hi everyone, I am rescuing a berner from a not so great situation. He is a 4 year old named Jim. Jim used to be a family pet, but recently was moved to live outside in a pen. The owner says he was a little too friendly with the other female dogs they own, which is why they moved him outside. I am moving into a new house mid February and will be bringing Jim home as soon as I can. I met Jim for the first time this past weekend, and he was super sweet, however I noticed that he is lacking manners. He is definitely a jumper, which will be something we will need to work on. I have never owned this breed and I am wondering- at 4 years old, will he be receptive to training?
