A Denver dog daycare owner has been criminally cited for animal cruelty after a dog in his care died inside his vehicle. Ted Gualtier, owner of Happy Tails Happy Dog, LLC, had the dog left in his vehicle on August 26 and received the summons from Denver Animal Protection, and the case is now headed to county court even as his business continues to operate.

Gualtier was cited for animal cruelty after the dog died following a period left in his vehicle, according to FOX31 Denver. The Denver Department of Public Health and Environment said the citation will be handled in Denver County Court, and the department emphasized that animals should never be left alone in a car for any period of time. Happy Tails Happy Dog operates out of 4352 Cherokee Street in North Denver, offering daycare, boarding, and grooming services, according to a Facebook post describing the business.

Owner Says He's Devastated, Cites 14 Years Without Incident

Gualtier said he was devastated by the dog's death and that he personally reached out to the dog's family to offer his condolences, per the station's report. He said he has cared for hundreds of dogs over 14 years of operation without a similar incident, and that he is now conducting a full review of his operation. His attorney, Andrew J. Contiguglia of Miller and Steiert P.C., is representing him in the matter. Gualtier said he will not comment further at this time out of respect for the family and the ongoing legal process.

Under Denver's own animal cruelty framework, confining an animal in an unattended vehicle under conditions that endanger its health due to heat or lack of ventilation can bring fines up to $999 and up to 300 days in jail, per Prime Time News. Separately, Colorado Revised Statute § 18-9-202 makes confining an animal in a vehicle in a cruel or reckless manner a misdemeanor, carrying penalties of up to 364 days in jail and fines up to $1,000 for a first offense, according to Justia.

Why Cars Turn Deadly So Fast

Temperatures inside a parked vehicle can rise nearly 20 degrees within just 10 minutes, according to research from the American Veterinary Medical Association. Interior temperatures can exceed outdoor ambient heat by more than 40 degrees within an hour. Because dogs regulate body heat through panting rather than sweating, interior temperatures above 104 degrees Fahrenheit can rapidly trigger acute heatstroke, organ failure, and fatal heat stress, veterinary medical research shows.

Denver Animal Protection issues seasonal warnings about pets left unattended in hot or unventilated vehicles. Residents who see a pet locked in a hot car can contact Denver Animal Protection at (720) 913-2080.

State Licensing Adds a Second Layer of Scrutiny

State Licensing Adds a Second Layer of Scrutiny Beyond the county court proceeding, any state regulatory implications for Happy Tails Happy Dog remain unclear.

The broader regulatory response and the location of the dog's death remain unspecified. Happy Tails Happy Dog remains open as the criminal case proceeds.

Part of a Wider Pattern in the Pet Care Industry

Part of a Wider Pattern in the Pet Care Industry Denver's case follows similar enforcement actions elsewhere this year. In May, a Texas pet daycare owner and an employee in Hays County faced criminal cruelty charges after dogs died of heatstroke during van transport, Hoodline previously reported. Other reports have described dogs being found in or rescued from vans. These incidents underscore the risks associated with vehicle transport and unattended animals.
