My new boy, Will, is also 3, and it's taken us (me and him) a little while to figure out the routine. I think he used to go out on a tie-out or something. Curie has always done her business on walks, but he thought this was a bit ridiculous. Walks were for squirrel chasing and hydrant checking! But a few months into it, he seems to have gone along with the plan.
I guess my advice would be to figure out what works for you and them. There is no rule that says they have to pee in one spot in the yard or that they have to only pee on walks or that they have to wear coats or not wear coats or wear funny hats. 🙂
What works for YOU?
(The rain is a drag – I just end up standing out there in the rain with them saying mean things in a nice voice until they get it over with.)
