Hi Jean,
Just like everything else,not all things out there meant for our use works the same for each person or animal. Myself I use and would not stop using the probiotic brand I found for my Joey. He has been on Dr. Merrick's complete probiotics for years because of his health problem. As far as there being probiotics in some dog food I have read that it may not be all that good that way. This is something I would suggest your reading up on to see what information there is on the pros and cons of it's use put in to dog food and then you can make an informed decision on what you learned. You could even do that regarding how good it is to use probiotics on there own. Hope you make the best choice for you.
