Your pet is more than a pet.

Inside every wag, trillions of cells are talking to each other. Peptides — short chains of amino acids — carry many of those messages: a signal to renew cartilage, to calm the gut lining, to keep a steady rhythm through the night.

We choose well-studied sequences, dose them by weight, and bake them into a chew they’ll actually ask for — so the support shows up every single day.

Over 12,480 tails, wagging (and counting).
