Hi Robert L-
I’m assuming since you are working with a vet, that you have had a fecal test done. Puppies often get internal parasites, such as worms, giardia and/or coccidia. My pups had them all! Some of them can be intermittent and hard to detect with only one test. Have you tried a dewormer like Panacur?
You mention IBD meds, was it metronidazole? Is the poop nasty smelling and greenish or yellow?
Pumpkin never worked for my dogs, but the pectin in no sugar added applesauce and bananas were helpful. Talk to your vet, but Forti Flora and VetriPro BD were supplements that also helped while my dogs’ tummies were healing. It does take a while. I know it’s tough, but be patient. I kept switching foods too. Just making it worse!
I know it’s stressful. I hope it gets better soon. Take care.
