Collar tags can break or become unreadable and tattooing can become illegible. So, if you want to improve your pet's chances of getting home fast and safe in case it goes missing, microchipping is your best option. The Humane Society of Greenwood is offering a microchip clinic to the public on Saturday, May 21, from 10:00 a.m. and 1:00 p.m. Cost is $15, includes registration with 24PetWatch.
