Luke almost always keeps his brown eyes on his owner Kathy. When she raises her right thumb (大拇指), Luke knows he’s been good. When Kathy holds her right hand in front of Luke, he sits. Kathy uses hand signals(手势) to train Luke because he cannot hear.

Training a deaf dog can take more time than teaching a hearing dog. An owner must use signs to give commands (命令). Some owners use American Sign Language, and others make up their own signs. Like hearing dogs, deaf dogs should first learn to sit, lie down, stay, come, and stop. Other commands can then be added one at a time. Luke is just one year old, and he knows 20 commands!

To get Luke’s attention in the house, Kathy stomps (跺) her foot. Outdoors, during daylight hours, Kathy waves at Luke until he notices her. If Luke is in the backyard at night, Kathy calls him by turning the porch light off and on. Luke also wears a bell so that Kathy can know where he is.

It’s also important to know how to wake up a deaf dog. To wake Luke, Kathy holds her hand in front of his nose. She lets her smell wake him up so that he won’t be frightened. If Luke is sleeping when people visit, Kathy asks them not to wake him.

Like most deaf dogs, Luke gets nervous if he doesn’t know where his owner is. He’ll walk with quiet steps from room to room, looking for Kathy. Before leaving a room, Kathy makes sure to get Luke’s attention. Sometimes Luke follows her, but other times he just sighs and goes back to sleep.

Kathy and Luke spend about 15 minutes every day working on old and new commands. With his tail wagging (摇摆) and nose wiggling, Luke looks as if he’s playing instead of working.
