My DSD is going to bring her full grown, large spayed female to meet Jax tomorrow. Her name is Domino and she's fairly dominant. Though we've socialized Jax (GSD, 7 mo. old) heavily, he's never actually met another dog. We live on an isolated farm and he just hasn't seen many dogs and never up close. Yesterday on our walk he came close to meeting a great pyrenees, a bassett hound and two dachshunds - our closest neighbor's dogs that run loose. They wouldn't cross our cattle guard to get too close and Jax doesn't cross the cattle guard on our side. I had him leashed. Jax bowed up, with all the hair on his back standing up. He sounded ferocious! but paid attention to me as we walked away. Any tips on introducing Jax to this female? We will have both leashed, of course and will start with the female outside the fence. I'm concerned because Jax is very protective of our yard. He needs to start getting used to other dogs!
