From the porch into the front door there is a step of about 10 inches and Diego stands there rocking back and forth because 3 years ago he slipped on the wood when it was wet. I have grip strips on it now and he can't slip but he still will not step on that, so I have to get behind him and coach him, sometimes loudly. Lately I just started picking up his front half and setting it down inside the house and boy does he hate that, but it's better than standing there letting all the cold into the house.
