She is resting when this happens. No physical contact with anybody. Just doing nothing really. As I said, sleeping or napping mostly.

Hi- She has done this once every day or so lately. We thought maybe it was as a result of a dream, but just now it happened when she was awake as well. It sounds much like when you test a smoke detector and with the same intensity, or a ULTRA-loud squeaky toy's single squeak, and she shows no physical response or reaction upon making it. We want to comfort her immediately but she doesn't seemed bothered by it at all - as if it didn't happen. Has anyone else experienced this or have an explanation?

@alibobo She is QUITE warm - as you said, like a hot water bottle.

@jengosmonkey Nice black and white basenji there - the straight tail indicates it is very relaxed. Maybe the breathability of chain mail is a point in its favor - thanks for the tip. Maybe something in titanium. It would also help dull those mouthy teeth that she has (she's a puppy).

@elbrant Draping her crate (which she likes) is a good idea. We like to sleep under blankets with cool air, hence the cool bedroom.

Our puppy sleeps in our room with a warm pad under her crate, but gets cold nonetheless because our bedroom is unheated. We tried a knitted sweater, but she had it off and was chewing it apart. Any ideas for something durable?
