If your trash service collects the garbage infrequently, you might worry about it getting stinky with dog poo.  Even when the poo is wrapped up in bags, the scent can be quite powerful, especially in the summer.  You can solve this problem by investing in a smaller, separate trash can specifically for dog waste.  Ensure it has a lid.  Place a liner in it as you would with any other can, but leave it outside, and empty it into your larger trash bin when your trash collection service arrives.  If your trash tends to be relatively stinky even without the addition of dog waste, there is little to be gained from utilizing a separate trash can just for dog waste. If you don't want to dispose of your bagged dog waste in a separate can, place it in your primary garbage bin (the big one that sits by the curb). A pet waste digester is a device that breaks dog poo down into a safe, biodegradable liquid that is then absorbed by your yard.  To use the device, simply drop the waste in the opening, add warm water, and add the digestive agent.  The exact amount of water and digestive agent required depends on the pet waste digester model you have. Installation is relatively easy, but does require you to dig a shallow hole (usually about one cubic foot) in your yard.  This allows the liquefied poo to release slowly into the yard without pooling onto the grass. Always follow manufacturer directions when using your pet waste digester. In its natural state, dog poop is not a good fertilizer, as it contains harmful bacteria and (potentially) parasites.  New technologies, however, allow you to ferment your dog poo using commercially available kits.  The fermentation process will remove the toxic elements and leave behind nutrient-rich soil.  The basic process involves mixing a fermentive accelerant, a dry mix, and water in specific amounts, then adding poo to a small bucket. After the bucket is full, dig a small hole in your yard and poor the mixture in.  Cover with soil. After about two weeks, the poo will be completely transformed to healthy soil. Pet waste fermenting systems are available in a few stores on the west coast, but can be easily ordered online. Don't use dog poo fertilizer on plants that are intended for human consumption. Many cities ban pet waste in human toilets since waste water systems cannot properly process it.  It's best to err on the side of caution and put your dog poo in the garbage.  Alternately, if you want to do some investigating, contact your local Department of Health or Municipal Waste Department and find out if it is possible to flush dog poop down the toilet. If your local waste water system allows pet poop, you could use flushable poop bags.  These bags are specially designed to break down when they come in contact with water.
Consider getting a separate trash can. Install a pet waste digester. Turn your dog poo into fertilizer. Be cautious when flushing your dog waste down the toilet.
