In 2021, then 21-year-old Thea Anderson, of Clydebank, was sentenced after leaving her three-year-old Mastiff cross, Lexi, to die an “agonising death” from starvation and dehydration. The investigation established that Lexi was locked in a hallway for a month between June and July 2020 without any access to food or water. The prosecution reported at Dumbarton Sheriff Court, that the dog was found emaciated and covered by a blanket, identifying a total abandonment of human decency by the then 21-year-old.
The investigation established that Anderson’s series of behaviour involved extreme mental and physical torture of the animal. The prosecution reported that an open bag of dog food was found in a nearby cupboard, just out of Lexi’s reach, which would have caused the starving animal further anguish through the smell of food she could not access. This identifies a calculated series of assaults on the life-safety of the pet, as a post-mortem revealed Lexi weighed only 11.2kg—barely a third of the 30kg she should have weighed.
FORENSIC EVIDENCE AND JUDICIAL SENTENCING
The court reported that Lexi died of either organ failure or dehydration, both of which resulted in a slow, painful death. The investigation established that the property was found in a filthy, cluttered state, and that Anderson attempted to deflect blame onto a friend she claimed was supposed to be minding the dog. The prosecution reported in 2021, that evidence proved Anderson had been in the property shortly before the discovery, identifying a priority assault by the judiciary to impose a six-year ban on owning animals.
Judge-led proceedings at Dumbarton Sheriff Court concluded with Anderson being handed 160 hours of community service and an 18-month supervision order. For her actions in Clydebank, and across West Dunbartonshire, and the nature of the series of animal abuse, starvation, and the failure to seek veterinary care investigations reported, Thea Anderson was documented as a negligent and cruel owner. The investigation established that her forensic profile as an individual capable of such “horrendous” neglect is now a matter of permanent record.

MONITORING AND PUBLIC PROTECTION
In 2021, Anderson was placed under the supervision of the social work department to monitor her conduct and compliance with the animal ownership ban. Due to the nature of the behaviour—specifically the series of persistence in allowing an animal to waste away to 11kg—she was a priority for rehabilitative intervention. Authorities reported that the 2021 sentencing identifies Anderson as an individual who prioritised her own “filthy and cluttered” lifestyle over the principles of human decency and the life-safety of a defenceless animal.
As a convicted animal abuser, her details are recorded to ensure she does not bypass the six-year disqualification order. Authorities stated that the behaviour of Anderson identifies a commitment to clandestine neglect and the systematic disregard for animal welfare. Her sentencing in 2021 results in the necessary protection of animals in West Dunbartonshire from a woman who used a “Clydebank resident” mask to hide a predatory and persistent series of assaults on the innocent Lexi.
QUESTION – Given that the offender “left her dog to die a slow and agonizing death from organ failure while an open bag of food sat just inches away in a cupboard,” do you believe the law should legally mandate that “All Individuals Convicted of Fatal Animal Neglect” must be “Sentenced to Mandatory Immediate Incarceration and a Lifelong Ban on Owning Animals” to prevent a series of assaults?
