What Is Butternut Box?
Butternut Box is a UK-based fresh dog food subscription company, founded in 2016. They cook meals using human-grade ingredients (real chicken, beef, turkey, salmon, vegetables) and deliver them frozen to your door in personalised portion packs. You get a plan based on your dog's weight, age, breed, activity level, and health conditions.
They're one of the UK's most prominent fresh dog food brands alongside Different Dog and Pure Pet Food. Butternut Box specifically occupies the premium-quality, mid-to-high price tier.

Unlike most dry foods, Butternut Box pouches list real, recognisable ingredients — not "meat meal" or "derivatives." We tested three recipes across our panel:
Chicken, Sweet Potato & Blueberry
Beef & Butternut Squash
