I have known about the puppy growth chart since I got my first yorkie, Cash, more than 3 years ago, but I couldn't follow Cash on the chart because he was off the charts!! He is a whopping 10lbs all grown up and I love him for it.
But when I got June, my 1 year old, she was a teeny weeny puppy at 21.5oz (600g). I could follow her on the chart and it was spot on! She is a healthy 4lbs adult, exactly as the chart said.
I was wondering how often the chart is correct? How many other owners' puppies followed the chart?
