A Slightly Bigger Door

It didn't seem like that big of a deal to me. The flap of the dog door was torn and needed replacing. I couldn't find just a flap, so I bought a whole new door. Since they had them in extra large, that's what I bought. The old one was just a large and is hard for big dogs to use.

I put in the new door and left for work. When I got home, there were three large puddles and three dumps on the carpet. It never occurred to me that the dogs wouldn't know how to use the new door. Heck, it's just like the old one, only bigger. What's the problem?

Now, I have to train them and shampoo the carpet.
