This event is expected to be very busy, so make sure you and your pet are prepared to spend some time in line! There is no limit to the number of furry friends accompanying you for this service. The microchipping, as well as the national registration are both free of charge. To ensure everyone's safety, dogs must be leashed, and cats must be in carriers. This event is made possible through the Best Friends Animal Society Prince & Paws Shelter Collaborative Program.
