Kia là một con ông it's not right. People will understand it but it could be funny because it's not written way.
Thank you for reply. So do I have to use 'con' every time i name animals?
Actually yes but that way no too. But that depends on what you are trying to say. Like "Tôi ân con gà" (I eat chicken) it's accepted too as "Tôi ân gà". This is maybe little bit hard to explain or understand but hope you are understanding.
