My little girl had the op done on both her back knees and she bounced back like a trooper!...
Christie was a toy poodle and verrrrrrrrrrrry opinionated,so her 6 weeks of rest where a battle ...but it was worth it,her quality of life improved and she was much more mobile and pain free....
Its never going to be easy keeping an active paitent quiet but....i will say Christie did cotton on to the fact she had to 'take it easy' and yes we did have another poodle in the house who intially wanted to play,but he got the message too,and gave her the space and time she needed to get better.
I dont think it will affect your little girls personality being restricted fro a while,you just have to be firm with her,and loving
It will be worth it!
