I had a new young rescue-about 8 mos. old who was fine when I took him out of the crate which was in the car. He was unable to see the leash and I was able to get it on his collar just fine. I took him to the fenced-in backyard, unleashed him, and let him run around with the other rescues. When I went to get him, I was holding the leash and trying to get him to come to me. He was able to see the leash and when I approached him and tried to put the leash on him, he bit my finger. I was unable to get him in the house and had to leave him outside while I did a transport for two rescues. Thankfully, my roommate was home to keep an eye on him. I found out that he had a fear of leashes, along with other things and also socialization problems. It really bothered him if he saw a leash in the air which would be above him. It seemed to be okay if I could put it on below him. I had to work with him for months to have him accept leashes. Sometimes he will still act hesitant about them. From time to time I will have him and the other Bs play with the leashes and make a game out of it. I had to do the same thing with a broom.
I obtained him from an OH Amish breeder/dealer and I can only imagine what the living conditions were like. This man was not the original breeder.
I had his eyes CERF'd and it was not an eye problem. I thought that might be the problem since the leash was coming from above.
