Thank you all. I'll be sure to tell her that PT is mourning with her.

Catty - I can tell my sister is having a hard time dealing with her emotions over the dog sitter. Her comment to me was "I know he feels bad but I can't help him with that, he has to deal with it just like me." I kept telling her it was just a strange sequence of events. It's the first time ever that Lucy has wandered out of the fenced in yard because she is very skiddish. Even when their other dog, Rudy, got out before Lucy didn't follow. My sister feels Lucy went out looking for her which is making it even harder on her. It will just take time to heal her heartbreak.
