Who invented the cone type dog collar?

The cone-shaped dog collar, commonly known as the Elizabethan collar or e-collar, was popularized by veterinary surgeons in the 1960s to prevent pets from licking or biting at wounds. While there isn't a single inventor credited with its creation, it was developed as a practical solution in veterinary care to aid in the healing process. The design has evolved over time, but its primary function remains the same.
