I have a 2 and a half year old Mini Australian Shepherd male dog(fixed). 1 month ago tomorrow, my 1 year old female German Shepherd was killed by a car. That being said, we are getting another puppy within the next couple months. I was wondering if anyone had any experience with 2 male dogs of different breeds? My Mini Aussie was really good with our female GSD. He never bit at her or got aggressive. He lets out kids (2,4,5) do whatever they want to him and has never shown aggression towards them or anyone else. However, he did pee on the floor when we brought our last puppy home! LOL. Anyways, we were thinking about possibly getting a male dog this time. I wanted to know if anyone has had any experience in this situation. Will bringing a dog of the same sex home as an 8 week old puppy increase the chances that the males will get along? I have had 2 female GSDs that hated each other so much that they became aggressive and had to be removed from our home after a fight that broke out causing me to be bitten. Would a male GSD act different with kids? Our female let my 2 year old daughter use her as a pillow, and she was very good at following the kids around watching them all day. I attached a picture of the GSD we had, which we miss alot. The house feels really empty without her, so we want to make a decision on a puppy soon.
