Hi all- It’s been forever and a day since I’ve posted in here!! so the big news is that I am making arrangements to go meet (with a harness, leash, and name. Oh and check book ) a puppy that was co-bred by Watson’s breeder. She is a 10 week old Tri who they think is going to be oversize- around 17 inches is their guess. I did a forum search for oversized and didn’t come up with any results. How big were your oversized puppies when they were this young? Watson is right around 15 inches. Two inches doesn’t seem like much but I can’t picture just how big of a sheltie that would be. He weighs in at 20.2#. I’m thinking if she is around 17 she will probably be 25-28? Is there a formula for pounds per inch? Or a growth chart to see where she might land at her adult height? Or is sheltie height just too unpredictable?
