I'm sorry, but I'm talking about transferring the dogs, not simply dogs in an enclosed kennel. There had better be some kind of collar on the dog when moving her around, or "walking" her, etc, but I'd prefer a choke specifically.
A good kennel is set up so that you open the door to where you want the dog to go and you open the door to where the dog is and it forms a hall of sorts so that the dog has no choice. I agree that a choke is best in any situation involving a leash.
