We have a new addition to our family. Currently he is a 16 week old GSD. Quite amazing at the amount of stuff he has learned with us in the last 5 weeks. House broken in 10 days. I was a little nervous about a puppy but this boy has been a pleasure to house train. We bought our house about a year ago (1/2 acre). Little info on the home. We are on a corner lot with a 100 acre wetland to our south/southwest. One neighbor to our east about 200' ft away. Neighbor across the road to the NE. One concern I have is we have a minor league baseball field to the north of us with a park towards the road. Basically borders our property on our north side. I just found out from the old owners that they have a invisible fence wire that encircles the entire property. I guess my question comes down to this... will a GSD stay within the yard with a fence like this. He has been great with stangers up to this point. Loved everyone at the puppy classes childern included, doing great at his follow up class too. (his dad was a ham). We bring him on walks around the wetland (frozen winter) without his leash on and he never gets more than 30 feet away before turning and running back to us, even with tempting birds/wildlife about. He was a little aprehensive about the snowmobiles at first but soon found out that he would get to run next to us without a leash and loves it. I even got him on it to ride in my lap. Great way for us to burn off his excess energy at a faster pace than we can go in a foot of snow. I know that a invisible fence is not a impenitrible barrier for him but is it possible to train him to stay in the yard given his temperment so far. Obviously he will not be out there unattended but if the wire is in already and we can hook up a head unit and collar for just about nothing is a feasible alternative to a fence as long as we are out there with him. About the only thing he will growl at is another dog (they usually start playing as soon as they sniff one another) and I have yet to see a dog come to a baseball game or the park next to us. Is it common for GSD to make a break for it and go through the IF? any thoughts are appreciated.
