WICHITA, Kan. (KSNW) — The Kansas Humane Society (KHS) and WSU Tech are hosting a free vaccination and microchip clinic for cats and dogs 6 weeks or older this weekend.

It will be taking place from 10 a.m. to 1 p.m. on Saturday, July 30, at Evergreen Recreation Center, 2700 N Woodland.

It is a walk-up clinic, so no registration is required.

The first 200 pets at the event will receive free microchipping and free vaccinations, provided by PETCO LOVE.

All cats must be in a carrier, and all dogs must be on a leash. There is no limit on how many pets one person can bring, but if you plan on bringing more than two, you must have at least two handlers.

According to the American Kennel Club (AKC), a microchip is roughly the size of a grain of rice that is injected under the loose skin between your dog’s or cat’s loose shoulder blades. It is a radio-frequency identification transporter that, when registered by an owner with a national pet recovery database, can be scanned by a vet or shelter to reveal an ID number that can tie the pet back to its owner.

According to AKC Reunite, “Pets with microchips are up to 20 times more likely to be reunited with their owners.”

A microchip will permanently identify a lost pet if their collars, harness and/or tags are removed or broken off.
