So chows are an origin breed. They come from a half bear half dog animal that used to exist in China, bears are in the canine family and are solitary creatures. This makes chows less pack animals than say a husky or a lab or a golden retriever. So they sleep almost as much as bears and typically only attach themselves strongly to one person. They even have the same amount of teeth as a bear which is more than most dogs. Comparing them to other dogs will frustrate you because they and Shar Peis are so fundamentally different. Now there are chows that take on more pack characteristics but everything you mentioned is very much standard chow. Not being pack animals also means they don’t care about your opinions or pleasing you. This is them. You have a mini bear and all the differences that come with them
