When I go out with them (it's important to go out with them, rather than put them out - you need to watch what they're doing!) I'm very jolly and say nonsense like "Out we go! In the garden!" in a cheerful voice, then keep a close eye on what they do. When they start to wee or poo I'll calmly repeat "Busy busy" (if weeing) or "Hurry up" (if pooing), then when pup's finished give lots and lots of praise. I don't give the command
before they've started doing anything until they've learned what it actually means.
