I understand that it must be tough to keep a Jack from wanting to run and play.
Hopefully you are taking her outdoors on a short leash to help prevent her from running.
Whenever I've had pets recovering from surgeries, I've found that letting them have a very
low level of pain will keep them from jumping around too much. If they get a big dose of
pain killers and are totally pain free, they want to jump around and can re-injure themselves.
I don't believe in letting animals suffer with pain, watch your dog closely, she will let you know. Best wishes!
