What's Behind the Name

Most pet wellness brands compete on milligram count alone. Right:Ratio is calibrated with the right combination of molecules and ingredients, in exactly the right amounts, and in the right ratios — for the exact support your pet needs, alongside specific dosing and titration guidance.

Right ingredients. Right amounts. Right ratios.

Beyond the Formulary

Every pet, individually.

Did your vet refer you? Does your pet have a complex medical history or unique needs? Our Custom program builds a formula specific to your pet — start with the intake form (first-time customers) or the reorder form.

3. We stay with you

Right:Ratio becomes a partner in care, providing dosing guidance, adjustments, and check-ins on your pet's progress.

Birdie, 2Right:Ratio Ax:1

"Birdie's Ax:1 is definitely helping her feel more at ease. Our sweet girl is more comfortable during car rides, and we are making great progress with grooming!"

Jasper, 17Right:Ratio F:1

"After about a week he seemed to be eating more, and has become more cuddly and affectionate again — he now curls up next to me every morning, just as he did when he was a kitten. Last week he even played with some toys, which I haven't seen him do in years."
