Back when my dog was "conventionaly treated" for the first 3yrs I had him and before switching to raw - the cow patti poops prevailed...3 yrs. I switched foods several times (costco, nutro, royal canin, nutrience, natural balance - royal canin was more successful, but did nothing for his winter itch) All these brands had been on a recall list at some point during this time too - but that's off the subject - just saying, that's some pretty bad odds
He was also tried on metrondizole, tylan, and panacur...nothing worked.
THe reason - I believe with RC was the hydrolized protiens (which is what enzymes do) that may have helped, but also the bulking agents, which treats the symptom not the cause.
I was pushed into switching kibble to LID re: "chicken allergy" (bull
- not allergic in the summer)...The cow patti poops returned...I was topping up his food w/canned to get him to eat the junk (Merrick's soup for the soul - but ones that had no ingr. he had before), still didn't care for it (must have known it wasn't right for him)....so, the vet said it was fats try script diet (NOPE! wasn't going to feed my dog corn as main ingr. I had been researching and researching all along)...this revisited poop issue with the LID went on for 8 months,as I had to rule out during the "itchy faze time of year"...However in Sept/Oct...there was some slight improvements when I added a plant based enzyme by Solid Gold - still not enough though. Come Jan. 2nd...Went to see holistic vet - said give a pancreatin enzyme as plant based was not enough and switch to raw and low fat. Jan. 4th I gave a 100% Raw meal. NO intro slowly as suggested when making a kibble switch...The very next day he had a perfect brown solid segmented poop!!!! The first one in a year.
Sorry about the overblown...been there done that story.
Readers digest version - treat the cause, not the symptom
Diarrhea - symptom (bulk fillers - no)
Cause - SIBO, fats, enzyme deficiency - probiotic, enzymes...once off enzymes if symtom returns - then to lower fat diet if doesn't clear up, then look into EPI. Treatment for EPI - ENZYMES
Note: Enzymes can be used temporarily - just a few months to get everything back on track
