I guess bunnies are not natural water babes.
I found this on line on bathing bunnies and thought you might find it useful.
BATHING
We do not advise flea baths or baths of any sort for rabbits. Bathing a bunny can often cause her to become quite upset, sometimes causing her to go into shock; plus it is the nature of bunny fur to take a long time to get wet, and an even longer time to get dry. Spot bathing extremely dirty areas (feet, scut, etc.) is the way to go. If you use a hair dryer, us it on low to medium heat so you don't overheat the bunny, and keep it at least 12 inches from her body. Don't use it on her head, ears or privates. Sometimes bathing is necessary. In these cases, do it in a small sink in warm water. DO NOT EVER immerse entire bunny (water level should never be higher than belly level); instead, let bunny stand on hind feet while you support her upper body from the front. Slowly let her put all four paws into water. Use a cup to soak and rinse body. Rinse thoroughly
I love bunnies.
I remember when I was a guide for a Spanish travel company, picking up some passengers from the airport.
One young Spanish boy could not understand why when he went into a pet shop and asked to buy a rabbit the owner of the shop refused to sell it to him.
It could have had something to do with the fact that he explained to the owner in his near perfect English that he was staying with English friends and wanted to prepare a paella for them and the rabbit meat was always better if it was killed fresh that day
He still didn't understand what the fuss was about when I picked myself up from the floor onto which I had fainted with shock ( not really but that is how I felt) and explained to him how as an animal loving nation we would find that quite abhorrent.
I know we eat lambs etc, but somehow bunnies and horses just do not seem right.
Hope your bunny is well and feeling refreshed.
