The Chaska Fire Department said it quickly extinguished the fire. Authorities determined that the dog, a pug, had caused the fire after the strong scent of urine was found emanating from the outlet.

Initially, it appeared unlikely that the pug would be able to lift its leg high enough to hit the outlet. But closer inspection revealed that the pug likely climbed atop items that were on the floor, the department said.

It is not known how much damage the house sustained. Authorities also gave no word as to the health of the pug.
