Motley was microchipped the same time he was neutered, under the vet's recommendation, and I'm glad I did it is a good size needle. We used Avid and the cost of the microchipping was only $20. I then had to pay an additional $20 to register the number. A small price to pay if my baby was ever lost. He was six months old at the time, he's now 14 months old and we haven't had any issues at all with the chip |
