Neither one of mine will go out in more than a lite rain unless they're desperate. They have to be hurting bad before they'll go outside to do their business in the pouring rain. At least the one with the peanut bladder will use the doggy door so he'll jet out when ready. The other won't use it because she's really spooky acting but when she's ready she'll tough it out in the rain and make it quick. They'll both get in nasty ditch and pond water though
The spooky one musta been hurting because she finally went out.
