Bruno is a four year old German Shepherd. We gave him training took classes but he never really got socialized to other people or dogs. He has bitten me twice both times sort of a rebound from external forces. We fear every day there will be a bad accident. We moved to Maine when he was young and are in a very rural secluded area so he sees less people than ever. Although we put him in the car and take him to town every day for a walk so he sees people he has not seen many up close. We also work hard at exercising him all day.Now we are moving back to NY and don't know how to fix this mess. His behavior seems based on fear and he is over the top with guarding behavior which we cannot seem to shut down. He is nervous in the car constantly whining and stressing us out. I am to the point I feel we should find a working job for him with the police force or something because he is smart and we don't know how to handle him. Unfortunately my husband refuses to give him up and the problem just continues. I feel this is a ticking time bomb as long as it is not addressed. Help!!
