Is your yorkie allowed out at night? That's when great horned owls hunt. It's also highly likely you have two owls out there. A male and a female. Typically a mated breed stay in the same area together. He will call first...then listen...she'll call back. There is a difference in the tone between the two sexes.
We had a pair that lived right by my house for years. I actually liked watching and listening to them and read a lot about them.
One use to perch in a dead tree at the river's edge next door...when the neighbor had the tree removed...is when the owls moved on.
