Veterinary Industry Summary: November 5–11, 2023

November 5–11, 2023


Although the potentially deadly heartworm disease can be prevented in dogs, the use of heartworm preventatives may be down.

A recent article published in Frontiers in Veterinary Science revealed that only 39.5% of dogs participating in the Golden Retriever Lifetime Study were receiving heartworm preventatives.

Led by Dr. Lauren Wisnieski, associate professor of public health and research at Lincoln Memorial University, the study identified factors affecting a dog’s likelihood of receiving heartworm prevention. Dogs who were in the highest quartile of height, were sexually intact, or were receiving supplements were less likely to receive heartworm preventatives, while dogs who received vaccines and those who were diagnosed with an infectious disease or an ear, nose, or throat condition during a recent veterinary visit were more likely to receive heartworm preventative medications.

Vetsource data indicates that, on average, parasiticide-purchasing patients are down 5% year-over-year per practice, and year-over-year months of heartworm protection dispensed continues to fall.

Dr. Wisnieski and her team plan to expand their research to include more dog breeds, and explore how the cost of preventatives impacts their use and how the human-animal bond affects preventative care.
