Could you get a family member to take care of your dogs if the heat embargo is still in effect on October 15th?
As for the crate, have you tried a bigger crate? My dog really didn't want to go into the crate that "should" have fit him (albeit barely). He'd go in, eventually, but immediately come back out. When I tried one size up he was quite happy to get in and stay there, so I think having the extra head room helped him.
Good luck!
