Two Great Pyrenees dogs were stolen between Friday and Sunday night from a property in the first block of Springbrook Road in Afton, sheriff's Deputy C.H. Jessie said in a report.
The male and female dogs were inside a fenced-in enclosure in the back yard of a house.
The male "has black markings like a mask on his face," the 47-year-old owner told deputies.
The dogs are valued at $1,200 each.
