23. Chinese Shar-Pei
Shar-Pei translates as “Sand Skin”. They have a reputation of being one of the best medium-sized watch dogs due to their strength and independence. A drawback is that they can be too independent at times. This aloofness can lead to aggression towards other people and their dogs. Early training as puppies (for early socialization purposes) will keep these too-smart-for-their-own-good dogs from acting out and disobeying.
