Had an opertunity to spend a night in a wood this weekend, so I grabbed it with both hands. It didn't look like rain so I only put up a tarp rather than use my bivvy bag. It was the first time bivvying with the dog, but it went well, although I think she was a little cold at times. The plan was for her to sleep on the rucksac but she ended up on the camp matt next to my feet - I guess she was more out of the breeze there. If bivvying becomes a more regular activity I think I'll have to sort out some sort of tarp/groundsheet/bed arrangement for her.
