Differences between fresh and frozen
Fresh dog food diets are ready to be served right away, unlike frozen diets
which can last for extended periods of time. Freezing can preserve a variety of
nutrients, but even when frozen, there are some unhealthy changes that may
happen to the food, including freezer burn, changes in ingredients that affect
how your dog receives the diet, and changes to healthy fats. The changes are
slow, but oxidization over time takes a toll.
The approach of a fresh dog food diet is that we're feeding the nutrients
and ingredients right away to give optimal concentrations, rather than storing
them for extended amounts of time as unknown changes occur within the food.
Your dogs will be the judge and jury though - you can certainly expect them to
be more enticed with fresh food in terms of flavor alone, though you will know
the true nutritional value!
