Microchip to stop dangerous dogs
23 April 2012 Last updated at 17:36 BST
Dog owners in England will soon have to pay for their new born puppies to be fitted with a microchip.
It's a government plan to crack down on dangerous dogs.
The chip fits under an animal's skin and would contain information about their owner, to make the human easier to be traced by the police if their dog attacks someone.
5000 people a week voluntarily chip their dogs to make them easier to find if they get lost.
