Are there any smarter dogs that are well trained by working dogs and don't bite? Dogs are not ugly. They only bite when they bite.

At present, there are about 400 kinds of purebred famous dogs in the world, among which 100 kinds of famous dogs are loved and recognized by people. China has also cultivated more than ten kinds of famous dogs, such as Beijing Dog, Pug Dog (Axe Dog), Song Shiquan, Tibetan Yellow Dog, Lassa Dog, Shih Tzu Dog (China poodle), chinese crested, Tibetan Mastiff, Sha Pigou and Tibetan Mastiff.
