Which method is a permanent form of animal identification?

• A. Fur dye.
• B. Shaving.
• C. Ear notch.
• D. Sharpie.

Answer: (C)

Permanent identification relies on a method that remains with the animal for its lifetime. Ear notch creates a distinctive, permanent change to the ear tissue, so the pattern is readable throughout the animal’s life and can be tied to records for traceability and identification in the herd. In contrast, fur dye only colors the coat temporarily and can fade or be obscured as the coat grows or gets washed. Shaving removes hair but it isn’t lasting, and a marker like a Sharpie marks the skin or fur only briefly before it wears off. For reliable long-term identification, ear notch is the durable choice.
