Thanks guys. I think we may stick to one for now. My only concern that was because we work, it will be on it's own after the initial time off I have to spend with it. But we are very active after work and will be exercising it daily and taking it every where on the weekends etc.
Shoemonster - your staffys crack me up. Whenever you talk about them, I can picture them as my mum has a staffy with the same colouring and all and I just laugh. Gorgeous!
