For example, if you have a puppy that weighs 4lbs at 14 weeks old the math would be 4/14 = 0.29 X 52 = 14.86 lbs as his adult weight. His growth rate is how much weight he gains in one week and is calculated as his current weight divided by his age in weeks.

If your puppy is in-between two weights for his age then you can find the average of the two.
