"Cooper is 8 and started slowing down on walks about a year ago. I thought it was just age. Six weeks on this and he's pulling the leash again like he's three years old. His spine and hips were the issue according to our vet. I wish I'd started this sooner."

"Max is a 12-year-old Lab. He was barely walking, eyes getting cloudy, sleeping 18 hours a day. We thought we were losing him. Started taurine and by week 8 his eyes looked clearer. Week 12 he was running again. He's 13 now and our vet says his heart function improved. We got him back."

"My wife put me onto this and I'll be honest I thought it was another wellness thing. Then I actually read about it and yeah, okay, she was right. Diesel's been on it two months. No idea what's happening inside his heart but he's been an absolute menace lately in the best way possible. More energy than ever. Vet said he looks great."

"My cat Mila has had spinal stiffness since she was diagnosed with early arthritis last year. The vet said to manage it but didn't give me much to work with. Started the liquid collagen six weeks ago. She's jumping onto the couch again. First time in months."

"My girlfriend sent me an article about Boxers and heart disease and I spent about an hour going down the rabbit hole. Found out taurine isn't required in commercial dog food and that large breeds burn through it faster. Max is two years old and completely fine. I wasn't waiting. He gets it every morning, inhales his food, done. Easy decision."

"I'm a nurse so I research everything to death before buying. Read every study I could find on taurine and DCM. The 500mg dose in HappyWags is exactly what the clinical research used. Most brands either don't tell you the dose or bury it in a blend. This is the only one I trusted. Max has been on it for six months and his vet commented at his last checkup that his heart sounds perfect."
