Well it has been a bit warm up here, to me anyway, as we have no AC and where we used to live AC was on 24/7 and I keep it cold.

I do think she likes to have a bit of alone time. She doesn't appear to be frightened of anything, she's not usually like that. It is kinda cute how she hangs out under there. She wags her tail if you peek under and pet her. I think she might just like her own area. And it's probably a bit cooler, this week has been warm. The dogs have both been sleeping/lazing about a lot more lately. I guess they are like their owner

Thanks for the info guys.
