It seems  every dog parent’s nightmare is to see your pet chewing on an unknown something. You rush over and scream, “WHAT’S IN YOUR MOUTH?” and then it becomes a Samson and lion battle trying to open your dog’s mouth, only to find an old band aid, cotton pad, or something else equally random. But what really gets every dog parent grossed out is when you catch your dog snacking on poop! You search on Google and the results suggest that it might be because of stress or enzymes deficiencies, but these are all just guesses.

Even though eating poop isn’t technically harmful to dogs, some people are turned off so much that they want to give their pups away. It’s the poopy-breath and the following licking. Ugh. Yes, dogs will do gross things and no, that’s not a reason not to love them.

Our dogs seem to get themselves into everything – but why do they have to chew on everything?

Benjamin Hart, a vet and the director of the Center for Animal Behavior, and a team of researchers from the University of California surveyed almost 3000 dog owners about their dog’s poop eating or coprophagy habits. Research showed that there was no relation to age, dietary differences, or compulsive behaviors.

Results did yield the fact that 80% of poop-eating dogs preferred poop that was no more than two days old. So this led Hart and his team to theorize that this fresh poop habit goes back 15 000 years to wolves.
