The origin of the Teacup Dog:

The Teacup Dog originated in the United States and developed in Japan and South Korea. The first teacup dog was caused by a genetic mutation. Its small size was loved by many people. When people discovered the hidden business opportunities, they began to use artificial and technological means to breed a large number of such deformed dogs. It took half a century of breeding and improvement for teacup dogs to become the current pet teacup dogs.

Why it is not recommended to raise teacup dogs:

1. In order to keep teacup dogs in a compact state, teacup dogs will be forced to undergo surgery. The emergence of teacup dogs is not the result of natural selection, but due to congenital deficiencies.

2. The life span of teacup dogs will be shorter than other breeds of dogs, and their bodies will be relatively weak, which will be more troublesome to raise. Therefore, it is recommended that parents with no breeding experience not to buy them, and there are many teacup dogs on the market now. They are not pure, and the risk of purchasing is relatively high.
