Hi Angel,
What formula’s have you tried? have you tried a dry kibble that is just Lamb meal & Rice?? a kibble with grains she might have been fed a cheaper dry food bought from supermarket or she might have been feed a raw or cooked diet??
My rescue was the same he had to be put on Metronidazole 21days & a vet diet for 9 months to get his gut healthy again…
Have you tried adding a probiotic or kefir to her diet??
Look for a new limited ingredient kibble that is chicken free, there could be 1 or 2 ingredients in the kibble she has been eating that she is sensitive too??…
“Artemis OSO Pure” is simliar to Zignature, my boy doesnt do well on a heavy Legume diet,
It’s best to find a pet shop close by & try pet foods from the Pet Shop so they can be taken back if she gets diarrhea or wont eat it, most pet foods have a palability guarantee money back..
If you live near a Tractor Supply store look at “4Health” formula’s or “4 Health Special Care” Sensitive Stomach formula, the fiber is 3% but it mighten have anything to do with fiber %, it might be an ingredient she is sensitive too….

Keep a diary & start writing down ingredient list & fiber % etc
