All 4 of mine will go out in a storm. But just to pee. The other takes too long! Gracie is usually out and all the way to the back of the yard before she even realizes it is raining. LOL
They all use pee pads if they can't hold it but they also all prefer to go out so we keep them on a regular schedule.
With Cassie getting old and Gracie never having been house trained till she came her at age four - the two of them are using the pads more and more. I truly wish we could put in a doggy door but they would have to go through three of them to actually get outside. (garage, utility room then back door.) sigh. One of these days I'm gong to have someone install a door in my office and then go crazy with a fenced-in covered run for them. Of course I will have to use the insurance money I get from my dh's "over my dead body" policy. LOL
