I have a 2 YO Saint Bernard female that cant eat anything! I have had her on just about every kind of food and she still gets loose stools all the time. I have had her checked for worms and there is none in there. I had her on Panakare plus for a month and no results. She is eating Innvoa dog food now and has been on this for 3 months ..no change.So my Q is does anyone out there have simular issues with their dog and would you have any suggestions for me.
