Vet-formulated
"Most of it is preventable."
I see the same dogs every week. Stiffness that started years before anyone mentioned it, teeth that needed pulling, skin that never settled. Very little of it appears overnight.
The problem is that most supplements are dosed too low to do anything, or they're in a form the dog refuses. RUMI publishes the amount of every active ingredient, and makes it in a form dogs actually take β which is the only way a daily supplement does any good at all.
