My puppy dog likes to snuggle on the bed in the mornings though I usually get up and let her out for a shetnapiss first. And then we both leap back into the bed - though she's only allowed on the bedspread not in the bed. There were a few times I got up and I opened the back door to let dog out, and I went to the dunny but when I got back to bed, she was in the warm spot I'd just vacated. I was not happy. Now I make sure I pull the bed covers right up any time I get out of bed.
If Frosty wets the bed - I'm up for a new mattress cos there is no way I'd get that out of a cotton futon.
