In deep rest, a bun can part their lips so the front teeth show. You can look at #bunnyteefs on Insta for some examples.
Its obviously important to keep a close watch on those sneezes. Theyre as a rule only sneezes (hay dust etc), unless you see thick snot (opaque white or yellow-greenish etc), but its definitely good to keep a bit of an eye. (I cant think of a time when it wouldnt be good to keep a bit of an eye on a bun’s general health though 🙂).
A bun with distressed breathing will often sit up, in loaf position, with their nose pointing slightly up. Lying down compresses the lungs (rabbits have small lungs compared to rest of the abdominal organs), so they tend to not want to flop if they’ve trouble breathing. Frequence of breathing is 30-60 breaths per minute in a healthy bun (they’ll breathe faster after exercise, just like us).
Eclipse is still quite young, but she’s past that very vulnerable baby-age.
