So, things were going so well between shadow and the new pup, they even started playing with eachother in the morning. Last night I finally got out to see a movie. I got home, said hi to shadow, went and got the pup out of the crate and took them both outside. They went potty and poop and we came back inside. I went into the computer room to turn off the computer. I was sitting in the computer chair, shutting things down, and shadow came and sat at my left side, wanting attention. I think the puppy tried to get in front of him and lunged at her and actually wound up breaking skin I immediately put him in the bathroom for time out, got the puppy, cleaned her up then took both of them into my room where I pet them and lightly played with both of them at the same time. Then we went to bed. I soooo dont want this to happen again. Any suggestions? Should I only pet both at the same time so shadow gets used to the idea that he doesnt get all the attention all the time? Humph, it was very upsetting.
