Bailey is 4 1/2 years old. He has always been pretty good, even somewhat of pansy around certain dogs and quite friendly with others. He is still that way for the most part with dogs he is familiar with.
That being said, there are a couple of dogs he sees, all of whom would kick his yorky butt from here to kingdom come if the opportunity presented itself. He just goes ballistic. I have tried rolling him over on his side, fingers to the neck, getting him into submissive state, but he is having nothing to do with it.
Wondering if anyone has any thoughts, ideas, or techniques to stop this embarassing display of false bravado?

I am just a little frustrated that he has gone from rolling over and displaying the red rocket to a Yorkie masquerading as a rabid pit bull.
Maybe it was the pigs ear I gave him that accounts for the Jekyll/Hyde transformation
Thanks all,
