Well I was more so responding to the biting out of fear comments. I have a dog that is afraid of clippers, but he is a long haired dog and I live in TX, yesterday we had a heat index of 105. I cannot leave his hair long, even though he is an indoor dog, he obviously has to go outside. Should he bite me because he is afraid while I'm clipping him?
I rescued him when he was around 2 years old, he had lived feral his whole life before I picked him up. The first time I put a collar on him he refused to move for 2 hrs, the first time I put a leash on him he refused to walk, when he did he crawled everywhere as long as he had a leash on (which went on for a few weeks). He was scared to walk through doorways, he was scared of human touch. He never once offered to bite, and you can bet he was plenty fearful of pretty much everything. Fear is not an excuse for a dog biting.
