Hello

I am sure an older dog from a shelter would be the best. I think most shelter/rescue centres work the same way in the Canada and USA as the do here in the UK, they will try and fit dog to home and person as much as possible. Over here some also encourage current and new dog to meet first to see if they maybe will get on too.

Anyway, that is what I will do if I ever need to find a new furry kid!

Good luck.
