Dogs Allegedly Cut Open in an Unlicensed Backyard Surgery Ring — Demand the Clinic Operator Face Every Charge

Target: Brian Mason, District Attorney, 17th Judicial District, Brighton, Colorado

Goal: Person accused of operating an unlicensed veterinary clinic and confining dozens of animals in inhumane conditions must be prosecuted to the fullest extent of the law.

Behind what looked like an ordinary residence, investigators allege they found a place where vulnerable animals endured needless suffering instead of receiving care.

Commerce City police executed a search warrant after receiving multiple reports of suspected animal welfare violations. Inside the property, investigators apparently found 31 dogs, two cats, and two guinea pigs confined in overcrowded, poorly ventilated backyard enclosures contaminated with accumulated waste. Officers also reportedly found the body of a deceased dog concealed inside a residential trash container.

Authorities allege the property’s occupant had been operating an unlicensed veterinary clinic, performing complex surgical procedures on animals without legal authorization or professional licensing. The surviving animals were removed and transferred to emergency shelters for treatment, rehabilitation, and behavioral assessment. The accused has been arrested on multiple felony animal cruelty charges, along with additional criminal offenses.

Performing invasive medical procedures without proper qualifications while housing animals in dangerous conditions represents an extraordinary breach of trust. Families seek veterinary care believing it will relieve suffering, not expose animals to greater harm. If the above allegations are proven true, the defendant must face the most severe legal penalty.

PETITION LETTER:

Dear District Attorney Mason,

The findings uncovered in this investigation have profoundly disturbed animal welfare advocates. Investigators allege dozens of animals were confined in unsafe, unsanitary conditions while unauthorized surgical procedures were carried out inside a residential property. Authorities also recovered the body of a deceased dog during the search.

Your office now has the opportunity to pursue a complete and impartial prosecution based on veterinary findings, forensic evidence, investigative reports, and witness testimony.

Please ensure that the defendant is prosecuted under the fullest provisions of Colorado law. Animals allegedly subjected to unlawful medical procedures and preventable suffering deserve justice, and a strong legal response will help deter similar operations.

Sincerely,

[Your Name Here]
