Butternut Box: Beef It Up review

Name: Butternut Box: Beef It Up
Brand: Butternut Box

91.9/100Outstanding

FreshPuppyAdult

Flavour

Gently cooked meals, portioned to the dog and delivered frozen, with ten of the eleven in our Outstanding band and Salmon to Love just behind in Excellent. What marks the range out is how the meat is written: heart and liver named inside it on most labels. The mineral panel is almost all chelates.

What Butternut Box costs

One to two pouches per day, dependent on the size of the dog. Some recipes are subject to surcharges.

Code OFFTHELEASH50 is applied for you.

Our view

Likely to suit

Dogs kept to one protein. Several recipes hold the meat share to a single named animal
Owners who want organ meat included and spelled out
Fussy eaters. Gently cooked food holds far more aroma than anything extruded at high heat
A home with some freezer room. The pouches arrive frozen and thaw in the fridge overnight
Puppies and older dogs as much as adults. Every recipe is listed for all three
Dogs that do better with some grain. Rice, pearl barley and quinoa each turn up in the range

Worth watching

Grain in three recipes, while the other eight leave it off
Chelates of protein hydrolysates on every panel. A strict elimination trial cannot treat any recipe as truly single-species
Salmon oil in the Duo of Duck and Chicken, so that one is not fish free
No calcium figure on any label. Ask Butternut before a large-breed puppy grows on it

What's in it

Human-Quality beef: beef, ox heart, ox liver60%Heart and liver named inside the meat share. Human-Quality is Butternut's phrase, not a legal category.
Carrots13%
Sweet potatoes, peas, cauliflower4% eachNamed, with a percentage each.
Split red lentils, whole red lentils4% eachSplit ones cook down and thicken; whole ones keep their shape and fibre.
Broccoli2%
Brewer's yeast, minerals
Sunflower oil0.5%The only added oil.
Ground flaxseed, dried rosemaryFlaxseed for plant omega 3.

Zinc, iron and manganese as chelates of protein hydrolysates, the form generally absorbed more readily, plus selenium in an organic yeast-grown form.

No calcium figure on the label. For a large-breed puppy, ask Butternut for it.

Named ingredients

Human-Quality Beef 60% (Beef, Ox Heart, Ox Liver), Carrots (13%), Sweet Potatoes (4%), Peas (4%), Cauliflower (4%), Split Red Lentils (4%), Whole Red Lentils (4%), Broccoli (2%), Brewer's Yeast, Minerals, Sunflower Oil (0.5%), Ground Flaxseed, Dried Rosemary.

Against the range

Meat: 60%: beef, ox heart, ox liver; 60% on nine others, 50% on the Game.
Fat, dry matter: 33.3%; Richest in the range; the Game is 13.5%.
Selenium: Organic yeast-grown form; Only Wham Bam Lamb also adds it.

The richest bowl here and the leader of the range on our scoring.

Ten recipes declare a 60% meat share and the Game 50%, every animal named to species, with no unnamed meat or fat on any label. Where two species share a bowl, each gets a minimum percentage. Carrot leads the plant side on nearly every recipe, with red lentils, split and whole, giving most of them body.

Three carry a grain: wholegrain rice in the Duo of Chicken with Salmon, pearl barley and quinoa in Pork of the Town and Tuck in Chicken. Moisture runs from 69.0% to 74.0%. In dry matter, protein spans 35.5% to 46.4% and fat 13.5% to 33.3%.
