We have just put a deposit on a two week old female Siberian pup. While I am without a doubt she will be a wonderful sister to our 17 month old Bernese Mountain Dog and an incredible addition to our family, I have some serious reservations about the breed. My husband, who had Sibes growing up, strongly requested that if we got another pup, could it be a Siberian. Here are my concerns: we live in a rural area of PA in a large home with a two acre fenced in yard. Our house is on a corner of a small, but busy country road. Our fencing (about 4 3/4 feet high) consists of posts and rails with strong chicken wire surrounding it and it's dug into the ground about 2 inches. Our BMD has no interest in getting out either by jumping or digging - Sibes on the other hand are master houdini's. Our BMD uses a doggie door to enter the yard as he pleases, and I am very confident that if I run a few errands or am gone a few hours that he'll be there when I return. I don't think this setup will work with a Siberian, will it?????????
