I know it might seem strange, but are there any pet groomers around?
Some dog/cat groomers will do rabbits as well, just a few tips:
1) Ask if they do rabbits.
2) Ask if you can stay and watch what they do.
3) Ask if they have ever trimmed rabbit nails before.
If they say “No” to any of this then I suggest to pass them by, don’t use them. Also ask what nail clippers they use, how they restrain/hold the rabbit.
Once you have okayed a place, they still might not know how serious you are about rabbit safety
1) Show them/ tell them how to pick up a rabbit. don’t say “Usually I pick him up like this.” say something more commanding so they know you want them to walk the talk, “Whenever you need to pick him up, you MUST do it like this, not any other way.”.
2) Feel free to tell them no, you are paying them so if they say “Oh, sometimes we do it this way.” tell them it’s not what you want, make sure they know this.
3) Make sure they have a rabbit safe blood clotting agent, I think “quik stop” is a good one. As accidents do happen.
4) Make sure they don’t put any perfumes or animals near your rabbit.
Hope this helps, I know how you feel, I felt evil the first time I cut Muffins Nails.
