Today i took my 11 month old GSD for a long walk to my local cigar shop. Along the way I saw quite a few people that I knew, and had no issues with Ty barking. I arrive at the cigar shop, and a dog in a parked car is going NUTS, ty didnt bark back, but he was definatly watching that dog. We go inside, and a little maltese runs up barking at him and this is when he started barking. He wouldn't let anyone get near him without barking at them. I seem to think I have done a decent jod socializing him, but obviously not enough, and since he barks at some people, it is difficult to have them come up to him and be properly introduced because now they are afraid of him. BTW, he has never bitten anyone, just barks.
Where should I start?
