Thanks for the clarification Bildio---that makes this Yorkie momma happier. If I follow your math, you multiply the number behind the decimal by 1.6 and then add that number to the number of ounces in the pounds (1lb=16oz, 2lb=32oz, etc.). Is that right?

So in my case Dipity was 1.7lbs. 1.6x7=11.2 add that to 16oz (her one pound) and get 27.2oz total. Then take that number to the chart.
Thanks SO much for pointing that out!!!!
Perhaps this will help someone else too. Blessings!
