How to gradually switch to new pet food.
Changing pet food instantly might cause a stomach upset thus result in loose stools. It is best to introduce the new food gradually so that the pet's body adjusts slowly to the new ingredients. Here is how you can switch to a new food: Start by adding a small amount of your pet’s new food to their current food (Ex 20% new food vs 80% old food). Gradually increase the new food amount and decrease the current food amount at each feeding (Ex 20% increments at every serving). Continue this method for approximately one week. For sensitive pets, extend the period to 10 to 14 days. Also it might be helpful to make sure the last memory that the dog had of the food is that of craving. Try to remove his portion by lifting the food bawl upwards. Starving your dog is never advisable however reducing his portion at first will incentivize your pet to try the new food you want to give her. What your dog remembers last about any experience is what your dog will learn about that experience.
