The short answer is yes, a bun can definitely get hurt while wearing a harness. Harnesses can be quite dangerous if a bun pulls suddenly or gets startled while wearing one.

The safest way to give your bun access to the outdoors is to set up a portable exercise pen, and to be sure your bun is trained to return to a carrier on command (even when frightened).

There are some people who will take their bunnies outside on harnesses, but in my opinion this usually seems more for the human’s enjoyment than the rabbit’s, and it probably isn’t a good fit for many bunny personalities. If you do choose to work on harness training, it has to be done very slowly, starting indoors. First the bun has to get very used to wearing the harness indoors, and well trained to come to you and/or to a carrier on command while wearing it.

Here’s a few other threads on this topic with some more info (since this topic comes up relatively regularly on the forum!):

Harness / Leash train

Are Harnesses Safe?

I agree that those who walk their rabbits are doing it more for themselves instead of the rabbit. If the rabbit’s safety and engagement is the first priority, the clear choice is a structured pen outside under 100% supervision or simply doing more engagement indoors with the rabbit.

Supervised time in a pen sounds like a great idea (with the disclaimer that if you’re in an area with RHDV2 you should get your bun vaccinated before allowing time outside). 🙂

My bunnies are both harness trained. I did it because they are very active and curious bunnies. They love it. I take them around the house only because of RHDV2. My bunnies are fine with a harness and it is safe for them because I trained them very slowly and carefully. They have H harnesses which would be the way do go because it put they least amount of pressure one the back if the bunnies was to pull. I also have a elastic leash which would be needed if you do harness train peanut for safety. It takes time and is not for all bunnies. You have to know your bunny, and then pick. Harnesses can be dangererous but so can a pen outside. A bird could swoop down and get her/him, Ticks, and fleas and still are problem. Sprayed grass is a big no and can kill bunnies, so whichever you pick don’t let your bunny on sprayed grass.

Thank you C&O for highlighting that harnesses can indeed be less risky for particular rabbits paired with proper training. At the same time, we must always be vigilant for the exact dangers C&O mentions, like birds, ticks, and fleas.

All very good points! I think some of the commenters in the threads I linked also mentioned that they only did harness work indoors as well.

Some bunnies enjoy being in a pet stroller if you’re looking to go for a “walk”.

If you do pet stroller make sure peanut doesn’t start making holes in the mesh… no escaping bunnies

Just wondering what did you pick to do?
