This won't work for everyone. There is a strip of woodland beside our dog's yard. I scoop it up and fire it over the fence into the wooded area.
Smell is not a problem. In the summer, the piles quickly decompose. Fungus, and bugs quickly break it down. It takes less than a week for a dropping to look like a pile of brown sawdust.
You may get a slight waft of the odor when it is flung over the fence, but that's it. We used to bag it and put it in the dumpster, but whenever the top was lifted to deposit trash the stench was overpowering, particularly in hot weather.
Over the fence works for us.
