We have 3 Dutch rabbits with a hutch and large run in our paved back yard. A door if the hutch is always open so they have quite a bit of space to run around all the time. We used to also sometimes bring them into our front garden in a fenced enclosure but they kept trying to dig under it and it is a bit of a hassle to set up. If possible I'd like to bring them (one at a time) out to the grass on a lead but not sure if only certain harnesses/leads would be suitable? Thanks
