Sorry to hear about your pup. My girlfriend and I went through 6 months of rehab with my 6 year old female lab with back to back TPLO surgeries. It was hard with a 6 year old active lab so I can only imagine what it is and will be like for a young, active puppy that has absolutely no understanding of what is going on and whey she can't just run and play like she wants to. Good for you for taking care of her though. One thing about it, they are resiliant, tougher than most people, and bounce back quicker. Keep her away from the incision and watch for infection and she'll be back to her old self in a few months.
