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.

Dogs hit maturity around 7 years of age (5 years for larger dogs). It's not uncommon for them to live as long as 15 years. As your pet enters his golden years, his activity level might slow down and common conditions such as arthritis, diabetes, and kidney disease may arise. “It is so more important to monitor the eating habits of older pets,” stresses Tom Carpenter, DVM, president of the American Animal Hospital Association. “Generally, older pets do not need as much protein, sodium, and phosphorus. But your veterinarian needs to address this for your individual pet,” he says, adding that semiannual vet visits are recommended for an older animal.
Some mature dogs are prone to obesity. To test whether your dog is at a healthy weight, move your hands along his sides. If you can feel his ribs (but don't see them), he's doing okay. But if you feel a fat covering, or you visibly notice a rounded abdomen, he might be overweight. Exercise is still important for a senior dog, and if he's gained weight, you want to look for a low-fat weight-control food that contains vitamin-rich fish oils (IAMS™ ProActive Health™ Mature Adult is one good choice).
Other mature pets can become finicky eaters and lose weight as they age. 'Very old pets may actually need a more calorie-dense diet,' Carpenter says. Older dogs can lose their sense of smell and have a harder time chewing their food. To make mature dog food easier to eat, you can top their dry food with room-temperature wet food.
If your dog is gaining or losing a lot of weight, slightly decrease or increase his daily feedings. A sudden change in weight or appetite might be a sign of disease, so you should check with your vet. Water is also essential. 'Older pets are at a higher risk of dehydration,' Carpenter says. Provide a clean bowl with fresh water at all times.
