"One thing we like is good natural dogs that think for themselves.
"We don't like robots because in a pressure situation they have to be able to think for themselves to get us out of trouble."

"I'm at that stage of life now where I've had to semi-retire and put Mask up [for sale]."
Ballantine said he was glad to see Mask was going to a good home.
"I'm rapt where she's gone to. She's a very special dog."
Nearly all the dogs were sold on the day with some buyers coming from as far away as Amberley in North Canterbury.
