Dog height is measured at the withers, which is the highest point of the shoulder blade. On a thick coated dog like Koda, you may need to compress the fur to get a more accurate measurement. Here we are using a yard stick which you can pick up in the paint department of big box home improvement stores.
Koda’s height is measured to be 20.5″. He’ll use a 55cm ball based on the NATE size chart.
Wikihow has an alternative method for measuring using a marking on a wall.
