Owners across the UK face being hit with a fine for not adding a significant detail to their dog's collar.
It is illegal for a dog to be in a public place or on a highway without a collar that includes the name and address of the owner attached using a plate, badge or tag. Even dogs who are microchipped must have these details.
Experts have warned people could also be at risk of having their dog seized and could even face a prison sentence if they don't adhere to these rules.
