Breintje is our Netherland dwarf bun. He will be 4 in a couple of days, and he has been with me for nearly 2 years now. He’s been snipped a year ago. Lately we noticed a change in his behaviour: normally he was too active to lay flat. He was always a bit skittish and startled easily, which a lot of people describe as common for this breed.
Lately we’ve seen a change in his behaviour: nowadays he lays on his side or outstretched so often, we’ve started to wonder why 
He’s eating, pooping and running around normally. At first we thought he had tummy troubles, but he seems totally healthy. This morning he ate his pellets and rolled over afterwards. He just lay there for several minutes with his eyes half closed, completely motionless. I checked if he was breathing, because this was new… But he seemed to be doing fine, and I could even pet him. When I petted him, he closed his eyes and made a smacking motion with his mouth. This is really odd behaviour for him, because normally he’d jump up at any sound. Even the sound of me getting up from the couch, so walking up to him and petting him was really strange. He felt rather floppy, but was active and hopping around afterwards.
Everything may be OK! My two Flemish girls (10 months old) often sleep on their side. Sometimes moving to sleeping on their sides is dramatic. If they are setting up, they may sort of jump slightly in the air and dramatically flop over laying on their side like they had just been shot dead! I’ve had experience with sleeping dreaming bunnies. If your bunny closed his eyes and was smacking his lips, he was most certainly dreaming. My previous rabbit Bunny, would drift into dreaming when I would pet her while she laid on the floor beside me. Laying on her side, sometimes her front feet would be shaking, her eyelids would be fluttering, and she would be smacking her lips. Once, while she was dreaming like this, I stopped petting her because I thought I might wake her up. About 10 seconds after stopping petting her, she jumped up, growled, and slapped me with her front feet! I WAS A BAD BUNNY! My job as a bunny was to keep petting her telling her bunny brain that I was a bunny keeping an eye out for predators! When I stopped petting her, her bunny brain told her that I was asleep and no longer watching out for predators! That’s why she was angry and woke up and slapped me and growled at me because she thought that I may have fallen asleep!
I really enjoy living with house rabbits! Our Flemish rabbits are PBB’s! Pretty Big Bunnies! They are now 10 months old and live running free in our house. (We don’t let them in the bedrooms.) We have pen for them in the living room and they do spend a lot of time in their pen, even though the door is always open 24/7. When not in their pen, they like to sleep under the curtains and at other hidey places in the house. We have had a free running rabbit(s) in our house for over 12 years now!
