My Toby and Lola are going at it as I type this. I worried at first, since he is 2 years older than she is and 3 pounds heavier. I shouldn't have...she sometimes bullies him. They spend most of their day doing this. On the rare occasion they get carried away, one of them will yip a little and it scares the other one so much they stop. I understand about the TV though...they sure can get noisy for little things!!
