When it comes to switching pet foods, gradual, proportionate change over time is fine for cats but dogs are different. Most dogs will happily gobble down anything, new food, old food, ancient food or anything that winds up in their bowl. This appetite doesn’t mean that the sudden diet change is not a shock to the dog’s system. Indigestion, diarrhea and worse can result from abrupt changes in his diet. If your veterinarian has advised you to change your dog’s food, do it gradually.  He might recommend a ratio of feeding  50/50 old and new food at first.  Then 1/3 old and 2/3 new food for awhile.  This method will probably agree with your dogs digestive system.

Remember, your pets count!
