My bulldog in the past 6-8 months is showing agression towards people. He doesn't do it very often so its difficult to figure out what the trigger is. I had a friend come over and he went directly after her, he was definately going to bite her. This happened last year. He also has done this towards my mother, one minute he was fine with her and the next he was going to attack her (that happened a few months ago). Today he tried to attack the vet technician and she already had greeted him in the beginning of the visit and he was fine and when she came back into the room he was in the attack mode. I noticed that he gets this strange look on his face like he's not sure of something with that person.
Ollie has been a wonderful family dog! We love him very much, but because of this aggression, I am thinking about giving him up to someone that might be able to handle him better.
My fear is that he might hurt someone because he is unpredictable at this point. We have family and friends in our house all the time. 98% of the time he is fine, but I'm really concerned about the 2%. I don't want to take a chance and someone gets hurt.
Ollie is 2 1/2 years old. No medical issues. We started socializing him when he was a pup. We have done dog obedience etc.

Any suggestions?
Thanks
