Dear Terry, this morning the furnace guy came. Mom says that's the heat machine. He was in the basement. I kept barking to let Mom know HEY there's someone in the house!!!! I listened to everything. I went right to the vent where I could hear him best and barked and barked. Someone had to let him know this was OUR house! I could hear Dad talking to him. I wasn't allowed in the basement even though Dad was there. Mom said it's ok he's just giving the furnace a tune up. I don't know what that is but I kept the house safe. I ran to the window when he left to make sure he was gone. He looked nice. Guess maybe I should have wagged more and barked a little less as the saying goes. But that's what I do, I keep the house safe. The cats don't make any sounds when things go on so I have to make up for it! Love and Woofs, FredDog.
