Just a thought.
I agree with the possible jealousy and protectiveness of you. Noba does the same thing at the park and with other dogs. If I so much as touch another dog in his presence (exception is my boyfriend's dog Sadie), he goes crazy and chases the other dogs down until he gets them. He stops when told. And when it comes to walks, he always makes sure to position himself between me and any other dog that comes our way. Sounds liek you have the same problem I have... now how to break it????
