The other crating post got me thinking, and this one is a bit different. When I go back to work at the end of next month, Luna will be about 4 months old. I could crate her, but it would be for around 8 hours a day, and she can make it 6 hours now without incident. I have the option of penning her in the back yard. Her pen is about 12'X14' and she will have a dog house in there as well for shelter. I can't leave her run in the yard freely as there are holes in the fence and the mailman ALWAYS leaves the gate open no matter how many times I ask him to close it. The pen area is shaded all day and private so that no one can see her or wander in and bother her. My mom will be home all day, but she is on a walker and can't bend down to the crate or take Luna outside for me. In the future, I will have the fence fixed and move the mailbox, but for now, these are my choices. So, in your opinion, crate or pen outside? BTW - She sleeps inside and is an inside dog.
