Okay, this one is going to cause disagreement and discord, but will it do any good for dogs in the long run? Enforced microchipping is controversial, but I can't help thinking it would solve many problems - dog theft not the least of them. It would of course also allow the tracing of dogs back to breeders, so if health issues keep cropping up with dogs from a particular source, it will be evident and provable. Puppy farms are an obvious evil and must be stamped out one way or another.
