Morgan just learned about 4 months ago how to jump up on the furniture. Bailey the little Yorkie I just got, (he just turned 4 months old), can now jump out of his playpen, (the playpen only lasted about two weeks before he could get out of it), he jumps the baby gate and now goes up and down the basements steps. I am just so glad Morgan hasnt' decided to see if he can do the things Bailey is doing. I will be in deep if he ever does! lol
