DS: Switching dog foods and an important question?

hopefully you realize that you can't just switch your dog to a new food - you have to gradually introduce the new stuff to him or he will have non stop diarrhea. you should start with putting 1/4 new food in with the old food serve for a day or two then switch to 1/2 for several days and then 3/4 and then switch over. watching how he does with the bathroom situation will help direct you in how long to feed the mix. if he seems to do ok, you may be able to switch over quicker.
