When we moved, however, it took us almost a year to get our address changed. At the time, you had to call or request by mail to have your info updated...and we just...never did.
When we brought Ed home and had him microchipped during his neuter surgery, we called to ensure both of their info was correct. We made sure to print off their chip information and put it in their binders for quick reference, especially if we ever need to update again.
Is your dog microchipped? Is his information up-to-date?
