What Is Butternut Box?

 

Butternut Box is a UK-based fresh dog food delivery service founded in 2016 that delivers freshly prepared, gently cooked meals made with human-quality ingredients straight to your door. The meals are carefully developed by their in-house canine nutritionists & provide nutritionally complete meals designed to appeal to even picky or fussy dogs, and Butternut Box is suitable for all age groups.​

​

Every meal is tailored to your dog and is delivered to your door in portioned, easy-to-serve bags ready for your dog to enjoy at mealtimes. With a range of recipes and flexible delivery, they offer a convenient delivery service that makes it easy for many dog owners to provide their dogs with highly digestible, nutritious, and tasty meals. Each meal is tailored to you dog based on:

​

  • breed

  • weight

  • age

  • activity level
     

Unlike kibble and tinned food, all of Butternut Box's meals contain high quality, human grade ingredients including fresh meat, vegetables and added vitamins. The difference with Butternut Box meals is that unlike traditional dog food, they are slowly cooked at low temperatures to maintain the nutrients and then frozen for delivery.

​​

Owners simply:

​​

  1. Complete an online questionnaire about their dog

  2. Receive a personalised feeding plan

  3. The fresh food is then delivered frozen

  4. It is easy to defrost and serve the meals at home
     

Because the meals are pre-portioned and specially tailored to your dog, Butternut Box aims to make feeding as simple as possible while still providing balanced nutrition.

How We Tested Butternut Box

 

To enable us to write our Butternut Box review, we tested the meals with Charlie, our Wheaten Terrier who regularly acts as the official We Walk Woofs taste tester.

​

During testing we focused on several key factors:

​

  • how eagerly Charlie ate the food

  • digestion and stool quality

  • portion sizes and feeding guidance

  • ingredient quality and nutritional balance

  • overall convenience for us owners
     

Charlie happily tried all of the recipes over several weeks, which allowed us to observe both initial reaction and longer-term results.

​

We also studied the ingredients list of each meal and compared them with FEDIAF nutritional guidelines, which set the standards for complete dog food in Europe and can confirm that all meals meet and often exceed the FEDIAF requirements.

Butternut Box Ingredients & Nutritional Quality

One of the reasons Butternut Box receives strong reviews from dog owners is its simple, recognisable ingredient lists.

Typical ingredients include:

  • fresh meats such as chicken, beef or lamb

  • vegetables including carrots, peas and spinach

  • brown rice or other fibre sources

  • added vitamins and minerals

Unlike many cheaper dog foods, Butternut Box recipes avoid:

  • meat derivatives

  • artificial colourings

  • unnecessary fillers

Meals are gently cooked rather than raw, which helps preserve nutrients while making the food easier for many dogs to digest.

Each recipe is designed to provide complete and balanced nutrition, meaning it can be fed as a dog’s primary diet.
