Butternut Box is a B Corp-certified UK company founded in 2016, created out of a desire to feed dogs home-style meals that helped heal a rescue dog. They craft meals with traceable, human-quality ingredients, gently cooked at 90 °C to preserve nutrients, and delivered frozen or chilled direct to your door. Each plan is personalised based on your dog’s age, weight, activity and health, making every box made just for them. Their recipes are complete, balanced and highly digestible, with each new subscription triggering a meal donated to a dog in need.

As they have grown across the UK and Europe - including the launch of a fresh cat food brand, Marro, in 2024, and a second manufacturing facility in Poland - they have stayed true to a planet-positive path. They have cut waste to landfills by up to 90%, recycle or repurpose the rest, and use innovative heat-recovery systems to reduce gas use in cooking. They have also donated nearly 83,000 meals and over £120,000 in support through local charities, doubling their charity reach from 2022 to support communities alongside growth.
