My dog has one of the BIO chips. It is not read by GPS, it simply contains a unique number that is read by a hand reader. Her (Charlotte the wonder pup) number is registered with the AKC that links her to me. Most kennels and vets have a reader. The idea comes into play when, if, she gets lost.
To get back on the original thread, I would like to start taking my dog with me GeoCaching. She loves being out in the woods. If someone does have some training methodologies, please let me know. I would love to utilize her capabilities on some microcaches yet to be found!
Thanks,
Sarp
