"Daddy, I want a male dog. Can we have a male dog?" "We’ll see, but why not a female dog?"
A male dog is a male dog. Do you know what a female dog is?
The readings are the kun'yomi readings, which is probably A-Okay for 犬, but for 雄 you'll want to think about how a male dog is probably pretty pushy, always trying to push (押す) other dogs around, being male and moody and all that.
