Do not eat dog food if it has expired. Because once the shelf life of dog food has passed, it may go rancid and its nutrients will be lost. If the dog eats it, it may cause gastrointestinal discomfort, diarrhea and other symptoms. Therefore, when choosing dog food, you must pay attention to the shelf life of the outer packaging and reasonably calculate the time for your dog to eat dog food. There is no need to store too much dog food at home, causing unnecessary waste.

Methods to judge whether dog food has gone bad:

1. Touch it with your hands. If dog food is stored in a humid environment for a long time, it will easily become crumbled and become soft due to absorbing too much water. You can feel the difference when you pick it up.

2. Smell with your nose. The smell of spoiled dog food will be unpleasant. You can smell the sour or rancid smell of the dog food.

3. See with your eyes. From the surface, you can see that there are signs of mold on the dog food particles, with some green or white mold appearing.
