I have 4 inside(2 outside) dogs. The newest one came home back on November at 5 1/2 mos old. I put her down and let the other ones smell her. The oldest one(11 year old shih tzu) wanted to start playing with her right away. I always bring new ones in, put them down, let them smell eachother and let them all play. Of course, I do stay right in the room with them |
