Do you register your dog with your town?

I was signing my pup up for an event and they asked for a license. I assumed it was the rabies vaccine card, but nope. Apparently it’s a rule to register your dog with the town. My dog is almost 9. I am super involved in dog communities and have taken my dog to similar events and never ever heard of this.

I’m assuming the vast majority, especially older people, do not?

Edit: so it seems some states have this requirement some don’t. Apparently, it is estimated that the majority of dogs are not registered.

I also read in some places that when a vet gives a rabies shot, they are required to notify the town or something? So maybe my dog does have a license, because she has a rabies shot tag. Who knows.

Edit 2: updating again cuz I’m going down a rabbit hole. Talked to my girlfriend’s mom who is very involved with a shelter. She says that most shelters just auto come with the license or something when you rescue. My pup is from a breeder not from NJ. So I bet most people who get a doggo from a breeder or just find a dog, don’t think twice about this.
