I post as my dog Ollie on Twitter, since my handle is his name and the profile pic is him. Example:

Ollie is beautiful!

And think you that he might occasionally post as you? He is, indeed, glorious. When I need to treat my own small, white furballs, I’ll show them his picture.
What a gorgeous dog!!
