Pure Ingredients For your pet
Hydrolyzed Bovine Collagen
Collagen holds your dog's skin together. Type I strengthens skin elasticity and firmness, reducing wrinkles and sagging. "Hydrolysed" means it's broken down small enough for your dog's body to actually absorb and use. Your dog's skin finally gets what it needs to regenerate.
Fish Collagen
This marine collagen provides Type I and Type II in a form your dog's body recognizes and absorbs instantly. Research shows fish collagen reaches skin tissue quickly, supporting both skin health and joint mobility. Two critical benefits in one powerful ingredient.
Egg Membrane Powder
This ingredient contains natural hyaluronic acid—the molecule that holds 1,000 times its weight in water. It floods your dog's skin with deep hydration while supporting cartilage health simultaneously. Your dog's skin stays plump, elastic, and youthful from the inside out.
Vitamin E
Dog food is cooked at extremely high temperatures, which destroys vitamin E—an antioxidant your dog's cells need to fight free radical damage. Without it, skin cells break down prematurely and inflammation takes hold. Vitamin E gives back what food processing takes away.
Vitamin C
Here's what other supplements won't tell you: collagen without vitamin C is like a construction site without workers. Vitamin C converts procollagen into stable, usable collagen and protects existing collagen from breaking down. Together, they're scientifically proven to be more effective than collagen alone.
Biotin
Your dog's body needs biotin to produce keratin—the protein that makes coats shine and skin stay strong. Without adequate biotin, their coat becomes dull and brittle while skin loses its regenerative power. Biotin restores what modern dog food destroys.
Cellulose Powder
Unhealthy gut equals unhealthy skin. Period. This prebiotic feeds beneficial bacteria, strengthening immunity and improving digestion, which leads to healthier, more vibrant skin and coat. 70% of your dog's immune system lives in their gut.
Veterinary-backed collagen support for youthful vitality.
Every week, I watched perfectly healthy dogs develop skin issues, lose their coat shine, and slow down before their time. Their owners had done everything right—premium food, regular grooming, quality care. Yet their dogs were aging rapidly. After 20 years in practice, I finally understood why: modern dog foods are missing the specific nutrients skin needs to maintain itself. Pawse Aging Collagen provides what's missing.
