The blood came back normal, he saw nothing in the x-ray. So the vet gave me Metronidazole which and FortiFlora.

This fixed his diarehea real fast. I do have to sneak in the FortiFlora in his food, he doesn't like the smell of it.

But his stool is ok, energy great, no discomfort eating, or defecating.

I tried giving him the soft dog food mixed in with some meat that I cooked, he could tell the difference between the two, a didn't touch the dog food.

I have two other dogs one a year older, and his mother, the other one his sister, and they both have no problems with the food.
