Two police cars whizzed by Norma Onstad Monday afternoon as she headed toward her daughter's Tonka Bay home to check on some newborn puppies.
Moments later, Onstad learned why the police had been in such a hurry.
She watched in horror as flames shot out of the two-story house on the 100 block of Lakeview Avenue following an explosion. There were five dogs inside.
Miraculously, one of them, a female Labrador retriever, survived, said Scott Gerber, chief of the Excelsior Fire District. Her four puppies died.
No one was injured in the blast, which occurred just before 4 p.m. The homeowners, Scott and Michelle Schmitt, were on their way home Monday afternoon after spending some time at their cabin.
Onstad was on her way to check on the puppies, which were born Friday. "One was not doing very well," she said.
Gerber said officials have not determined the cause of the fire. But relatives at the scene suspect a space heater might have been to blame.
The dog and her litter were being kept in the garage with a space heater to keep them warm.
