Chipped

Today we had to go back to where the pups were born in order to have them chipped.
It is a small chip, same as on your credit card implanted in the neck of the pups.
If you have the proper tools, like a scanner special designed for veterinarians, you can read out the chips and see name, owner, number and so on.
These three brothers didn't even noticed to be chipped, they were too busy with playing with each other after one week alone with their new owners.
