I recently rescued a male tri color from a breeder that was neglecting him. He is 2 now and I got him when he was 1.5 year old. He has never gotten the socialization he needs. He is very passive and scared of everything. Luckily, he is very good with my kids and my other dogs. When I first got him, he is very scared of me, but now starting to trust me. When I walk him, he is scared of the outside, and cars...When people bend down and try to pet him he backs up, like they are going to hit him. This makes me really sad. How can I get him socialize at this age? And not be scared of anything? Espicially of new people? I am giving up on him... I love him dearly....But, I need help.
