Urgent: Looking for Sucralfate or Metronidazole for My Sick Dog

Hey everyone, I live in the Vanier area and I’m urgently looking for Sucralfate (Carafate) or Metronidazole for my dog. He has a long history of digestive issues and recently started having bloody diarrhea and vomiting with blood, and my vet prescribed these in the past for similar episodes. Unfortunately, I can’t get an appointment until Monday, and I’m trying to help him feel better in the meantime. If anyone has leftover Sucralfate or Metronidazole from their pet (or knows where I might be able to get it quickly, even from a vet or pharmacy without a full visit), please let me know! I’d really appreciate any leads, advice, or recommendations. My dog is 10 years old, a little chihuahua, and I just want to make sure he’s okay. Thank you in advance!
