Yeah, good luck with them not eating anything stinky…..lol
This might not work for your dog......but I've found that with both of mine.....the secret to keeping them away from something you don't want them to get into is just to let them go at it.
My dog used to get into the litter box and I'd make a big stink about it, squirt them with water, treats for not going into litter box......didn't do much to make them stay out of it.
So, after reading some advice I found on this forum, I decided to try an experiment and not bother to get mad at him for getting into it.....sure, found cat poop on the stairs for awhile....but eventually he stopped getting into it altogether. Ever since I've used this technique on both dogs; getting into my socks? I buy them a ton of thrift store socks, let them go nuts. Bags? I give them safeway bags. Kleenex, unripping pillows, etc.
For me it's worked in my favor. I may have dogs that are exceptions to the rules but I've found that the less I tell them to get away from something, the less likely they are to get into said object. If there is a weakness they will target that weakness until it is thoroughly destroyed. Lol.
I could see that going seriously wrong with the wrong dog though......but, in my mind, I would rather them get their fill now then get into something dangerous or expensive later when I'm not looking. Of course this won't work with everything. Certainly wouldn't try this with anything that could potentially kill them....and always supervised.
Anyways, Rabbit poop can't be too dangerous right? Better rabbit poop than horse poop......But if it really bothers you... A leave it command.......or possibly pick up some rabbit dung and spray it with bitter spray....let him see the rabbit poop and see if he garners a negative experience from it to the point where he won't bother with them?
I've never done it, but, I have heard of people having a lot of success tying shoes around a dogs neck and leaving them there (if they chew on shoes and don't respond to reprimand) so maybe you could tie little rabbit turds onto his collar? [I'm seriously kidding about that last one. No rabbit poop collars.]
That's all I've got, lol.
