My bunny is almost 3 months now and loves putting her harness on to go outside!
When I first got her, the breeder showed me how to hold her in a “bunny ball” to show dominance. Basically just holding her in my hands on her, putting my thumbs on her back feet to feel secure, until she’s content.
Eventually she started getting used to that and would behave while holding her much better.
I’ll get my harness ready and lay it out on my lap while sitting down, I’ll then hold her in a bunny ball until she’s settled, then gently, while still making her feel secure and holding her hind legs, I’ll lay her on my lap on top the harness so all I have to do is make sure she lays and then snap the straps together. This got a lot more easy with time because she now understands that when I’m snapping the harness it means play time outside.
You can not “walk” a bunny.
Bunnys walk you.
I usually go out in the grass and just let her hop around.
I let her leash just drag behind bc it never pulls and that way she can go binky around.
