my baby boy is 14months old..I was wondering if this has happened to anyone elses yorkie..Ive always had to carry him down the stairs..He would go to the edge and wait for me to pick him up and carry down..Well the other day I couldn't find my baby because he had escaped through the kitchen door and went down the stairs by himself..I laughed so hard as he was waiting on the first floor for me..Now he zips down the stairs..it only took him 14months to do it!!
