Philippine Dog Finder

Are you in favor of your dogs getting micro chipped? Well honestly I do not get its used because some of my friends had it on their dog and they said that it is not like a cell phone spy or a person tracker you used on your cell phone to check or track their whereabouts that acts like gps but the micro chipped for dogs are not working properly in the Philippines, they cannot track their dogs. Plus the fact that it is very expensive to have your dog micro chipped and still they did not find any good use for it. So I hope to get more information regarding the benefit of micro chipping them and I  hope that the very purpose of doing that will be used.
