Canidrome had given Garlic to the kennel early last year, according to the Civic and Municipal Affairs Bureau, the local government department that runs the facility. Two other greyhounds found new homes the same way last year, it said.

The department said it had asked the track operator to provide a plan for “rehoming” all of its dogs but that it had not yet received a response.

Ms. Lam said Garlic was “very, very shy,” and had initially barked in her sleep in what Ms. Lam interpreted as nightmares. Though the dog is still scared of the benign ocean waves on the nearby beach, she appears to have taken well to her new home.

“The truth is she is just like furniture,” Ms. Lam said, describing how Garlic spends much of the day sleeping in the kitchen or watching the family and their other two dogs’ every move.

Ms. Lam said no one she knew would approve of dog racing these days. “All my friends are against it,” she said. “The younger people do not like that kind of cruelty.”
