I am new to the forums and I am hoping you all can help me out. My chocolate lab puppy is almost 18 weeks old now. The food we have him on know is the ProPLan forcus puppy. I was hoping to keep him on the same food as our other dog for convenience but unfortunately he keeps having diarrhea. He has been to his vet to rule out any internal issues (Tried various medications) so it has been narrowed down to the food. Anyone have any recommendations? The food choices are overwhelming. I brought home a bag of Taste of the wild puppy yesterday and got in trouble for it being grain free as my wife is a vet tech for the veterinarian we take our animals to and the FDA report has stirred up a lot of concerns.
