Seven dogs Police took control of the dogs after the retired vet was fatally mauled in his own garden.
The group of dogs believed to have carried out the attack Antony included Harrington's terrier and six other dogs owned by a friend who was living with him.
'The incident is extremely disturbing — nobody knows why the dogs turned on him,' a source said The Sun.
'He was discovered in the garden with shreds of his clothing scattered on the grass.
'His family is devastated and hopes the investigation can provide answers about what occurred.'
The dogs involved were reportedly multiple large Bernese Mountain Dogs and Harrington's own sizeable, black Russian terrier.
Medical personnel and then police were called, but 77-year-old Harrington was pronounced dead at the scene.
A 75-year-old woman has been arrested on suspicion of owning a dog that was dangerously out of control and has been released on bail.
Warwickshire Police stated: 'At 6.04pm on November 25 2023, paramedics contacted police to report a man in cardiac arrest at a residence on Packington Lane, Meriden.
'The man in his 70s was pronounced dead at the scene. He had sustained bite injuries, which were determined to be the cause of death.
'Seven dogs were taken from the scene and a 75-year-old woman from the Coleshill area was detained on suspicion of owning a dangerously out of control dog.'
'She has been released on bail while the investigation continues.'
Mr. Harrington, also known as Tony, operated his own animal medical practice in Birmingham beginning in 1980 with his late wife Louise.
He was a steam locomotive enthusiast and contributed to the restoration of a 1914 engine.
A notice of his passing in the local newspaper described him as a 'cherished husband' and 'dear father' who passed away suddenly, with a request that any donations in place of flowers be directed to Cancer Research UK or the University of Glasgow Trust (for the benefit of the Glasgow Veterinarian School).
His funeral took place in Coleshill last month followed by a private cremation.
