Leyna has her microchip but I know from personal experience with Zappa that they go out. I took Leyna in and had her tattooed on her inner thigh. I added the tattoo to her AKC registration, registered it with her Home Again microchip (you can add it on when you register the chip), registered it with UScA, and registered it with the SV. I like having the double "coverage" on her.

At the rainbow bridge:
Zappa 12/27/00-1/23/12 You are my heart, my soul, and my best friend. You will be with me always.
Zeus 5/9/12-8/13/12 You taught me strength. Run free.
