You'd be surprised how many dogs go missing each year around the world when their perfectly good owner has a brief laps in concentration and the dog ends up running away after a squirrel or other animal never to be seen again.
You might think that it will never happen to you because you're too careful and never take your eyes of the dog, but believe me it will happen a lot quicker than expected and could have devastating consequences.
Although your dog might have run off and disobeyed your commands when they went this doesn't mean that you're a bad trainer or have no control over your dog, but these things do happen and unless your dog is an extremely well behaved and trained dog not much can stop them from chasing something when they're in the mood.
This is where the micro chip comes in; the dog micro chip is a small soda limed glass tube that gets inserted into your dog containing a chip, antenna, and capacitor. These are used together to hold vital information about your dog or the dog in hand so that people all over the world can trace the ownership of this dog back to you at your home.
The chip does not hold a complete profile of your dog but only a I.D. number that then gives access to the information via a database which can be reached from the majority of pet and dog specialists, kennels and shelters all over the world.
It takes just a few seconds to insert the chip and it hurts your dog no more than a regular vaccination procedure and for this your get the security and ease of mind knowing that your dog can be reached and found anywhere in the world, and for me that's worth it.
