Immune-mediated hemolytic anemia (IMHA) is a serious and potentially fatal disease that can occur in both dogs and cats. The disease often has an acute onset, making rapid recognition and timely treatment essential for a successful outcome.
The diagnosis and treatment of IMHA can, however, be very challenging. No single diagnostic test is completely reliable, and some patients do not respond as expected to standard therapy. IMHA also presents differently in dogs and cats. In general, the prognosis is poorer in dogs, where severe complications such as thromboembolism and SIRS (systemic inflammatory response syndrome) are seen more frequently than in cats.
In this short, focused webinar, we first review the physiology, diagnosis, and treatment of IMHA. We provide practical tools to help you reach a correct diagnosis, and we discuss how to approach persistent or difficult-to-treat cases in clinical practice.
The webinar also covers the important differences between dogs and cats, as well as the recently published ACVIM consensus guidelines on the diagnosis and treatment of IMHA in both species.

Geert Paes, DVM, Dip ECVIM-ca After graduating as a veterinarian in 2006 from the University of Ghent, Geert completed an internship and residency in small animal internal medicine. She remained at the university until 2012, after which she moved to Western Canada. There, she spent several years working in first-line practice, before transitioning back into emergency and referral medicine. This experience gave her a deep understanding of the realities of clinical practice and a strong appreciation for the challenges faced by general practitioners on a daily basis.
Geert has been a Diplomate of the European College of Veterinary Internal Medicine (ECVIM-CA) since 2017 and is (co-)author of several scientific publications. She currently works as a specialist at Boundary Bay Veterinary Specialty Hospital in Surrey, Canada, and as a teleconsultant.
However, what truly sets Geert apart is her passion for teaching. She is known for her ability to explain complex topics in a clear, accessible, and practical way, making internal medicine understandable for every veterinarian—regardless of their level of experience. Her teaching style is characterized by clear explanations, additional context, and a strong focus on clinical reasoning.
Having worked in first-line practice herself, Geert strongly believes that the “ideal scenario” is not always achievable. Her goal is not only to teach what the gold standard (Plan A) looks like, but also to equip veterinarians with the tools and confidence to make well-reasoned decisions when they need to rely on Plan B or Plan C.
Her courses are highly valued for their practical approach and direct applicability in daily practice, and her enthusiasm for internal medicine is contagious—she consistently succeeds in inspiring others to develop the same passion.
Driven by this vision, Geert founded OnlineVetTraining (OVT) in 2019, with the aim of providing accessible, high-quality, and clinically relevant education for veterinarians and veterinary professionals worldwide.
