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.

A puppy nibbling on your fingers may seem cute and harmless, but when he grows up, biting can become a hard habit to break. Join Expert Pet Trainer Kathy Santo as she explains the reasons puppies bite and what you can do to change their behavior.
Hi, I'm Kathy Santo with IAMS, and today we're going to discuss the dangers of allowing puppy biting, the importance of playing correctly, and how to stop the unwanted biting behavior.
It's normal and even cute when your puppy nibbles and lunges at your hands. Since your puppy has been exposed to only other puppies in the litter, who naturally play with biting and mouthing, it would make perfect sense why he would assume that playing with you wouldn't be different. But as puppies' teeth grow, and their bodies become stronger, what was once cute nibbling eventually turns into uncomfortable, or even dangerous, rough play and bites.
Since biting is an unacceptable type of play, it's important to teach your pup how to enjoy playing games with toys instead of your hand. Playing is a healthy, natural activity that helps build the bond between you and your puppy. This also affects your puppy's train ability-- sitting, waiting, learning tricks, not pulling on the leash, even to stop biting.
Before teaching your puppy not to bite, it's important to train your puppy to decrease bite pressure. Allow your puppy to begin mouthing and nibbling at your hand. When he bites down hard, yell 'ouch,' so he's startled and stops for a second. Continue allowing him to mouth your hand, making sure to speak up every time he bites too hard, so your puppy can learn your threshold for what is acceptable and what isn't.
Once your puppy understands your feedback about the strength of his bite, you can begin to reduce biting. The best way to teach your puppy not to bite is to redirect him to a toy or a chew bone. Simply give your dog a firm 'no,' and replace whatever he was biting with something he is allowed to chew.
If your puppy is three to six months old, there is a good chance he may be teething, so he might be trying to reduce discomfort by chewing. Try giving him an ice cube to chew on. It'll numb his gums and help alleviate the pain.
My favorite trick to get puppies to stop biting is to exaggerate, and pretend they've injured me, their friend. By pretending their nip actually hurt you, by pulling your hand away, yelling 'ouch,' and stop playing, you're replicating what other litter mates would do if another puppy were to cause them pain.
Managing and controlling puppy biting problems can be a major challenge for dog lovers. Puppy biting or nipping starts out as a bit of fun, but needs to be controlled quickly to avoid ongoing problems. Training your dog depends on a good relationship built on love and trust. It takes time to build a working partnership, and the more time and patience you have with your puppy from day one, the more obedient he'll be. Dogs want to please.
I'm Kathy Santo with IAMS, and I hope you found this as helpful as you welcome your new addition to your family.
