My Tucker doesn't have another dog to get into it with but his best friend next to me is Nicky the cat who is just a month or so older than he is. Even though they always play pretty rough, every now and then, its like Tuck becomes a rabid wolf or something and attacks Nicky so fiercely it is scary. I don't know if its like a reminder of dominance in the household or what but EGADS!! it sounds like a tasmanian devil or something when it happens...
