace back to one place: a gut lining that has lost its seal. Collagen gives his body the building blocks (glycine and glutamine) to repair and seal it, so the irritation calms from the inside, on his skin and in his stomach at the same time.

Used and recommended by veterinarians
"It's the first thing I recommend when a dog starts eating grass, scratching, or licking their paws. Most owners think that's just normal dog behavior. It's not. These are early signs your dog's body is trying to tell you something, and the longer you wait, the harder it gets to turn around."
The natural ingredients that do the work, and why
Three real actives, dosed at meaningful levels, no fillers. Each one has a clear job.
These three collagens are the building blocks his gut lining, skin barrier and coat are made of. After age 3 his body makes less every year, so a daily dose puts them back and helps calm the itch at its source.
Glucosamine helps build the protective mucus layer of the gut and the connective tissue in his skin, strengthening the barrier that keeps the irritation from starting in the first place.
Draws in and holds moisture so his skin stays hydrated and supple, and far less prone to that dry, red, itchy flare that keeps him scratching.

"The scratch-scratch-scratch at night was driving us both insane. About a week in, it dropped off. We're both sleeping now, and his paws aren't raw anymore."
"Years of him licking his front paws red and angry. I tried sprays, wipes, switching food. This is the first thing that calmed it from the inside. Wish I'd found it sooner."
