I think that type of treat is good too. They have a long shelf life, so I don't really consider them the same as fresh raw. While many dogs thrive on fresh raw food, it does have documented risks from pathogens and bone injuries. There is no science that shows evidence that raw is better than cooked/commercial diets. You could cook up some meat as a tasty kibble topper or special treats too!
