"She continued to wag her tail. There was blood everywhere," said Mollie's owner Monica Nilsson to the local Nya Wermlands Tidning daily.
Mollie had just been out for a jog with Nilsson's partner Lars Åke and went for a lie down and rest under the apple tree in the garden when disaster struck. The flat-coated black retriever woke to find that her tail had been run over by the silent mechanical predator.
The Nilssons reported that Mollie had grown used to the lawnmower cruising around the lawn cutting the grass and usually jumped out of the way.
"She usually hops out of the way when it (the lawnmower) approaches. But we forgot to think about the tail," Monica Nilsson said.
Mollie was rushed into the animal hospital in Karlstad and was given five stitches to seal up the wound which Nilsson told the newspaper had resembled a snake's tongue.
"Don't leave your dog alone with the lawnmower," the hospital said in response to the incident.
