I had tried to bring one of my two year old labs into the house recently. Cody went insane. He was terrified. She just wanted to play but it scared him alot. He just hid and when I took them outside to go potty he was growling and barking and then he jumped up and grabbed her throat and was growling and biting! I was shocked I've never seen him aggressive towards anything! She just looked at him like "what is this thing?" I'm sure it would have worked out if I had the time to work with both of them but I was overwhelmed at what had happened. So my lab went back into the pen with the three others (I think she was thrilled to get away from the thing that was crazy) and Cody went back to his normal self. If you work with both of them and watch them closely it should work. Just be patient and work with them both.
