Hi all. I have a black lab named Ernie who will be 4 in May. He is very sweet and has a great temperament. When we first got him he was wonderful with all children. A little over a year ago we had a birthday party at our house and we caught 2 children hitting and pinching him. Since then he has been very nervous around all children. He will still gently take treats from their hands, but then runs away. If a child approaches him he tucks his tail and runs away to hide. Sometimes he even cowers like he thinks he is going to get hit. I feel terrible that he feels this way. Is there any way we can help him get over this fear that not all children will do the same thing?
