After further investigation and understanding, we learned that the puppy that Ms. Cai bought online was actually traded through another pet store. The pet store claimed that they bought the puppy from the original merchant and had obtained the consent of the original merchant. However, when Ms. Cai received the puppy, she discovered that the lines around the puppy's eyes, the traces of the ears being cut, and other unusual behaviors all took place during the transaction.

Ms Tsai believes that the original seller did not disclose this information to her, but only informed her of the problems after the transaction was completed. She was therefore very disappointed and angry because she thought she was buying a healthy and cute puppy, but found out that she had been deceived.

Ms. Cai also mentioned that during her communication with the original merchant, the other party has always denied that there is any problem, and tried to convince her to accept the puppy, and even asked her not to hold them accountable. This behavior has strengthened Ms. Cai's belief that the original merchant deliberately concealed the truth in order to increase her sales and induced consumers to make wrong choices.

The original merchant also responded to the incident, saying they would refund Ms. Cai's purchase fee for the puppy and publicly apologize. However, they also said they would continue to work hard to improve the service and ensure that similar things would not happen again.

Overall, this incident has shown us the lack of integrity in online shopping, and it also reminds us that we must carefully check the quality and authenticity of the goods when purchasing goods to avoid unnecessary losses. At the same time, we should also call on e-commerce platforms to strengthen supervision of merchants and protect the rights and interests of consumers.
