Yet this behavior—gross as it seems—affects roughly one in four dogs at some point in their lives. Understanding what drives this habit and how to address it makes the difference between months of frustration and a quick resolution
Coprophagia in dogs refers to the consumption of feces, whether their own, another dog's, or that of different species like cats, rabbits, or deer. The term comes from Greek roots: "copros" (feces) and "phagia" (eating).
A 2012 study presented at the American Veterinary Society of Animal Behavior conference found that 16% of dogs are "serious" stool eaters, consuming feces at least five times, while 24% have been observed eating poop at least once. The behavior shows up more frequently in multi-dog households—likely because there's simply more opportunity.
Dogs typically fall into three categories: those who eat their own stool (autocoprophagia), those who consume other dogs' waste (allocoprophagia), and those who target feces from different species. Cat poop proves particularly attractive to many dogs, probably due to the high protein content in feline diets. Rabbit droppings and deer pellets also rank high on the "appeal" list for reasons that remain somewhat mysterious to researchers.
The behavior appears equally across male and female dogs, though intact males show slightly lowe...
