Cloey is 4 pounds and she is sooo fiesty.. she will jump on anything.. even if she can't reach it.. she'll jump right into it and bounce off.. she'll jump off anything as well.. she jumps off my boyfriends bed which is pretty high for a small pup like her (shes 4 months old).. and my Porkie Oreo has just recently taught her how to jump over the baby gate.. so both of them are climbers!! means i got to get a new gate or something!
