Check out this needle i used to inject a microchip into my dog. Granted, it was an SC injection but it I was scared for him. It made a really naty cracking noise when it broke threw the skin. It barely bothered him but god damn!!! The bitch i have got hers done at the vet and they charged me $50 i think. I just ended up ordering the chip when i bought my fina and it only costs $9. I hate the vet almost as much as the dentist.
