Be aware that a fox can get into 99% of hutches and can get through all type of chicken wire (if the reward on the other side is worth their time an effort!) There is very little which can be done to keep them away or to keep them from attacking the Rabbits.......so if you want t really sleep soundly and know your bunny's ok then he should be in his hutch in a shed or garage at very least. Personally I'd keep him in doors....we've had plenty of rabbits in doors with dogs and they all got on fine. If anything the Rabbits ruled the roost!
