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.

Here's what you need to know about your dog’s health as he matures from 1 to 8 years:
Your dog is growing up. Louise Murray, DVM, director of the ASPCA's Bergh Memorial Animal Hospital in New York City and author of Vet Confidential (Ballantine, 2008), gives advice on how to keep your dog in tip-top shape.
Adult Dog Health: Preventive Health. Even if your dog appears fit, see your veterinarian once a year for a checkup. 'Most health problems are more readily and less expensively addressed if you catch them early,' Murray says. What's more, your vet can detect problems that you might miss. You can also stay up to date on vaccination boosters.
Adult Dog Health: Flea, Tick, and Heartworm Medicines. Continue to use preventive medicines. Talk to your veterinarian if you've moved or if your lifestyle has changed to make sure you are using the products best suited for your dog.
Adult Dog Health: Diet. Your pet needs the right food for optimal health. Check with your vet about adjusting the type and amount of food that your dog eats.
Adult Dog Health: Dental Health. If you haven't done so already, get in the habit of cleaning your dog's teeth daily. 'Animals who get gingivitis or inflammation of the gums can end up with problems of the kidneys and the heart,' Murray explains. Get your dog accustomed to having your fingers and hands around her mouth. At the pet store, you'll find dog toothbrushes and finger brushes as well as dog toothpaste.
Adult Dog Health: Weight Gain/Loss. When your dog steps on the scale at her annual visit, weight gain (rather than loss) is more likely to be the problem. Meals usually are not the culprit. It's the things, such as biscuits and human food, she gets in between. 'It all adds up,' Murray says. As your pet gets older, she becomes less active, which can contribute to weight gain and a host of other problems (diabetes, arthritis, and breathing trouble, for instance). But there's another reason to keep an eye on the scale: Weight loss might signal an underlying health problem.
