Yes, I have my Rhodesian Ridgeback chipped. I have seen it first hand. My neighbor and I found a loose dog. We took it to the vet and sure enough it had a chip. Easy process to locate owner. My Ridgeback is chipped. Had it done while living in Pa. Now live in Florida. In Pa. if you chip you do not have to buy a license every year. Here in Fl. where they get you for even breathing the air there is a charge. Fl. does not recognise the chip regarding licenses. It is only for protection of the animal. It does work but, I have to wonder if someone finds a beautiful animal that they would like to keep would the chip matter unless, they took it to the vet and for some reason the animal would be checked and found to have a chip. Still.. I feel better knowing it is there.
