My dog's diarrhea worsened on meds. Can I give Loperamide or Flagyl?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed | Male | unneutered | 1 year and 11 months old | 25 lbs

My dog was having diarrhoea ( not watery but semisolid pooh ) for 2 weeks on and off . He eats well and active. I was concerned about the frequency of pooh , sometimes 10 times / day than consistency . Vet said it may be colitis and started on sulfazalazine . He is on that for 2 days , but since started that he is worse & having watery diarrhoea about 10 times / day I'm not happy with that treatment. He is active and happy and eating well . Should I give him Loperamide or Flagyl plz

It would be best to consult with your veterinarian before changing treatment or giving other medications. Legally, we are prohibited from recommending medications or dosing information in the absence of a physical exam and a patient-veterinarian-client relationship. You can try withholding food for 24 hours. Allow small amounts of water or an unflavored electrolyte replacement beverage. Resume feeding a bland diet in small frequent amounts until symptoms resolve. Transition slowly to the regular diet afterwards. A stool sample should be submitted to diagnose intestinal parasites or bacterial overgrowth. A veterinary probiotic such as Prostora, FortiFlora or ProViable may promote gut health.
