How it works

Enter your dog's weight and choose their life stage and activity level.
Add your food's calories per cup. You'll find it on the bag; see where to look.
Get a daily amount in calories and cups, plus the size of each meal.

The calculator uses the standard veterinary formula for a dog's resting energy requirement (70 × body weight in kg^0.75), then multiplies it by a factor for life stage and activity. Neutered adults use 1.6, intact adults 1.8, active or working dogs 2.0, seniors 1.4, and puppies 2.0 to 3.0. Treats count too, so reduce meals a little if you give many.
