Either my house is haunted by a terrified chihuahua or the White's tree frog is calling. Every night somewhere between 9 p.m. and 10:30 p.m. I hear this sharp, loud "Yip." It has woke me from sleeping. The frog is in another room, I can't catch it doing this and have no other explanation unless.......some invisible person has stepped on the tail of a small dog. I don't have a small dog. Is this the Dumpy call?
