Yes, my yorkie has IBD (causing major food intolerance), SIBO, a mild liver problem, acute bouts of pancreatits, and (although she may be over it by now) soe type of esophagitis. Then she has true food allergies (extreme itching) and chronic yeasty ears related to that.

Metronidazole worked - for a couple weeks.
Tylan did nothing.
Science Diet Z/D did not work for her.
It was on and off with homecooked foods. The supplement seemed to irritate her though. She also couldn't keep weight on.
Digestive enzymes (the real porcine pancreas type, not plant based' seemed to have some positive effect. I had to put the powder in capsules though or it would irritate her esophagus and she would spit up.

She has been on Purina HA for 1 1/2 years and has done very well.
No pancreatitis.
Not gray, liquid poop.
No major flare ups.
This was after me thinking we could lose her if she continued the way she was.

It isn't perfect. She has mild itchies (treated with steroids as needed), some stool consistency issues (sweet potato is added when there is a problem), and yeasty ears (treated with zymox as needed). However, I am very happy with where we are at. She does not take any drugs for these issues regularly. If she gets into something she shouldn't, I make a decision on whether to induce vomiting. That is sometimes followed by Reglan.

It is a matter of trial and error and it is a long, miserable process.
It is never a bad idea to talkto a veterinary nutritionist in cases like this.

Not all vets offer food allergy testing because it is onsidered unreliable.
