This is a great lesson in my view and really appreciate sharing it. Dogs are reacting differently to sudden wake up from their deep dreams, just as humans and always good to learn it.
Miksa sleeps in the crate per his choice, and the only thing startling him is a sudden noise coming from outside. Then he has a high pitched bark, followed by getting my hand to lick at thru the crate and an all is well, back to sleep in 20-30 sec.
Bende if he sleeps in crate reacts to sudden noise from outside the same way as Miksa. If falling asleep on couch, floor or bed, when i walk by, he spreads his legs and is ready for touches, especially liking chest area and face rubs.
I respect my boys preferring different sleep habits, i have the space to accommodate it and at the end of the day, we all want to minimize stress and enjoy life as much as possible.
