agreed, there are a lot of vets who listen to your concerns, and will prescribe based on your knowledge of the dogs symptoms first rather than what can be a false negative fecal. change to a vet who listens to your concerns and who you feel comfortable with. Antibiotics don’t have to be the first option unless there is a life-threatening infection, many dogs can get over an over abundance of bad bacteria with change of diet and lots of probiotics and mastic gum is also used to heal the intestinal tract too. because my shitzu had severe inflammatory bowel disease that is what a holistic vet had to prescribe (mastic gum) along with raw diet, probiotics. i found the mastic gum a savior for my Banjo because he was lethargic and very ill too but wouldn’t use it for a dog who is acting normal other than the diarrhea. Don’t let the diarrhea go on for long as was said by others he will get sicker and sicker because he will become dehydrated and not absorbing enough nutrients, therefore you might consider changing the brand of the slippery elm or increasing the dosage to firm up that stool soon.
