But on the topic of animals, maybe the government should expend money and effort in a area where some actual good could be done, like shutting down puppy mills and backyard breeders. Though I do personally encourage altering (spay or neuter) companion animals, micro-chipping should be the choice of the pet owner, not the government.
FYI: I chose to have my dog microchipped. The implantation cost $30.00 and the one time fee to register him with the AKC National Registery was $12.50. I feel it was a small price to pay for his protection and my piece of mind.
