If you notice any of these signs, it’s best to err on the side of caution and throw the food away.

Benefits of Feeding Your Dog Fresh Food

While dry dog food can be a convenient option, there are many benefits to feeding your dog fresh food. Here are a few:

Better nutrition: Fresh, whole foods provide more nutrients than heavily processed food.

Better digestion: Fresh food is easier for your dog to digest, which can reduce the risk of digestive issues.

Healthier coat and skin: The nutrients in fresh food can help improve your dog’s coat and skin health.

While it may require a bit more effort, feeding your dog fresh food can have many benefits for their overall health and well-being.

Another option to consider is wet dog food. Here are some pros and cons of each:

Dry Dog Food:

– Convenient and easy to store

Wet Dog Food:

– Higher moisture content can help keep your dog hydrated

Ultimately, the choice between dry and wet dog food will depend on your dog’s individual needs and preferences.
