I did the micro chipping for all my dogs.  I wait till they are bigger atleast 3-4 lbs.  I had one that was 2 lbs and stopped growing, he got one eventually, he didn't even notice me.  I surely notice.  Have you ever gotten your belly button pierced I'd imagine that's what it feels like, but less pain since you aren't leaving a gauge in to keep the hole open.     |
