What do you write in a blog?

Blank screen. Blinking cursor. What do you write in a blog?

I write about my dog, Lexi GenreRain Denison. I specifically write about her hair. It is black, white, and very nappy. There are a lot of knots. I would brush them out, but she won't let me. She has a very sensitive scalp with a lot of fine hair. So that's what I write about... Lexi and her beauty.
