To show legal pet ownership, you'll need to keep proper documentation that proves your rights and responsibilities. This documentation helps protect you and your animal companion in any dispute, travel situation, or emergency. I have been able to help my clients be reunited with lost pets through updating their records. The important paperwork that you maintain will show that you have legal guardianship according to the law.

Microchip Registration provides permanent identification that's essential. Be sure to keep your contact information current with your microchip registration company. Having verification from the vet that the microchip is functioning properly yearly will confirm its proper usage. I have regained possession of a lost dog within hours of losing her due to the current information on the microchip registration. This technology ensures and proves ownership that can not be contested.

Maintain hard and digital copies of every document about your pet in a dedicated pet portfolio. Enter records as soon as you move or make a change of ownership. Store digital copies in a secure cloud location. This organized approach prevents complications in case of emergencies or legal wranglings concerning your companion animal.
