Both of my furbabies love being outside regardless of the weather.
Napoleon will even stand out in the rain.
It has been pretty cold here the past few days and I am really having a hard time making them come back in the house. One day last week when it was pretty cold out, they wouldn't come in and I had to go to work.
I had to leave them out until my son came home. It was just a couple of hours and they have a doghouse but I still felt really bad for having to leave them out. They are perfectly safe in the backyard, I have made sure of that, no bad plants, they can't get out and nobody can get in, etc.
My son said when he got home they came in, rested for about 15 minutes and wanted right back out. They stayed out for most of the day even though the temps were in the 30's. When they finally came in, they just wanted to eat and go to bed.
I guess it is just whatever they like to do.
