Video: Blister Beetle Toxicity in Horses

In this excerpt from the September 2019 episode of Ask the Vet, Dr. Gray and SmartPaker Dan answer a viewer question about blister beetles in alfalfa cubes and hay, in general. The two discuss blister beetles and where they’re found (you might be surprised), when they are most commonly found, what you can (and should) be doing to make sure your hay isn’t contaminated, signs that your horse might have eaten contaminated hay, and why they’re called blister beetles in the first place.
