You will end up doing most of the work, so you have to want the dog too.
There is a lot of return on the work you have to put in. That dog will love you possibly more than anyone else in the house. I'm the alpha to the dogs...they adore me. They drive me nuts but I get lots of doggie snuggles and it's an excuse to get out and take a walk when I'd rather sit down and veg.
I think dog sitting would be a great intro. AND...if you decide to get a dog, I'd adopt an older already potty trained dog instead of a puppy. Having a puppy is like having a newborn. You REALLY REALLY have to want that.
