hi justice
he was very fearful even from the time that he was a puppy. i socialized him extensively -- took him nearly everywhere (street fairs, parks, schools, training classes, pet stores, hardware stores, friends houses etc)....but he still was very timid and fearful of new places/people/situations. he started to become fear aggressive about a year ago...and altho i was able to manage him well enough, it did not improve. he started to get worse as he matured, and he ended up biting me twice on two separate occasions (once on the hand and once in the face). because he was becoming so unpredictable as to what would scare him and what would not, and becoming aggressive to me and my other dog as well, i decided the best thing to do would be to put him down.
