I know where I live, by law you have to have an annual vaccine for dogs and cats and animals are required to wear their id tags AT ALL TIMES. If an animal bites someone, they hold it for 10 days, only if it is what they consider a 'non-vicious' breed. 'Vicious' breeds are euthanized. I do know that there is no mandatory holding period for animals picked up (strays or loose) if they do not have the proper id. I don't know if it's like 3 strikes, you're out if your dog bites X number of times, but I would think that would deal more with the ferocity of the dog rather than possibility of rabies? Anyway, I know it is law here and did call out of curiosity to see if a waiver from a vet was acceptable and they said, 'no.' I left it at that because even so, I will get the shot for our pooches, merely for the wildlife factor here.
