When we first brought our younger german shepherd Kane home, Jax (our older GSD) was ecstatic to have a baby brother. Jax didn't want to let Kane get out of his sight, but we did make a huge effort to keep them apart for most of the day; while we trained Kane. Now, at 8 months and 17 months old they are as thick as thieves. They do stay pretty much apart at home, Kane with me and Jax with "Daddy". It's easy to tell whose dog each one is. The only time they hang out together is when they go out to play (our yard is almost an acre large) and when DH and I are in the same room. When they go outside the first thing they do is Jax patrols the fence line, Kane patrols the house perimeter. This isn't something we've taught them, just something that comes naturally to them. We took them to town last night and ran into a problem. After riding around for awhile we stopped at the police dept. so DH could talk to a couple of his officers. Kane loved on both officers when I let him. Despite the fact that Jax is used to the uniforms and liked the one officer, he definitely didn't like the other, younger officer - the officer was showing alot of fear. The problem we ran into is that I couldn't take either dog for a walk around the PD parking lot without the other dog getting very upset. I would like to take the dogs for walks on our farm, rather than them just playing in the yard, and Kane needs the walks because of his weight. I can't take one without the other getting very upset. Due to my handicap, I can't handle two large GSDs at once. I guess I failed dog training 101 that they can't be seperated without pitching a royal fit.
