🐶 A bit about Butternut

At Butternut, the mission is to deliver health and happiness to dogs and their humans all over the world. In order to do just that, we need a team of forward-thinking, driven people who love dogs as much as we do. And we need some pretty impressive kitchens to make it happen.

While Rudie's Kitchen and Ace's Pantry in Doncaster remain the heart of our UK operations, we’ve recently taken a massive leap forward with Sam’s Kitchen in Poland, going live in January this year. This expansion is a huge part of our story, allowing us to bring our gently cooked, human-quality meals to even more four-legged friends across Europe.

We believe dogs deserve better, and we wouldn't serve food to them that we wouldn't be happy to eat ourselves. Butternut has come a long way since Kev & Dave (our co-founders) hand-delivered the first Butternut Box, and with our new international footprint, we are looking for brilliant people to join us for this next chapter.
