The Piggie and the Shar-Pei are both unique dog breeds, and each has some significant advantages and disadvantages.

The advantages of the Hapi Dog are mainly reflected in its character. They are usually docile, obedient, easy to train, and have particularly good memories. In addition, the pug's hair is short, soft, nice to the touch, and comes in a variety of different colors. However, pugs also have some disadvantages. When they exercise too much, they may become hypoxic, so attention needs to be paid to controlling the intensity of their exercise.

Shar-Pei is a dog breed with a kingly demeanor. They eat relatively small amounts of food, are loyal to their owners, and are wary of strangers, making them good watchdogs. The Shar-Pei's hair is short and hard, and feels rough to the touch, resembling sandpaper for polishing, hence its name. In addition, Shar-Pei dogs are smart and quick-witted, have strong learning ability, and can easily understand and carry out their owner's instructions and training. However, the Shar-Pei also has some disadvantages. For example, their nasal passages are short and prone to lack of oxygen; their skin has many wrinkles, which can easily hide dirt and breed bacteria; and they are somewhat aggressive and may show aggressive behavior towards strangers. In addition, the Shar-Pei's reaction speed may not be as fast as that of some hunting dogs, requiring the owner's patience and specific training methods to stimulate its learning potential.
