What should I do if buying a dog online does not match the real thing?

If the dog you bought online doesn't match the real thing, you can consider the following methods:

1. Directly ask the merchant to return the goods: keep the evidence and directly ask the merchant to return the goods.

2. Complain about the merchant to the e-commerce platform: If the merchant refuses to return the goods, you can complain about the merchant to the e-commerce platform.

3. Complain to the consumer association: If the e-commerce platform can't solve the problem, you can complain to the consumer association.

4. Bring a lawsuit to the relevant people's court: If the above methods fail to solve the problem, you can bring a lawsuit to the relevant people's court.

In addition, if you buy pets online, you can also find the seller in the following ways:

1. Find the seller through platforms such as Taobao or idle fish.

2. If you don't keep the transaction records, you can find the seller through payment platforms such as Alipay or WeChat.

If you still can't find a seller, you can seek the help of a pet rescue organization.

I hope the above information can help you solve the problem.
