Best of luck at the vet, I hope they have some answers for you.

From what I read about the malabsorption issues is that it could be several different types and that it is probably not curable, only maybe manageable. I have not heard of many bulldogs with this problem , it is usually other breeds.

If a dog can’t digest its food, then they cannot get any nutritional value from it and it goes right thru them. Even with enzymes or probiotics added, it is not a cure. Not a very good future for this dog if that is what is wrong…
