Food or Medical:  Nutritional deficiency is commonly believed to be one of the main  reasons for poo eating, so it is important to rule this out first. Sometimes the richer the food that has been eaten the more chance that the dog may find those faeces palatable. I have found that dogs on Burns dog food, rather than other brands appear to eat their own or other dogs faeces more than other dog foods. Medical issues especially in older dogs such as pancreatic or intestinal problems could stimulate Coprophagia. Even overfeeding especially food with a high fat content can sometimes spark this behaviour. It has also been suggested that eating faeces could be an aid in food digestion, in other words a probiotic which encourages healthy flora in the gut.


This can work with some dogs will depend on how obsessive the dogs need is to eat the faeces. Though I have had to treat a number of dogs that are severely Intraspecific Coprophagic. These dogs eat very old faeces or faeces from dogs that are ill from intestinal problems or with very loose stools.
Or using food as a lure though in some cases the dog may combine the lure and praise as something it gets when eating faeces. A cat has died in Germany from eating an infected bird; therefore this virus has shown it can cross the species.

The intestinal phase of this nasty disease occurs only in cats (wild as well as domesticated) therefore transmission to dogs is by ingestion of oocysts (in cat faeces) or bradyzoites in some raw or undercooked meat that has not been pre-frozen.
Obviously this would be for dogs that were eating their own faeces, or the faeces of another dog in the same household.
