Chad, Mack is one of the ones that has not done real well with his surgeries.....he has a lot of arthritis and just like Billy's Mum - we handle him like he's made out of glass. Always on leash, no running and playing with other dogs.
One of the "downsides" to this (you probably already know this) is that very often they blow the other leg.....For some reason, I just don't think this will happen with Missy. I have a feeling it was a "fluke" and something happened when she was playing with Cyrus (?) Speaking of Cyrus, that's going to be your biggest challenge in the coming weeks. She's not ready to be turned out to play with him.
I'm waiting on pins and needles to hear how her X rays and follow-up went.
(And yes, I'm the one that's going to be fostering the 4 week old pup - hold a good thought for us. I'm nervous about it...not only is he 4 weeks old, he's the runt of the litter.
