Dog food on the market is divided into domestic dog food and imported dog food according to the origin. The quality is uneven and it is difficult to choose. My suggestion is to look at it before deciding to buy it.
Fake brands import a lot of dog food. You can check the import feed registration information of the Ministry of Agriculture. As long as it is a regular imported dog food, you need to have an imported feed registration certificate. For example, the Champions League dog food that my dog is eating now, check it here. Also, the customs quarantine certificate.
There are many brands of domestic dog food, many of which like to have English names. It is suggested to check the quality inspection report first, which can be found on the website of the State Commodity Inspection Bureau, and compare the information inside, such as origin, batch number, nutritional composition and so on. Many brands are scribbled, and some are just ordinary feed, which is a kind of hype. You'd better check the hygiene license, production license and so on.
