Cost & Portions
How much to feed, and what it really costs.
Dog Food Calculator — How Many Grams a Day?
Enter your dog's weight, life stage and food type to get an instant estimate of its daily calorie need and how many grams of kibble, wet or fresh food that is — the interactive version of our portion-guide tables.
Open Calculator →How Much Should I Feed My Puppy?
Estimate your puppy's growing calorie need with the RER × growth-factor maths, convert it to grams, and see why the daily amount barely changes after three months — with a growth-curve feeding table.
Read Guide →How Much Should I Feed My Senior Dog?
The portion question, answered with maths: estimate your old dog's calorie need, then convert it to grams of kibble, wet or fresh — with a per-weight feeding table and a body-condition check.
Read Guide →How to Add a Topper Without Overfeeding
A fresh or wet topper adds moisture and appeal to a kibble bowl — but it's extra calories. The simple displace-don't-add maths, the 10% rule, and how to do it safely.
Read Guide →Fresh vs Kibble Cost for Large & Giant Dogs
Fresh food is priced by your dog's weight — so it gets dramatically pricier the bigger your dog. We run the real UK monthly and annual numbers and show the hybrid big-dog owners actually use.
Read Guide →Senior Dog Food: Cost vs Value
Older dogs eat less, so the maths that makes fresh food expensive for big dogs runs the other way. Why premium and fresh feeding get better value with age — and why a topper is the smartest senior spend.
Read Guide →Health & Science
The nutrition science behind the bowl — and when food is (and isn't) the cause.
Is My Dog's Food Causing This? Itching, Loose Stools, Gas, Dull Coat & Weight
Itchy skin, soft stools, smelly wind, a dull coat or creeping weight gain can all trace back to the bowl — but not always. A symptom-by-symptom router that tells a food problem from a vet problem, and shows exactly what to change if it really is the food.
Read Guide →Food for Canine Cognitive Decline — the "Dog Dementia" Diet
When an old dog's mind slows — disorientation, night-time pacing, forgotten house-training — nutrition is one of the few levers with real evidence behind it. What MCT oil, DHA and antioxidants actually do for the ageing brain, what the science shows, and how to feed a dog with cognitive decline.
Read Guide →Is Grain-Free Dog Food Actually Good?
We dig into the science, the FDA investigation, and the real-world evidence to answer whether grain-free is worth it for your dog.
Read Guide →Taurine and L-Carnitine for Dogs
A plain-English science explainer: what these two heart nutrients do, whether your dog makes its own, which foods supply them, and when supplementing actually makes sense.
Read Guide →Choosing & Switching
Picking the right food type and protein — and changing over without an upset stomach.
Wet vs Dry Dog Food — Which Is Actually Better?
Neither wins outright. The real trade-offs — cost, hydration, fussy eaters, and the "dry food cleans teeth" myth — plus why most UK owners quietly end up feeding both.
Read Guide →Best Fish & Salmon Dog Food — When Fish Is the Right Protein
Salmon and oily fish bring omega-3 no land meat can match, and are a true novel protein for chicken-sensitive dogs. When to choose fish, how to spot the label trap (4% salmon can still say "salmon"), and where the best UK fish recipes really live.
Read Guide →How to Switch Your Dog's Food Without an Upset Stomach
Changing food too fast is the top cause of diarrhoea and a refused bowl. The simple 7-day transition schedule, when to go slower, what to do if the stools go loose, and the red flags that mean call the vet.
Read Guide →How to Switch Your Dog's Food Flavour
Swapping chicken for salmon in the same range is easier than a full brand change — often just 3–4 days. When you can go fast, when to still take the week, and why a protein swap isn't an allergy test.

Browse Breeds →Best Food for Doodle Crossbreeds — Cavapoo, Cockapoo & Labradoodle
Doodles top the UK crossbreed charts, but you can't feed a label you can't predict. Why the smart move is to start simple and watch — feeding by adult size, the near-universal curly coat, and the Spaniel- or Retriever-side sensitivity lottery.
