No chip (yet) for Bijou because she was a pup rescue (she had only had her first puppy shots administered when we got her at 14 weeks; no vet exam, no vaccinations, no deworming, no spay, etc.). She's now fully UTD on everything except being chipped -- I'd love to hear your experiences/thoughts on this. I know it's quite affordable and (supposedly) not too uncomfortable to place -- any reason not to have it done?
