A businessman sank his teeth into a cricket coach and left him covered in bites during a vicious row at a Wetherspoons pub.
The cuts were so deep that doctors asked victim Jarrad Davies, 23, what type of dog had attacked him, a court heard on Monday.
Anthony Wade Mears, a prominent Saudi-based businessman from Aberdare, Wales, launched the horrific attack after Mr Davies inadvertently bumped into him during a pre-Christmas night out at the Yr Ieuan Ap Iago pub in 2018.
Speaking to Wales Online , his victim described him as "like a bull who had seen red," as he bit him four times.
"When we landed he started biting me – it was like a dog. I was left in one hell of a mess," Mr Davies said.
The attack left Mr Davies, a child support worker, unable to work for more than a month.
He was put on a 40-day course of medication due to infection risk and says medics at the Prince Charles Hospital in Merthyr, where he received treatment, thought a dog had been responsible for his injuries.
The former Welsh youth cricket player was enjoying drinks with his brother Nathan and another friend, John Spencer, on December 23 when he encounted Mears, 51, a sentencing hearing at Merthyr Tydfil Crown Court was told.
"We bumped into him and he gave us some chat," said Mr Davies.
"I saw him coming. I was in front and just happened to be the next person in line. I put my hands up and told him: 'It's the 23rd of December, leave it well enough alone'."
Witnesses say Mears turned to friends and said "Hold my f****** cigarette" before facing Mr Davies and attacking him.
He proceeded to bite his victim in the stomach so hard it left him with a wound that looked "like a second belly-button".
Mears initially denied the charge, saying Mr Davies had got his injuries in a separate fight.
But after seeing the exchange had been captured on CCTV footage, he pleaded guilty at the opening of his trial.
Mears, a father of two, has now been jailed for 21 months for unlawful wounding.
Addressing him, Judge Lloyd-Clarke said: "It seems that Mr Spencer bumped into you accidentally and an incident develops. Your reaction is to become violent."
Defending, John Ryan said Mears had been born into a "respectable family" in Aberdare where his father was a detective inspector for more than 30 years.
Mr Ryan said he was not a man "born with a silver spoon in his mouth" but someone who had worked his way to the top.
Mears qualified as an accountant before becoming finance director at a number of international aluminium recycling firms.
He was most recently based in Saudi Arabia, where he was president at the Ma'aden Aluminium Company plant managing more than 800 employees.
Delivering the sentence, Judge Lloyd-Clarke said: "This was clearly a repeated offence because there are four bite marks. You used the equivalent of a weapon when you used your teeth."
A custodial sentence was her "only course of action," she added.
Mr Davies' dad Todd Davies, who sat in the public gallery for the sentencing, said his son had refused to go out for months afterwards and was all over the place during his treatment.
Speaking outside the court, he said: "This guy is almost my age. He shouldn't be doing that.
"He is running a company with 800-odd employees. You should be operating at another level of professionalism.
"You try and bring your kids up knowing what is right and wrong and with respect. I'm proud that Jarrad didn't react violently but he ended up coming off much worse."
Mr Davies, a keen sportsman who plays cricket for Lisvane and was awarded young coach of the year in 2018, was emotional as his attacker was sent down.
"I'm overwhelmed and just glad it's done now," he said.
Mears will serve half of his sentence in custody before he can apply to be released on licence.
