Do i need to have my dog registered to microchipped?

No, you dont. Im a vet tech and work in a clinic.

Maybe at the humane society but any veterinarian will microchip your dog without being licensed.

No you can get your dog microchipped. Even if he or she is not licensed but it's still a good idea to get your dog licensed too

Yes

All digs need to be licensed. Its the law.
