Wet dog food, especially the canned variety, is a palatable and hydrating option for our canine companions. However, unlike dry kibble, wet food is more susceptible to spoilage. So, Can Canned Dog Food Go Bad? Absolutely. Knowing how to identify spoiled food and properly store it is essential for maintaining your dog’s health and well-being. This guide will help you recognize the signs of spoilage and ensure your furry friend enjoys safe and nutritious meals.
7 Signs Your Canned Dog Food Has Gone Bad
1. Examine the Expiration Date
The “best by” or “use by” date stamped on the can is your first line of defense. While not a definitive indicator of spoilage, it represents the manufacturer’s guarantee of quality and nutritional value.
What to Do: Always check the date before opening a can. While the food might still be safe shortly after the date, its quality will degrade over time. Practice FIFO (First In, First Out) – use the oldest cans first.
2. Inspect the Can for Damage
Canned food relies on a hermetic seal to prevent bacterial contamination. Dents, rust, or bulging can compromise this seal, leading to spoilage.
What to Do: Before opening, carefully examine the can. Avoid cans with any signs of damage, as the food inside may be contaminated. Even a small dent can be a point of entry for bacteria.
3. Watch Out for Swelling or Bulging
A bulging can is a significant red flag, indicating the presence of gas-producing bacteria. This bacteria can cause serious illness in your dog.
What to Do: Discard any can that appears swollen or bulging, even if the expiration date is still valid. Do not open it, as it may release harmful gases.
4. Observe Discoloration or Mold
Visible discoloration or the presence of mold are clear indicators that the food is unsafe for consumption. Mold can appear as white or grey fuzz.
What to Do: If you see any signs of discoloration or mold, discard the entire can. Do not attempt to salvage any portion of the food.
5. Trust Your Nose
Smell is a powerful indicator of spoilage. Fresh canned dog food has a distinct, meaty odor. A rancid, sour, or otherwise “off” smell indicates bacterial growth.
What to Do: If the food smells unpleasant or different from its usual odor, do not feed it to your dog. Err on the side of caution. Spoiled dog food can also have a chemical or paint-like smell.
6. Check the Texture
The texture of spoiled canned dog food often changes. It may become slimy, sticky, or excessively watery. These changes are due to bacterial activity breaking down the food.
What to Do: If the texture seems unusual, discard the food. A healthy, appealing texture is key.
7. Look for Pests
While less common in canned food, pests like bugs can sometimes infest compromised cans, especially those stored improperly.
What to Do: If you find any bugs, discard the food immediately. Inspect your storage area and consider moving the remaining cans to a more secure location.
Proper Storage of Canned Dog Food
Proper storage significantly extends the shelf life and safety of canned dog food.
- Unopened Cans: Store unopened cans in a cool, dry place away from direct sunlight and extreme temperatures.
- Opened Cans: Once opened, transfer the contents to an airtight container and refrigerate immediately. Opened canned dog food typically lasts for 2-3 days in the refrigerator.
