Purina-Dog-Content-BrandOne of a pet owners greatest fears is getting separated from their pet. Now, many shelters and veterinarians are installing identification chips on pets. It’s a hi-tech way to resolve the separation anxiety of losing a pet.

A microchip implant is a tiny integrated circuit placed under the skin of a dog or cat. The chip emits passive radio frequencies that can be identified by a scanner at a shelter where a lost pet is taken. Think of it as an invisible electronic identification tag.

Early compatibility issues between different kinds of scanners and chips have mostly been resolved. There’s now a universal scanner that reads all brands of chips. They’re helping to get missing cats and dogs back in the grateful arms of their owners.
