I have to go out of town for work for three days and two nights. my dog is staying with a friend, who works 8 hours a day. i don't want to leave him out at her house because he does have separation anxiety if he is not home, and he has never stayed at her house without us before. So, he is going to have to be crated for about 9 hours a day for two days straight- is this completely horrible? really, i'm looking for people to reassure me that it's not, because i feel pretty crappy about it...
