Micro-chipping will be done at 8 weeks of age.
I use Nano-chips and I register them under my kennel name. When you get your pup, you will get the paperwork to register it under your own name too.
This costs nothing extra to you. I pay for it because I want to be certain my pups are protected if they get loose, or if someone steals them. Better safe than sorry!
IF YOU DON'T WANT A MICRO-CHIP:
Please let me know in advance. I will not chip your pup.
