My dog and cat have microchip implants, am I still required to have them wear a collar and tag?

No. A pet that is registered is required to either wear a collar and tag or have a microchip implant. However, it is always a good idea to have your pet wear a collar and tag that identifies his owner. Animal Control Officers may not be the ones who find your lost pet. If your pet is wearing a tag and collar bearing your name and contact information, your pet is going to be back home sooner.
