What is the recommended duration for gradually introducing new food when transitioning a White German Shepherd?

Seven to ten days

Changing a dog's diet abruptly, especially one with a sensitive digestive system like many German Shepherds, can easily disrupt the gut microbiome, leading to adverse reactions such as diarrhea or vomiting. To prevent this digestive upset, a gradual transition period is strongly advised. The standard protocol involves mixing increasing proportions of the new food with decreasing amounts of the old food over a period spanning seven to ten days. Furthermore, during this changeover, owners must monitor the daily stool quality; if the transition rate causes stools to become too loose or firm up too rapidly, the process should be intentionally slowed down, prioritizing digestive stability over the manufacturer's suggested timeline.
