Whether it is grass or any other inedible substance, the fact that a dog eats unsuitable things can be the result of some digestive discomfort, or many diseases. On the contrary, the ingested grass may be carrying many parasite eggs and larvae, and is therefore likely to contaminate the dog, not rid it of any digestive worms. If this is often true in the sense of “he makes himself vomit”, it is not necessary to believe that the dog acting in this way “is deworming itself”. Note: according to a popular belief, “the dog who eats grass purges himself”. While some have reported that eating grass allows the dog to make up for deficiencies, this hypothesis now seems obsolete, since even dogs with a perfectly complete and balanced diet exhibit this behavior. It is in fact an instinctive, ancestral behavior that allows the dog to vomit, and thus to relieve itself of all gastric heaviness. The interpretations given to eating grass are varied and varied. Regarding coprophagia in particular, a current hypothesis would be that dogs would act in this way by mimicry, having seen their handlers pick up their stool. Some dogs may also ingest their own droppings or damaged objects, in order to remove the object of possible punishment (often in memory of past reprimands). Dogs can do this out of frustration, boredom, anxiety, or to attract the owners ‘ attention. Pica in adult dogs may have a “purely behavioral” origin. In the adult dog, pica is however not normal, and is to be taken with the utmost seriousness, given the risks to your dog’s health that this may represent (see below). Pica is not abnormal in young dogs and proper training coupled with patience usually helps to overcome it. They then, during this period, have the annoying habit of putting everything in their mouth and ingesting inappropriate things : pieces of toys, wood, soil, pieces of paper/tissues, excrement, etc.… Dogs often like to eat non edible objects and sometimes even their own poop( which is called coprophagia in dogs) The Causes Of Pica in Dogsįirst of all, it is important to know that during their growth, puppies, like children, go through a phase of development called the oral phase, during which they discover the world with their mouth. For more information on this specific condition, please see our dedicated health sheet: coprophagia in dogs. When a dog ingests excrement, this is also a particular form of pica called coprophagia.

Pica is an abnormal eating behavior that consists of ingesting non-nutritive substances that are not logically intended to be eaten.
