can a dog be a bitch??

Even though Ah Boy is a male, he's such a bitch!!!!
I made barking noises
(for fun.i'm not wacko)
and he just sits there and doesn't respond.
But the moment I whistle
He starts barking.
wth!!!
I ought to stop feeding him.
See he still dare to bark or not.
Bitch man, him.
LOL
