The Dangers of Using Plastic Containers for Dog Kibble Storage

Proper storage of dog kibble is essential to maintain its freshness and nutritional quality. While many pet owners transfer dog food from its original packaging to plastic containers for convenience, it’s important to be aware of the potential dangers associated with this practice. At the Seattle Canine Club, we prioritize the health and well-being of our furry members. In this blog post, we will discuss the risks of using plastic containers for dog kibble storage and why we recommend an alternative approach.

The Problem with Plastic Containers:

Plastic containers may seem like a convenient option for storing dog kibble, but they can pose several risks to your pet’s health. Plastic is not airtight, which means it fails to provide optimal protection against moisture, air, and light exposure. These factors can lead to the degradation of the kibble’s quality, including a loss of essential nutrients and the potential growth of harmful bacteria.

Chemical Leaching:

Plastic containers have the potential to leach harmful chemicals into the stored food. Certain chemicals found in plastics, such as bisphenol A (BPA), phthalates, and polyvinyl chloride (PVC), have been linked to various health issues in humans and animals. These chemicals can migrate from the container into the dog food, posing a risk of ingestion and potential health problems.

Preservation of Freshness:

To ensure the longevity and freshness of dog kibble, it is best to keep it in its original packaging. The original bags are specifically designed to protect the food from moisture, air, and light, helping to preserve its nutritional value. By using the original packaging, you can maintain the quality and freshness of the kibble for a longer period.

Seattle Canine Club’s Recommendation:

At the Seattle Canine Club, we highly recommend using the original kibble containers inside plastic airtight containers for storage. This approach combines the benefits of the original packaging with the additional air protection provided by these plastic containers. These containers serve as a barrier against moisture, pests, and light exposure while keeping the dog food securely sealed.


Proper storage of dog kibble is crucial to maintain its quality and ensure your pet’s health. Using plastic containers for direct storage can introduce potential risks, including nutrient degradation and chemical leaching. At the Seattle Canine Club, we prioritize the well-being of our furry members, which is why we recommend using the original kibble containers inside plastic totes for optimal freshness and safety. By following these guidelines, you can provide your dog with the high-quality nutrition they deserve.
