What We Don’t Like About IAMS Dog Food

Unnamed Animal Ingredients

Although IAMS identifies the main ingredients, there are still other animal ingredients whose sources are unidentified.

Unidentified animal ingredients are another sign of poor quality. Several recipes call for fish oil, which can be prepared from any kind of fish. Unnamed animal components are frequently a low-cost, low-quality ingredient derived from rendered waste of numerous proteins.


Colors, such as iron oxide, caramel, and titanium dioxide, are pigments that are added to foods to make them more appealing to consumers. They are often used to conceal the grey color of rendered substances and have been connected to health problems.


If you’re looking for affordable, high-quality dog food that has been thoroughly tested for food quality and safety, this is a brand to look into! IAMS dog food demonstrates that it is a reputable dog food firm that has been making animal food for over 50 years.

While some of their ingredient choices are questionable, their meal is still an excellent alternative, especially for those on a budget.
