Blue was like that. One morning I left him out while I took a shower and I came out to a drooling dog that kept jumping on the door looking in for someone!! We got him in September and with Wyoming weather, it didn't give us a lot of time to get him used to playing outside. Our neighbor behind us has two dogs that he loves to talk to and that is why he now stays out. He likes to taunt them with his toys and dig up Mom's rose garden. I think after time, she will get used to it. We leave the patio door open and let him come and go as he pleases, but most of the time he would rather be out running free.
