When they say dogs food is new and improved who tastes it?

When dog food brands advertise their products as "new and improved," they typically conduct taste tests with trained panels of dogs rather than humans. These tests help assess the palatability and appeal of the food to canine consumers. Additionally, pet owners may also provide feedback based on their dogs' reactions, but the actual tasting is done by the dogs themselves. This approach ensures that the food meets the preferences and nutritional needs of dogs.
