Convert your Yorkie or Maltese puppy weight to ounces 16 oz. equals 1 pound
NOTE: An example; 10 week old puppy current weighs 2 lbs. 2oz.
conversion 16 X 2 + 2 = 34 oz.
Next find puppy's current age to the left then follow along until you find 34.
Next follow to the bottom of that column estimated adult weight is 5 lbs.
When in doubt use 3 x weight at 9 weeks or 2 x weight at 13 weeks.
