Our story

A Yorkshire family business

Winston & Porter was founded in 2016. Drawing on over 25 years in the pharmaceutical industry, we make high-strength joint supplements for dogs and horses in Northallerton, using human-grade ingredients and printing the exact amount of every one. We own dogs and horses ourselves, so we make every supplement as if it were for our own.

We were named Animal Supplements Business of the Year (North England Prestige Awards 2020/21) and Best Premium Animal Supplement Company – UK (LUX Pet Product Awards 2021).
