I love your domain name, dogmama!

Just make sure your web host service already hosts wordpress.org blogs and ask them for their customer links. The free one is on wordpress.com on Wordpress company servers....

I have used both versions. What wordpress.com version does is to make sure its core/new features work..before they take to .org version.

I have used both versions. There is inherently some strong advantages using wordpress.com ...for free to try out. It doesn't hurt to try your own personal blog separate from your business.
