Difference Between Horse Joint and IV or IM Injections

In this excerpt from the January 2019 episode of Ask the Vet, SmartPaker Dan and Dr. Andy Kaneps explain the differences between joint injections given directly into the muscle (intramuscular) or vein (intravenous) and injections given directly into the joint. Dr. Kaneps reveals that even though he was skeptical of IV and IM injections initially, there is research showing the efficacy of those injections. He and Dan even discuss one reason why you would opt for one instead of the other.
