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.

Dogs love to chew on things. In fact, chewing is a natural canine behavior. Providing appropriate chew treats and chew toys can be rewarding for the dog and might prevent or eliminate possible destructive chewing behavior. Chewable treats/toys are designed to provide that important natural chewing activity that dogs love. If the chew treat/toy has other benefits, such as oral care, that's even better.
Make enjoying chew treats and chew toys a safe and healthy activity with these tips:
Tip #1: There is some risk of digestive-tract obstruction with any type of chew treat or chew toy. Safety is always a concern when a dog chews. Many natural objects, such as sticks, rocks, and bones, can get stuck in a dog’s throat or intestine. As a dog owner, you are ultimately responsible to monitor your dog closely to make certain that the chew treat is chewed well.
Tip #2: Chew treats and chew toys should be sized appropriately for your dog. In other words, your dog should not be given a chew treat/toy that could be swallowed whole. Packages should indicate the appropriate size dog for the chew treat/toy. If in doubt, ask your retailer or contact the manufacturer.
Tip #3: Observe your dog playing with the chew toy or eating the chew treat. With the chew treat, your dog should gnaw on it with the side teeth and swallow pieces of the edible chew. Because dogs don't have the same crushing molars that humans have, they will “slice” off pieces with the side teeth. Many dogs will hold the treat in their paws or simply move it from side to side in their mouth as they chew off small pieces.
Tip #4: If your dog has a history of ingesting foreign objects such as rocks, sticks, or toys, you might not want to give him or her chew treats/toys at all. Try edible biscuits, instead.
Tip #5: Watch for choking, excessive drooling, vomiting, poor appetite, lethargy, and abnormal bowel movements. If you notice any of these signs, seek veterinary care sooner rather than later!
Tip #6: When in doubt about what is appropriate for your dog, contact your veterinarian. He or she can offer professional advice.
