Getting your dog microchipped is not that expensive and can be useful if your dog gets lost. On average, the cost of microchipping your dog should be around $45-50. This money includes the vet procedure, online registration process, and the cost of the actual chip. The cost of microchipping a dog does not depend on the size of your dog, and the procedure remains the same. Also, if you have adopted a dog from a rescue center, you may find that your dog may already have been microchipped. Many such organizations mandate microchipping their dogs before letting them be adopted.
