In a recent IAMS poll of dog owners,* 69% said their dog eats grass. That’s quite a lot. Owners also have quite a lot of theories on why their dog is noshing on the lawn.

It’s not just modern-day canines that eat grass. It’s likely something that has been going on for thousands of dog years. According to
Opens a new windowDr. Tammie King, Applied Behavior Technical Leader at Waltham Petcare Science Institute, “It is actually normal canine behavior. It has to do with innate behavior from canine ancestors. Potentially a remnant behavior.”
Dr. King also shared this with us: “A lot of people think dogs eat grass when they’re feeling ill, but studies have shown that’s not necessarily true.”
But then why do dogs eat grass? To get to the (grass)root of this issue, we asked

'There's no one reason. They just like the taste, texture and feel of the grass.'
So it’s perfectly fine if your pooch decides to have an occasional grass snack. Who doesn’t crave a salad every now and then?
However …

If your dog is getting adequate nutrition, there’s no need to worry. But the experts we talked with asked dog owners to please keep in mind the following:
· Grass that’s been treated with weed killer or pesticides should be off the menu.
· If your dog is eating grass excessively or routinely vomiting from eating grass, consult your vet.

IAMS research has shown that some dog-food products are best formulated using a combination of carbohydrate sources. All IAMS dog foods are formulated precisely to meet the nutritional needs of your dog in his life stage. Such a combination offers optimal digestibility and helps maintain energy levels.
Our dog foods contain a variety of carbohydrate ingredients:
Barley: IAMS uses ground whole-grain barley that's cooked at high temperatures and finely ground in our dry dog-food formulas as part of our patented carbohydrate blend.
Corn: IAMS uses high-quality corn kernels that have been finely ground to break up the outside covering of each kernel, and then cooked at high temperatures to increase digestibility.
Grain sorghum: Also called milo, it is cracked, finely ground, and cooked before it is added to our dry dog foods. It is another carbohydrate source in our patented carbohydrate blend.
Rice flour: Our foods contain small kernels of white rice that have been separated from the larger kernels of milled rice, ground, and cooked at high temperatures to optimize digestibility.
Wheat: This is another high-quality carbohydrate source. In our biscuits, the wheat is an excellent, palatable carbohydrate source and adds a firm texture to the biscuit during the baking process.
Highly digestible diets are an important factor in the well-being of your dog. They deliver more essential nutrients more efficiently, so there is less waste.
Innovative and patented research by IAMS scientists has found that when the complex-carbohydrate sources grain sorghum and barley are used in a dog's diet, their breakdown is enhanced at another level.
These carbohydrate sources are all highly digestible, meaning your dog's body will still metabolize a high percentage of each for energy. What's unique about these grains is that they break down slowly and evenly, providing a stable source of energy.
The slow, even breakdown of grain sorghum, corn, and barley results in moderate, stable blood glucose levels after a meal. By minimizing swings in blood glucose, diets containing such a blend supply sustained energy. IAMS holds a patent on using grain sorghum and barley in a blend for dogs.
