The Real Reason Dogs Kick When You Scratch Them

The video explores the scratch reflex in dogs, an unconscious reaction similar to the knee-jerk reflex. This reflex is triggered by light touches and may have evolved as a defense against parasites. It involves nerve cells in the spinal cord, bypassing the brain. The reflex is not unique to dogs; cats, frogs, and turtles exhibit similar responses. Veterinarians use this reflex to help diagnose conditions like scabies and mange. Understanding this reflex provides insights into animal health and evolutionary biology.
