I doubt there is a smaller needle. The needle is larger bc it has to be big enough for the chip to pass through, which is about the size of a grain of rice. I've had several fosters that needed chips put in. They always take them to the back to put them in but I never hear a yelp or scream. Though there will most likely be some blood.
