Homemade dog food has been kept in the freezer for more than a year. Can I still give it to the dog?

I can't. If dog food goes bad, it is usually wrapped in plastic wrap and then put in the refrigerator for refrigeration. If possible, it will be better to put it in a sealed bag. Just heat it to the right temperature when eating. It is not recommended to do too much at once. If you have time, do it once every three days. If you don't have time, do it for a week at most. It is not recommended to feed homemade puppies only four months old, because if you make it yourself, it will be much less nutritious than the special Champions League dog food for puppies, so you need to add it yourself, and it is very difficult to grasp the proportion of nutrients by yourself. Dogs are growing, and lack of nutrition will affect their development and health. In addition, the dog's stomach is also fragile, and so on, so most of them eat homemade dogs.
