Years vs Butternut Box — Shelf-Stable vs Frozen Fresh Dog Food
If you've decided to move your dog onto fresh food, two UK brands sit at the top of almost every shortlist: Years and Butternut Box. Both are genuine fresh food — whole, named ingredients, gently cooked, portioned to your dog — and both score far above supermarket kibble on independent ratings. But they solve the "fresh food problem" in completely different ways, and that difference decides which one is right for your home.
The short version: Butternut Box is the established, premium, frozen fresh food — superb quality, but it needs freezer space. Years is the newer, shelf-stable fresh food that lives in your cupboard — solving the single biggest practical drawback of fresh feeding. This guide compares them head-to-head on storage, cost, ingredients, ratings and palatability, informed by feeding our own dog — Milo, a 12-year-old Labrador/Lurcher rescue who's wheat-sensitive — alongside published data and independent All About Dog Food (AADF) ratings.

Storage: The Deciding Factor for Most Homes
This is the difference that matters most in practice. Butternut Box is freshly cooked and then frozen for delivery. The meals arrive frozen and need dedicated freezer space, with each pouch defrosted before serving. The food is excellent — but if your freezer is already full of human food, a month's supply of dog meals is a genuine logistical problem, and one of the most common reasons owners give up on frozen fresh food.
Years sidesteps this entirely. Its steam-vessel cooking process makes the food shelf-stable, so it stores in the cupboard until opened (then refrigerated once open, like any fresh food). For flats, small kitchens, or households that already battle for freezer space, this is the single biggest reason people choose Years over Butternut Box. No defrosting, no freezer Tetris, no planning ahead.
Verdict: Years, comfortably — unless you have freezer space to spare and don't mind defrosting.
Ingredients & Quality
Both brands are built on the same fresh-food principles: whole, named meat and vegetables, gentle cooking that preserves nutrients far better than the high-heat extrusion used for kibble, and no cheap fillers or "derivatives". This is why both sit near the top of independent ratings.
Years holds the highest-ever AADF rating for a whole-food meal at 96%, and crucially every recipe is grain- and legume-free — no wheat, no peas or lentils bulking out the protein. Its recipes were developed by a specialist in veterinary clinical nutrition alongside an ex-luxury-yacht head chef, an unusual but effective pairing.
Butternut Box also rates very highly on AADF and uses high-quality named ingredients. Its edge is customisation: recipes can be tailored around specific allergies and sensitivities (wheat-free options are available), and the portions are calculated precisely for your dog's weight and goals. If your dog has a very specific profile, Butternut Box's tailoring is a real advantage.
Verdict: Years for guaranteed grain-/legume-free and the top independent rating; Butternut Box for recipe customisation around individual sensitivities.
Cost
Both are premium products — you're paying for fresh food, not supermarket kibble. Butternut Box publishes a range of roughly £1.60/day for a small dog up to around £6/day for a large one. That scaling matters: frozen fresh food gets expensive fast for big dogs, both in price and in freezer volume.
Years uses fully personalised pricing, so there's no single headline figure — you need to run its plan calculator with your dog's exact weight. The trial starts from around £7. For larger dogs in particular, the combination of shelf-stable storage and personalised plans can make Years the more practical long-term choice, though you should compare the exact per-day figures for your own dog before deciding.
Verdict: Too close to call on price alone — run both calculators for your dog. The cost gap widens against Butternut Box for large dogs.
Palatability & Suitability for Seniors
Both foods are highly palatable — gentle cooking and real ingredients are exactly what tempt a fussy or fading appetite. Butternut Box's high moisture and soft texture make it a standout for dogs who've gone off their dry food entirely; it's often the food owners turn to when nothing else works.
Years is also excellent for seniors: the gentle cooking aids digestion, the strong aroma helps fading appetites, and the grain-/legume-free recipes suit sensitive older dogs. This is the route we take with Milo (12), who's wheat-sensitive — shelf-stable, grain-free fresh food fits his needs without the freezer hassle. For a fuller breakdown of feeding older dogs, see our best senior dog food guide.
Verdict: Butternut Box for the fussiest eaters; Years for sensitive or grain-intolerant seniors.
Which Should You Choose?
There's no universal winner — it comes down to your dog and your kitchen:
- Choose Years if: you have no freezer space, want guaranteed grain- and legume-free recipes, or have a sensitive or senior dog. It's our overall top fresh-food pick.
- Choose Butternut Box if: you have freezer room and want the highest-moisture, most customisable frozen-fresh meal — especially for a fussy dog who's turned its nose up at everything else.
- Have a large dog? Weigh the cost and freezer volume carefully. Frozen fresh food scales up expensively; shelf-stable Years can be the more practical option.
- Still unsure? Both run low-cost trials with cancel-anytime terms. Trial each over a 7-10 day transition and let your dog decide.
For the wider field — including air-dried and tailored options that cost less — see our full best fresh dog food UK guide, where Years is our top pick and Butternut Box ranks among the best premium choices.
How to Switch
Whichever you choose, transition gradually over 7-10 days, mixing increasing amounts of the new fresh food into the old. Fresh food is richer and more digestible than kibble, so a sudden switch can cause loose stools — slow down if you see any upset. Both brands' trial boxes are sized to cover the changeover and include feeding guidance for your dog's weight. As always, if your dog's appetite, weight or toileting changes noticeably and doesn't settle, book a vet check.
Frequently Asked Questions
What's the main difference between Years and Butternut Box?
Storage. Years is gently steam-cooked and shelf-stable, so it lives in your cupboard until opened — no freezer needed. Butternut Box is freshly cooked then frozen, so it needs dedicated freezer space and a bit of planning to defrost. Both are genuine fresh food made from whole, named ingredients; the practical question for most owners is whether they have the freezer room for Butternut Box, and that's where Years has the edge.
Is Years or Butternut Box cheaper?
It depends on your dog's size and the exact plan. Butternut Box publishes a range of roughly £1.60/day for a small dog up to about £6/day for a large one. Years uses fully personalised pricing, so you need to run its plan calculator with your dog's weight for an accurate figure — its trial starts from around £7. As a rule, both sit at the premium end of the market; the cost gap matters most for large dogs, where frozen fresh food like Butternut Box gets expensive fast.
Which is better for a senior dog?
Both suit seniors well — the gentle cooking, higher digestibility and stronger aroma tempt fading appetites and are kind to ageing digestion. Years has a slight edge for many senior households: it's grain- and legume-free across the whole range (useful for sensitive older dogs), holds the highest-ever AADF rating (96%), and the cupboard storage removes the freezer-space hurdle. Butternut Box's high moisture and customisable recipes are excellent if your senior is fussy or has gone off dry food. Our own 12-year-old Lurcher, Milo, does best on grain-free gently-cooked food.
Do I need a freezer for Years or Butternut Box?
Only for Butternut Box, which is delivered frozen and stored in the freezer until you defrost each pouch. Years is shelf-stable and stored in the cupboard until opened, then refrigerated once open like any fresh food.

Which has better ingredients and ratings?
Both use whole, named ingredients and gentle cooking, and both rate far above mainstream kibble. Years holds the highest-ever All About Dog Food (AADF) rating for a whole-food meal at 96%, and every recipe is grain- and legume-free.

Trial boxes are sized to cover the 7-10 day transition period, which is the sensible way to see how your dog responds before committing to a full plan.
