Hi, as a Groomer/Vet Tech I understand your concern. The needles used for microchipping ARE scary looking. I've always insisted on waiting until my females were having another procedure to have this done - until Halo. Believe me, she's a screamer ! I was amazed she didn't even flinch !! I feel bad that I convinced so many dog owners to allow me to lightly sedate their dogs for this to be done ! Halo was 6 months old when I had her chipped. Good luck
