Dog size/growth estimates for a new backpack

Aurora is 11months old and approximately 65 pounds. She stands 24" tall, 22" long from neck to base of tail, and 29" girth at the widest point of her ribs. I want to get her a pack and the sizing is as follows: Girth M-23-36" Girth L-31-48". I'm wondering if she would eventually outgrow the medium and if anyone has a dog that was comparable size that they could measure? Any other recommendations?
