I use a narrow web collar on both Jas and Xerxes. It has the quick release catch. I will never ever get a buckle collar for my dogs. My younger brother used to live two doors down from me. He had a fenced in back yard. He had 2 dogs, one was a golden and the other was, they thought, a blue healer shepherd mix. They found him one winter. One day I answered the door where someone was frantically pounding on it. It was my brothers wife screaming for my help. I ran over and saw that the blue healers buckle collar had got caught on the goldens canines and he was slowly choking to death. We frantically tried to cut the collar, pull it free, everything we could think of to no avail. We had to watch that poor animal slowly choke to death. It was horrible. After that, I have only ever got quick release collars. It is a very horrific memory.
