When you put the collar on the dog, make sure the receiver is sat underneath the dogs neck out of the way, rather than sitting on the back of its neck. shouldn't get in the way then.
All the best.
The b&f collar naturally sits on the side of the dogs neck.
Well I'd say sit it unnaturally underneath the dogs neck out of the way.
I assume youve not put one of these collars on any of your dogs. Might be reading it wrong, sounds like you want an argument, so ill leave you to it.
