My Dog. (The picture is my pet dog.)

I have a pet dog. Her name of it is called Baby (or, she is called Baby). I love it her very much. She is a female dog.
She is very cute and young. But every time when I put clothes on her she would become very angry. She will stand still or run into her nest cage, so I will have to coax her.
I love my pet dog!

If we know the gender, we usually use the feminine or masculine pronoun. The apostrophe ( ' ) is used to contract words or indicate the possesive form. The quotation mark ( " ) is used to indicate a direct (exact) quote. They are not interchangeable.
