The Dog Food Calculator
Two sums that most owners have never been shown. Ten seconds each.
Which food actually has more?
A bag with more water in it looks worse than it is. Take the water out of both and compare what is left.
Food A
Food B
Fill in protein and moisture for both foods and the answer appears here.
How many treats is too many?
Treats are meant to stay under a tenth of what your dog eats in a day. Here is what that tenth actually looks like.
Put in your dog's weight and the treat budget appears here.
| Treat | Calories | Fits in the day |
|---|
Approximate, check the packet. Dental chews and training treats vary a lot between brands.
This is an estimate. The feeding guide on the bag and your vet take priority, especially for puppies, seniors, or dogs with a health condition.
The rest of the bag
The calculator does two sums. The book reads the whole bag.
- The four things on the back of the bag that actually matter, and how to judge any food in about ninety seconds.
- What the product name legally means: why "Chicken Dinner" needs far less chicken than "Chicken Dog Food".
- One hundred treats and games that fit inside the daily treat budget.

I understood the individual chapters, but the three invented food bags were where it clicked. Having the same checks applied each time made it much easier to follow.
