Changing Your dogs Diet Cont: then make it 75%-25% new food for three to four days and finally 100% new food. But what kind of healthy dog food diet does your dog need? That depends on your dog. Like people, dogs have individual tastes. Some dogs prefer beef, others prefer chicken, lamb or a combination of meats. The best way to find out what your dog likes, is to experiment with different kinds.The most important thing to remember when selecting a healthy dog food to replace your dog's current diet is to choose a high quality, low grain from a company who manufacturers there own food so they know the source of every ingredient. Foods produced by bulk manufacturers have been involved in a number of pet deaths because of poor ingredient control. An diet is very important but knowing what not to feed your dog is equally important. Sherry Woodard, dog trainer and care consultant. www.critterschoice.com
