Very nice. A fair-weather pet owner and a racist all rolled into one, convenient package. You ought to be ashamed of yourself. Your dog's welfare should be the number one priority, not the race of the adopter.
My goodness Jason Leong, you must really keep your brains in your backside. If you need to go to the hospital for an emergency surgery, would you say 'I prefer Chinese doctor'? No, you wouldn't. You would sit down and get the surgery done by any single person with sufficient skill and ability. You are a racist my friend, just accept what you are and make peace with it or improve and move on.
As a side note, dogs are colour blind; you ought to emulate him.
