The areas around Watford where the most XL Bullies live have been revealed by new data.

Owners must have a certificate of exemption for their restricted dog after law changes came into force from January 31.

Figures on approved applications by postcode, obtained by The Spectator, showed there are 36 XL Bullies living in Oxhey, South Oxhey and Carpenders Park (WD19), ranking it the 551st highest neighbourhood in the country.

WD25, including Garston and Leavesden, also had the most around Watford (33), while 26 are living in WD3 across Rickmansworth, Croxley Green and Chorleywood.

There were 20 approved applications in North Watford (WD24), compared to 19 in Kings Langley (WD4) and 14 in Bushey (WD23).

Central Watford, west Watford and Abbots Langley were not represented as there was no data for areas with fewer than 10 approved applications. 

Since the restrictions were brought earlier this year, Hertfordshire Police seized a dog from the Woodside area on April 29 over fears it could be an unregistered XL Bully.

A spokesperson for the force confirmed at the time it was unregistered and was returned to its owner with conditions before the case is dealt with by a civil court.
