Does anyone know where to get the Gucci Dog bag?

I'm going to be a first time Gucci buyer and deciding on what my first bag will be...then today I saw this one girl holding this bag:

And I fell in love with it. I went on the Gucci site and I can't find it. Then I try to search online and it all gave me this a real bag? and if so, where can I find it? Thanks!
