AS of today ferocious XL Bully dogs have been banned in England and Wales, with owners facing jail and their beasts being destroyed.
The breed was deemed illegal after 11 people were killed by the hounds in the last three years, and many others injured in horror maulings.
But as of now, all beasts must be registered - with yesterday being the final deadline.
Owners and their dogs now face strict punishments without a certificate.
Around 40,000 of the large bulldog-type American breed were expected to have been registered before the deadline on Wednesday afternoon, but there may be thousands without certificates.
For those who missed the deadline, streets could be overrun with illegal and unregistered hounds.

Dangerous Dogs Act explained
After eleven horrific attacks in 1991, Home Secretary Kenneth Baker promised "to rid the country of the menace of these fighting dogs" by introducing the Dangerous Dogs Act.
The law is often considered controversial as it focuses on a dog's breed or looks instead of an individual dog's behaviour, and fails to stem the rise of dog attacks.
According to the RSPCA, over a third of the people killed by dogs since the act was brought in were attacked by legal breeds.
