Frankly, wherever he happens to be at the time he decides he needs a nap! Right now, he's asleep -- and snoring -- in the space between the chair and the sliding glass doors. Another favorite spot is under the end table next to that chair!
For napping during the day, Finn loves snoozing very close to me, on the sofa. Tate loves the sofa in my bedroom--he gets that all to himself and the sun shines thru the window so he gets to sunbathe at the same time.
When they are out during the day, they love to nap on the carpet, or on the couch beside someone, but at night they snooze in their crate, I don't think it's their favourite place though. Lol. They prefer to sleep snuggled up beside me or anyone else on the couch or by your feet on the carpet.
I chose several here cause she's not picky. Ruthie sleeps on her daddy's couch recliner all day. At night, she's in bed with us. She loves her crate too. The only place she won't sleep is on the floor or somewhere out in the open. She HAS to have her back to something.
