Protect your pet from becoming hopelessly lost - for free. Now through Sunday, Aug. 25 you can get free microchipping when you get any other veterinary service at the Humane Society Animal Health Center. The offer is only good on Sundays at the center, which is open 8:30 a.m. - 3 p.m. on those days. Microchipping is a process which implants a device about the size of a grain of rice in the nape of your pet's neck. The chip can be scanned and traced back to the owner if the pet should become lost.
