I'm new to this site as a member, but have been reading the forums for a while and am excited that there are more women cropping up with similar plans of cruising, even alone!
I have a dog too, an english cocker spaniel, I haven't worked out the details on how thats going to work, but others have, and so will I. A good read and well rounded book on cruising is The Cruising Life...A commonsense Guide for the Would-Be Voyager by Jim Trefethen.
I have a career, two homes, etc., but my spirit is already out there cruising. I've even announced to my closest friends and family that I am no longer buying anything that won't fit on my sailboat. I've decided not to purchase one until I am ready to shove off for good, and if you read the book, you'll understand why.
Anyway, much success to you and a big HI Five to seeing more of us out there!
