In this episode, host Alyssa Watson, DVM, talks with Britt Thevelein, DVM, DACVECC, about her recent Clinician’s Brief article, “Therapy Protocols for Acute Hemorrhagic Diarrhea Syndrome in a Dog.” Dr. Thevelein covers typical presentations, expected hematologic changes, and why calling it “HGE” is a thing of the past. She also emphasizes that fluid therapy is the most important aspect of treatment and explains why metronidazole can be considered almost entirely unnecessary.

Key Takeaways

  • Acute hemorrhagic diarrhea syndrome has replaced the term “hemorrhagic gastroenteritis” (HGE) because evidence has shown a lack of gastritis lesions.
  • Clostridial toxins are suspected as the cause of AHDS.
  • Dogs with AHDS will have high-normal to elevated PCVs but normal to low total protein.
  • Aggressive fluid therapy is the mainstay of treatment.
  • Antibiotics are NOT routinely necessary; when used, they should be broad-spectrum to address the risk of sepsis from bacterial translocation.
