It goes without saying that a microchip can and has saved many lost pets.
This morning momma read in her Foster/Adopting board that Adopters and Rescuers can register the microchip number at Petidco. They accept all microchip companies. Without this registration the microchip number is invalid in Canada when scanned. It is $22 for rescuers and $27 for adopters, and this fee is for the lifetime of the dog. If the adopter registers the number they can put the rescue number as the alternate contact. Here is the link
Definitely worth it for everyone to do this!
