Break Undesirable dog habits
It is fairly natural for many breeds ofto eat the feces of other animals. Both young and on diets do this with frequency. They seem to be trying to recover leftover nutrients and calories from undigested particles in the stool. Some even develop the habit of eating their own feces. If you see your dog doing this try saying "No" and if that is not enough you can use a water pistol to reinforce your command. To break this habit you can buy products that you put on your dog's which leave a undesirable taste on their feces or you can put a very hot sauce onto their feces that are in the yard to discourage further practice of this dirty and disgusting habit.
