Not only is my dog a wuss, she is a total biz-itch. - if the weather is bad, she will NOT go outside unless you go with her. - If she is going to suffer the elements, she is taking you down with her. Weinerdog from hell.
Mine is a Weinerdog as well. The week before Christmas, we got 15 inches of snow here. "Jake" WOULD NOT go outside, though he didn't go inside either, for 2 days....
I guess it's hard for a 8 inch high Dachshund to maneuver in that deep of snow....
I took him to the barn, where there was dirt, so he could "go". And he did!

You could have timed him with a sundial....
