Butternut Box is a B Corp-certified UK company founded in 2016. It began with a simple goal to feed one rescue dog proper, home-style meals that helped him heal.

They make fresh food using traceable, human-quality ingredients, gently cooked at 90 °C to lock in nutrients. Meals are delivered frozen or chilled direct to your door. Each plan is tailored to your dog’s age, weight, activity and health, so every box is made just for them. Recipes are complete, balanced and easy to digest. Every new subscription also triggers a meal donation to a dog in need.

Operating across the UK and Europe, they launched fresh cat food brand Marro in 2024 and opened a second manufacturing site in Poland. As they have grown, they have stayed committed to a planet-positive path cutting waste to landfill by up to 90%, recycling or repurposing the rest and using heat recovery systems to reduce gas use. They have donated nearly 83,000 meals and over £120,000 to local charities, doubling their reach since 2022.
