The trrouble with that calculator is that it then below says you should use a factor of 3 for puppies under 12 weeks so that is too much?

This calculator warns:
The Dog Food Calculator was designed for adult dogs only — not for puppies.

Typical calculators multiple the ideal weight in kilos by a factor of 70x.75 and then times 3 for a puppy ration.

The Acana package is the problem, at 150 to 300 calories perday
