What systematic technique is generally recommended over constant food swapping to re-establish the value of the primary food source?

Answer

Implementing a strict feeding time limit, such as removing the bowl after fifteen minutes

A systematic approach involves presenting the meal for a set duration, and if the dog chooses not to eat within that window, the food is removed until the next scheduled feeding time, teaching schedule adherence.
