There's no one answer for coprophagia">why dogs eat poop. The behavior, known as coprophagia, isn't unusual among healthy dogs. A snack may consist of the dog's own droppings or those of other animals, and many dogs like eating cat poop. Plus, there's what Canadian veterinarian Dr. Mary Machum highlights as a particular doggy delicacy: frozen feces.
"'Poopsicles' are a bit like horse manure, horse hoof trimmings and cat poop in that they all seem to be a bit like crack cocaine for a dog," Machum, a veterinarian at the Crestwood Veterinary Center in Edmonton, Alberta, told The Dodo.
Although many pups cease ingesting non-food items as they grow older, a few dogs eat feces well into their later years, according to the American Society for the Prevention of Cruelty to Animals. There are even reports of dogs who twist around to get the stuff fresh from the source. A mother dog, the ASPCA points out, can also encourage a young puppy to defecate by licking and then, like any good mom, will clean up the mess.
