I was a little apprehensive at first. Like you, I thought about it and almost did it several times. Then, I finally got Tyson, my white rescue. It's been four months and I must say, it gets better and better. It's just me here, so even though they require attention, its what I do. They are my kids. I walk them every day, but also have a fairly big yard so it is not a burden if I can't get out one day. I would think with your situation, you should go ahead and do it. It sounds like you really want one, and are taking things into careful consideration. If you had not posted about this before, I would caution you to think about it. But now, I say go for it!
