Who let the dogs out?

I did.  When my son-in-law and daughter know they are going to have unusually long days away form home and their kids are also gone they ask me to come and let their dogs out sometime during the day.  I do it whenever my schedule permits because I wouldn't want to be shut up in a cage all day without a chance to use the facilities.  Today was one of those days.  I imagine them anxiously waiting for my visit but today they didn't even wake up until I was in the house and had opened the back door.  I like to offer them quick egress.  I will say this has been a learning experience.  I used to think keeping dogs in cages all day sounded cruel but these two seem to appreciate the security.  After an hour of free time, in and out of the house, I tell them it;s time to go back in their "houses" and they just walk right in and wait for me to latch the doors.  All very nice but, take it from me, cats are still easier.
