This past weekend, while I was in Atlanta, my Jack Russell, Finn, tore her ACL in her back left leg. She was running around the yard chasing my other Jack Russell, Zella, and suddenly yelped. She had torn this exact same thing two and a half years ago in her right back leg (see photo). Poor thing. So, we're going to schedule another surgery for her in the near future. She's hopping around on three legs now, which the doctor said was fine.
