My yorkie Betty is also very excitable. She is about 4 1/2 months old. She's excited when she sees visitors, our other dog (Border Collie), our outdoor cat, etc. Also, when I play with her, she gets super excited and runs around in circles to work off her energy (which is funny). The down side to playing with her is that she BITES in her excitement!! And it hurts. I try all different ways to get her to calm down or to bite more gently...today I was desperate and I even bit her ear a tiny bit (like our cat does)
I think they understand that better than yelling "NO". It was funny because when I did that, she backed up about 2 feet and stared at me. It was like she understood. Who knows?
