FullPup is a free homemade dog food calculator built for owners who want to know exactly what is going into their dog's bowl. It takes your dog's breed, weight, life stage and activity level and works out a balanced meal using proper nutritional guidelines.
There are no subscriptions and no sign-up forms. It works on your phone, tablet or computer, so you can pull it up in the kitchen, print off the recipe, and get cooking. Just real food, weighed out properly.
How it works
This isn't about following a random recipe found on a blog. FullPup is built using the FEDIAF nutritional guidelines, the industry standard here in the UK.
-
Metabolic Maths We use the proper metabolic weight equation to set calorie targets. It ensures your dog gets exactly what they need based on their actual size, energy levels, life stage, breed, and whether they're neutered.
-
Safety Limits Some ingredients are great in small doses but no good in large ones. The tool has built-in caps for things like liver and certain veg to keep the bowl safe, set per ingredient based on each food's actual risk, not a blanket category rule.
-
Live Tracking As you add ingredients, the tool tracks calories, protein and fat against UK targets in real time. If the balance is off, it tells you straight away.
A bit of common sense
This tool is a guide based on standard nutritional requirements for healthy dogs. It does not replace the advice of a professional. If your dog has specific health conditions or medical needs, always have a word with your vet before you make big changes to what they eat.
We're also transparent about what the tool can't do. Calcium is the hardest gap to close through food alone. Muscle meat is high in phosphorus and almost zero in calcium, so the more meat-based the meal, the worse the Ca:P imbalance becomes. FEDIAF guidelines require a minimum ratio of 1:1; unsupplemented homemade diets typically run closer to 1:10. Eggshell powder or bone meal in every bowl is essential. A quality daily supplement then covers vitamin D, B12, zinc and omega-3s, nutrients that are genuinely difficult to hit consistently through whole foods.
