Dr. Marcus Keller is a veterinarian whose day-to-day clinical work is in emergency and critical care, with a professional focus on toxicology — the medicine of accidental ingestion, poisoning, and acute exposure. Over the course of his career he has managed thousands of emergency presentations ranging from chocolate and xylitol ingestion to anticoagulant rodenticide exposure, and he brings that frontline perspective to PetsCareWiki's review of our most safety-critical content.
Doctor of Veterinary Medicine (DVM), with advanced training and board-level specialty credentialing in emergency and critical care. Ongoing continuing education in veterinary toxicology through the ASPCA Animal Poison Control Center professional program and AVMA.
Dr. Keller's role is to catch the kind of errors that matter most: a miscalculated toxicity threshold, an outdated dosage, a missing red-flag symptom that should prompt a reader to stop reading and call their veterinarian. His sign-off is required on every toxicity, poisoning, and emergency article before publication, and on major updates to existing ones.
