I think microchipping pets is a good practice. However, like many good practices, some people get anxious when good practices become mandated practices, such as seat belt use, or helmet wearing. It becomes even more questionable when a good practice is enforced by a federal agency. I would prefer that microchipping be encouraged thru education (PSA's, public events by animal shelters), supporting services (microchips including with adopted pets, special price incentives), and other positive promotions.
Oh I see, my families don't believe in microchip and they use collar with tag, however, sometime, the collar could lose in anywhere.
Yup failed, it was a recent chip, you could feel it. When it was inserted, they scan and show you its reading before you leave the vet, we went back about a month later for the second set of shots and the microchip wouldnt read. We never went anywhere and pup was at home with us 24/7 and a month later it didnt work, The vet said they do just die out and it is not uncommon. We have experienced 3 microchips that died out, all from different vets ( some were done at a pet store during a special ) we have several friends in the dog club/shows that had the same thing. So everyone, if you are concerned about your pet getting lost, always have the chip read when you go to the vet to make sure it still works.
The pet owners could sue in the court based on 5th or 14th Amendment, all way to supreme court, so I'm very interested about legal challenge with mandatory microchips.
Right now, I don't think any cities pass the mandatory microchips yet and my argument is moot.
