I had a similar ( but just as aggrevating) problem with a neighbors dog. He would put the hound (black lab)out at 4:30 am every day to do his craping etc. He wouldn't allow the mut in until 7:30 am. The dog would start barking non stop to get in and he would ignore it. Besides crapping in my yard, the barking became aggrivating as we didn't have to get up that early. I discoverd the dog was terrified of firecrackers, large or small. One morning in the summer the dog did his thing and I scooped it up and tied it to his collar. I lit a couple of firecrackers and the dog took off for his home, and when his master didn't let the mut in, he scratched through the sreen door on his slider. The neighbor knew exactly who did the deed as I had words with him over his dog, but never left his dog out again! Mission accomplished!
