I do a lot of dog babysitting. In fact I have a cavalier king charles spaniel right now. If you ever need anyone in the future, I'd be happy to look after her. I text owners updates and pics twice a day, and the owners are welcome to call as often as they like to check in.
It's so hard to leave our babies!!! I'm 20 minutes west of Indy. Let me know if something like this comes up again.
I'm sure she'll be fine at your friends house.
