A 57-year-old Las Vegas grandmother was struck and killed by a car when she stopped to help an injured dog.

Valerie Roberts was struck Wednesday night while in the middle of Boulder Highway, where she was helping another motorist who had gone to the dog’s assistance.

Her family and friends told News 3 in Las Vegas they’re not surprised her final act was trying to save a life.

Roberts, who worked taking care of the elderly and disabled, was also known to take people in to her home, rent free, to help them get back on their feet.

Roberts had two daughters and three grandchildren.

Las Vegas police say the Roberts had stopped her car and gotten out to help another person who was assisting the dog.

Authorities say the driver of an approaching car swerved to avoid hitting the stopped car and hit Roberts. She was pronounced dead at the hospital.

We couldn’t find any news reports indicating whether the dog survived.

When Jane Guardascione, a 94-year-old Queens grandmother, lost her pet collie and constant companion, Angel, her granddaughter got on the phone, placing several calls to Animal Control and Care to see if the dog turned up in the city’s shelter system.

Angel wasn’t there, the agency repeatedly told her Friday.

On Saturday, though, she was told the 13-year-old dog had been euthanized at Animal Control and Care’s Manhattan shelter — the same day she arrived.

Shelter officials said Angel had collapsed at the shelter, had no identification and fit no description of any dogs reported lost. Because of her age and deteriorating condition, a veterinarian at the facility decided to euthanize Angel in an effort to prevent any additional suffering, the New York Daily News reports.

In a statement, the agency expressed ”deepest sympathies” to the family. “It is our goal to avoid euthanasia unless we deem it absolutely necessary,” the statement read.

Family members say, while Angel suffered from arthritis, she was able to get around just fine —  and was probably frozen with fear in the shelter. Jane’s daughter, Carole Miller, a collie breeder, gave her mother the dog when Angel was just over a year old. The dog was her constant companion, she said.

AC&C, which operates city shelters under a contract with the Health Department, is required to hold lost and stray animals for at least 72 hours before putting them up for adoption or euthanizing them. Exceptions are made if an animal is critically injured or gravely ill.

Outraged animal rescue groups said such mistakes are not unusual at AC&C and charged the nonprofit organization is plagued by mismanagement. In January, the Daily News reported that one rescue group sued the city because it was breaking its own law by not providing animal shelters in all five boroughs. The suit charged that facilities are overcrowded and disease-ridden and that animals are being euthanized in “unconscionable numbers” because there is no space.
