So, my 2 1/2 mo. GSD seems to be a bit obsessive with my almost yr old sibe. When I walk him by himself, he's amazing and will Heel right by my side. Training him is so easy, but the only downside is whenever my older dog is around (wether we're walking him or letting them run around at the park) he HAS to be next to her. If my wife and I separate them he'll whine like the world is ending :P
I'm hoping he will grow out of it as long as I keep occasionally walk them separately to the park and put him in a short puppy time-out.
Any suggestions? Thanks in advance!
