Once you open a bag of dog food, its freshness is exposed to the elements. The three factors that affect the nutritional value and quality of dog food after it is opened are air, moisture and high temperature. To help combat these forces, here are some tips for dry dog ​​food storage.

From The oil from kibble tends to make the container greasy, and you can then contaminate fresh food with rancid oil from an old bag."

Moisture can cause mold, which can make your pet sick. High temperatures can also speed up the degradation process and cause nutrients in food to break down. You will want to avoid storing dry dog ​​food in places where temperatures exceed 100 degrees Fahrenheit, such as a garage or shed.

Once opened, you have 24 hours to store the food if your dog does not finish a meal.

Seal and refrigerate to maintain freshness

"Once opened, we like to wrap the open end of the tube in foil and secure with a rubber band," she says. "This will last up to a week in the refrigerator. ”

Tips for freezing dog food

If you have more food than your pet can eat before it goes bad, you can always use your freezer. It can be frozen, to prevent it from going bad. You can also transfer leftover canned food to freezer-safe bags or containers before freezing.

Make sure you are buying the correct amount of food

Dr. recommends pet owners see their veterinarian to find out how much food their pet really needs. "With 59 percent of cats and 54 percent of dogs in the United States being overweight, we noticed that pet owners don't actually know how much to feed their pets," Dr. Nelson said. "You can't always follow the chart on the bag because your Pets may need more or less food, depending on their condition, age and activity level. It's important to know how much food they really need. Then, buy bags of food that they can actually eat within three to four weeks, or buy portions if you're willing to buy in bulk. "
