Are you sure you want to remove from your connections?
I adopted Jorge when he was 1.5 years old. I knew something was wrong. The first sign was his sensitivity to noise (I could not watch TV). He also barely had eye contact, had a very short attention span, was one track minded (which could be an advantage too), never relaxed or settled (although with age he has mellowed - expected), and would aggress when sleepy or sleeping (common). When I became a dog trainer I was able to identify precise triggers of aggression.
