I think it is in the 30's right now, which is super cold for Louisiana. I think the colder it gets, the more mine LOVE to go outside, and the longer they take! It seems as if one is always standing by the back door wanting out.
We have a doggie door cut in our screen door, so we open the door and wait for them to potty and let them back in before closing the main door.
Sometimes Cooper fakes having to potty so he can run a lap around the perimeter of the yard, barking his head off the whole time...when he comes in, he jumps in my lap, and he feels like a chunk of ice. I think my babies are really Alaskan Malamutes
