We measured the girls in class a couple weeks ago so I could be sure of their jump heights, and Sass was about 20.5, while Cookie was about 21.5. Chloe is 22 even so they are both shorter than their mom! Dad is about 23, I think. The funny thing is, people in other breeds all tell me how much they LOVE Sass’s size and are very disappointed when I tell them she is under standard.
