Sadly had to be done.
I remember our neighbor owned a chow where we lived before the house we purchased.
I was washing our truck out front and a neighbor had one. Usually they kept it on the leash. That day the owner was out front and the dog was off the leash. His dog came around the side of the truck just in he same way as the one in the video.
I grabbed Hershee and told the guy to get his dog put it on a leash. I promised I would never let Hershee out front without one if he made the same promise. I also told him that if the dog is lose out front I would kill it.
I had a friend when I was young who was mauled by a chow. Chows were bred to be fighting dogs by the Japanese. They are some of the top fighting dogs you can find. A vicious bread that has no soul. Any dog that can kill a pit bull in a dog fight is not something I want around children.
The problem is a pit dog looks mean, but a chow looks harmless to kids. The cuteness gives a false sense of security. in my book that makes them worse than a pit bull.
Not only that, pit bulls have to be trained to be deadly, chows are the only dog I know of that does not have to be trained, other than maybe a rottweiler. I would never own either. I would get a pit bull before ever getting a chow, or rottweiler.
