This is the moment a man was hit in the face with a hammer during a violent attack in Weston-super-Mare.
CCTV footage of the assault was released by Avon and Somerset Police after Paul Ashe was jailed for 24 years for his crimes.
Last week's hearing at Bristol Crown Court was told the 46-year-old also knifed two other victims while on bail for the first attack. The men sustained injuries to their faces and bodies.
During the footage, Ashe's dog is seen fighting with another pet before the owner then approaches Ashe, of George Street, Weston, who is sitting on a pub picnic bench.
He then jumps up and strikes 53-year-old Simon Bradbury across the face, leaving him with a fractured cheekbone, eye socket and broken nose.
Ashe admitted possessing a knife and breaching a suspended jail term for battery.
Judge Mark Horton jailed him for 24 years, with an extended licence period of four years.
You can watch CCTV footage of the attack below:
Hannah Squire, prosecuting, said violence flared outside the Red Admiral pub in Weston in April last year after Ashe’s dog bit another dog being walked by Mr Bradbury.
When Mr Bradbury approached Ashe afterwards, Ashe swung a hammer into his face.
Mr Bradbury suffered "catastrophic" facial injuries and had to have stainless steel tubes inserted in his face to assist breathing.
He wrote an impact statement in which he said he had been left suffering dizzy spells, was on very strong painkillers, was unable to drive and lost financially.
