Question by Diana Williams: Is it normal for a puppy to have diarrhea after changing their food?
I recently switched my 5 mth old shih tzu from science diet to wellness and was instantly hit with that dreaded puppy diarrhea! Is this the new food and how long will this last?
Answer by darlene r
probably the food. when changing a dogs food, you have to first mix in a little of the new food with the old, and then gradually increase over a couple weeks..feed your dog small amts of the old for three days, then mix in a little of the new and see how it goes.
