I fit the harnessmore snugly around her chest, behind her front feet than I do aroundher neck. In most cases, rabbits will try to "escape" not by runningforward, but by backing up to shrug themselves out of the harness. Thepart of the harness around the chest prevents them from shrugging out.It gets "caught" on their front legs. The part of the harness aroundher neck keeps the part around her chest from just slipping off herback legs. OK, I'm rereading that and I'm not sure it makes sense.Maybe someone can make it a bit clearer.
In any case, I never ever ever ever leaveher unsupervised on the lead. If she even starts to look like she'sgoing to try to back up and shrug out of it, I stand close to her soit's not possible. If she continues to back up, I pick her up for aminute or two, and then set her back down when she's calm. I startputting a harness on my buns as soon as I get them, so they areaccustomed to them from the time they are with me. However, if you'restarting late, and you need to get them used to how a harness feels,you may want to put the harness on the bun in the house or in anenclosed area outside. Wrap up the leash so it's not trailing behindthem to get caught on something, and let them hop about a bit for alonger and longer period of time each day without you pulling on it.Then start to hold the leash for short periods of time, until they areused to you being at the other end.
