What can I do with a dead dog?

One of my families dogs died this morning we honestly dont know what to do with the body. The dog is really big and weighs around 80 to 90 pounds. I know I can call animal control or my local vets office but its late and everyones closed for the most part on sunday. I hate him being out there and the flies are gathering on him but he's to heavy to do much with. I wish I could spray him or something som the flies would leave is driving me insane.
