Some signs that dog food has gone bad include:
- An unpleasant odor
- A change in color or texture
- The presence of mold or bacteria
- If your dog refuses to eat it
If you're not sure whether or not dog food has gone bad, it's best to err on the side of caution and throw it out. Feeding your dog spoiled food can make them sick.
To prevent dog food from going bad, store it in a cool, dry place and keep it sealed tightly. Once you open a bag of dog food, it's best to use it within a few weeks. If you don't think you'll be able to use all of the food within that time frame, you can store it in the refrigerator or freezer.
