I live in Yucaipa, CA, not far from Riverside.
I live in a somewhat big city, but no where in Georgia do you have to register your dog.I live in Riverside, CA (USA). I'm surprised you don't have to register your dogs. I do agree with threenorns that you will eventually have to get them licensed. Is your town/city small?
Oh and here in Riverside it's also law that you're pets are microchipped. But they don't enforce that one as much.
Before I joined this forum I had never heard about registering your dog or laws for having to vaccinate. I'm going to look up laws on animals in Georgia and see if I can find anything about registering them. Where I live you don't have to get your dogs rabies shot unless you take them to a dog park and some other places. But if your dog does not a a rabies shot and attacks another animal or human they have to be quarantined at a vets or pounds.I find that so odd! Do you not have the option to register them or is it not available?
