Like any companion or roommate, dogs — for all their love and cuteness—have habits we just don’t understand. One question dog owners often ask their pets: “Why? Why would you eat poop?”

When we polled* dog owners recently, most thought it was because a dog is lacking nutrients (49%), they’re anxious (43%) or they just think it tastes good (40%).
Dogs are significantly more likely to eat the droppings of another species (e.g., horses, rabbits) than their own.
We held our noses and got to the bottom of the issue with the help of some experts.
While those in our poll thought this was the number-one reason for the behavior, it has actually never been proven. “It’s a myth dogs eat poop because they’re seeking nutrients they aren’t getting. There’s no evidence to back this,” says

According to
Opens a new windowDr. Tammie King, Applied Behavior Technical Leader at Waltham Petcare Science Institute, “It can occur where there is lack of environmental enrichment. You see this often in dogs who are kenneled and have a lack of opportunity to exhibit normal canine behavior.” So if you need another excuse to get out and play with your pooch, this is a good one.
Believe it or not, this is the main reason dogs eat poop. Dr. Jo Gale explains: “Dogs are scavengers by nature and use any opportunity to eat what they can, when they can. They consider it a ‘tasty snack.’” Dr. Tammie King adds that “[Dogs eating poop] is a learned behavior. They’ve done it, enjoyed it, and that behavior is repeated.”
We love our dogs so much that we’re willing to trust our best friends on this. Maybe we should come out with a line of doggie breath mints though. Hmm.

“Ingesting feces from any animal increases potential for ingesting parasites and pathogens,” cautions Opens a new windowDr. James Serpell BSc, Phd Professor of Humane Ethics & Animal Welfare at University of Pennsylvania School of Veterinary Medicine. He went on to say, “[It’s] not something humans should ignore, but it's not worth getting too excited about it.”
All the experts we consulted said that if your dog occasionally eats poop, it’s nothing to be overly alarmed by. Just keep an eye on the frequency and their overall health. And as always, make sure they’re getting a nutritious diet and plenty of exercise and attention. If you have any concerns contact your vet.
Despite dogs liking the taste of poop, we’re going to stick with the healthy range of more traditional flavors offered in all IAMS dog foods.

Oral care is a key component of your pet’s overall health: A smart regimen can help prevent the development of serious conditions. Keeping your pet’s teeth clean and bacteria-free results in more than just healthy teeth and fresh breath. With a little know-how and effort, you can protect your pet for a lifetime of companionship.
Tartar and gingivitis are the most common problems seen by veterinarians. The majority of dogs will develop these problems. Unchecked, these can lead to periodontitis and serious health concerns for your pet, up to and including, tooth loss and serious illness. But you can take action to control this and promote good oral health by incorporating the 3Ds: Daily Brushing, Dentistry. and Diet.
Daily brushing of your pet’s teeth will remove plaque and slow the development of tartar. When first beginning to brush, be gradual and make it a pleasant experience. Start by using your finger. Later, introduce a toothbrush. Be sure to praise and reassure your pet while brushing. Also, reward your pet afterward with play or a walk.
Talk with your veterinarian about annual or semiannual teeth cleaning—a dental prophylaxis or prophy for short. Teeth cleaning, performed by your veterinarian, is the only way to remove tartar.
Diet is important to good oral health. The mechanical, brushing action of dry, crunchy kibbles helps remove plaque and works to scrub teeth clean. Some diets also might include ingredients such as hexametaphosphate (HMP) that can help block tartar formation. Diet, daily brushing, and dentistry helps break the plaque-to- tartar cycle and optimize oral health.
