This is a rough guideline. Adjust to the dogs individual needs. Too lean then up the amount. If your dog looks a little porky or refuses food then reduce slightly.

 Puppies at 8 weeks old should be on 4 meals per day reducing to 3 at approx 4 months old and down to 2 at approx 6 months old.

Adult dogs are usually fed between 2 -3% of their bodyweight. This can be upped or reduced depending on the dogs needs.

Elderly, less active or nuetered animals often need less whereas energetic or working dogs can need more. Keep an eye on your dog and adjust as necessary.
