Hi, could be IBD (Colitis) she may have a food intolerance/sensitivity, my boy was pooing blood & mucus, mucus & blood is from something irritating the bowel (Colitis). My boy cant eat boiled rice or boiled oats in cooked meals or wet tin foods, boiled rice & oats irritate his bowel causing blood, mucus poos…he also cant have any gluten & most vet diet have gluten, corn & boiled rice, so he cant eat most vet diets plus vet diets use chicken or hydrolyzed chicken….so if your dog has a sensitivity to chicken then vet diets won’t help…..
Have you tried to feed a cooked limited ingredient meals, just 1 protein & 1 carb, a protein she hasn’t eaten before, a protein low in fat is best & try adding some boiled potatoes, or sweet potatoes if you want more fiber… My boy does real well on beef, pork, lamb or fish, I have found….Elimination diets are best to feed when this is happening, then when she is stable (firm poos) then only add 1 new ingredient each week…… in the beginning less is best cause you will not know what is causing the diarrhea, if she is eating too many things or too many supplements are given… & keep a diary…I’ve been cooking this morning, to lightly boil some meat & boil some sweet potatoes doesn’t take long, I make 1/2 cup size meals. I put thru the blender it helps with digestion if you dogs gulps food, then I freeze small meals..
You may need a new vet, a vet that knows more about IBD…..
