I don’t think there is anything wrong with it. I know that for certain events and holidays the local House Rabbit Society will set up photo shoots for people and their bunnies. I’ve done it once before with them for a Christmas shoot. They had a mini carriage type sled on a snowy set, and the bunnies hang out in the sled, but the photographer also knew rabbits, and knew to be quick to keep the stress level down.
I mean the whole thing took less than 10 minutes! I am not sure how long your photo session is, but it is something to keep in mind.
I have a friend who is a professional photographer and she finds that she can get the best photos when people and animals are in their own element and she sets things up in their home or areas that they are familiar with. Her photos are amazing, natural and not “too posed”.
Is this photographer doing the shoot in a studio, or outside or ?? Are you going to have a friend or family member go with you? This may also help with keeping your bunny calmer if she is watched and given attention during the times she is not in the photo.
