You cannot. If you have a dog, make sure you are picking up your dog's feces every day. Then go over to your neighbor's house and very politely ask them to please pick up their dog's feces as it stinks. Even offer to help out when you go over there. Just be very nice when you ask them to do this, tell them that you do not want your own yard to smell badly for them and that is why you keep your dog's feces picked up. Also explain to them the dangers of letting feces lie around for their own health and their dog's. By picking up the feces on a daily basis they will cut down the risks of getting roundworm eggs, thereby infecting themselves and their dog. So it is safer for the owners and the dogs. Tell them to watch that show on TV called "Monsters Inside of Me". I bet they will pick up their dog's feces twice a day if they watched that.
You are not going to be able to do this unless you simply keep the dog away from the feces. Why? Because to the dog the feces is a treat and taste good. The good news is that as long as the mini piglet is healthy, its feces is healthy, too, and it won't hurt the dog. Just make sure the dog has access to it's own good food, which is, of course, more nutritious than the feces. Then you can thank the dog for cleaning up the feces for you - just don't let him kiss you right afterward.

Food grade or medical mineral oil will mostly increase the passage rate of intestinal contents, so your dog may have loose stools or diarrhea while the mineral oil is working its way through. The oil is often visible on the feces as well as a clear shiny liquid or coating.

This is not a good sign, normally dogs feces should be somewhat colored and semi hard. It could indicate food needs to be changed.
The color of feces is caused by something he is eating.
Actually, Dog feces is very harmful to your plants. Grazing and grain eating animals are fine and that is why you see chicken feces fertilizer a lot but not many other animals.
If your dog is eating it's feces, that likely means that he is eating too fast and therefore is not properly digesting his food, so there are still nutrients and a good taste left in his feces (that's why he wants to eat it). You have to make your dog eat slower.
