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.

Looking for the perfect dog food to pair with their side of sod slaw? IAMS has the answer for that, too.

We’re not talking about the “Sit. Shake.” kind of shake. Nor the fun way they shake off water starting from their nose all the way to the end of their tail. (FYI, dogs can shake off 70% of the water on their fur in just four seconds!)
No, we’re talking about that full-body trembling you’ve likely seen your pooch do from time to time. Why do they do it? And is it something you should be worried about? Let’s shake a leg and find out.
A majority of dog owners in an IAMS™ survey* (64%) think dogs shake because they’re cold. Other top responses were because they’re scared (57%) or anxious (54%).
High-fives all around because it turns out there are a number of reasons dogs shake, and all those are possible correct answers.

Just like their owners, dogs will often shiver when cold.
Opens a new windowDr. Tammie King, Applied Behavior Technical Leader at Waltham Petcare Science Institute, says: “Dogs shiver in response to falling temperatures. Dogs with short or no hair are especially susceptible. You should get them warm, put coats on them or bring them inside.” Same goes for you.

“Shaking is a response to epinephrine or adrenaline secretion — a sign of anxiety where the dog is on high alert,” says
Opens a new windowJames Serpell, B.S., Ph.D., Professor of Humane Ethics & Animal Welfare at the University of Pennsylvania School of Veterinary Medicine. You may notice this when you’re at the vet or there’s a situation where they feel threatened. Dr. Serpell also offers a way to help in some cases: “Identify what’s triggering the behavior. Provide them comfort. Going forward, you can gradually desensitize your pet to the thing it’s afraid of.” Unless it’s clowns. Those are always scary.
Trembling can also be a sign of serious issues like injury, poisoning or kidney disease. Opens a new windowDr. Jo Gale, BVetMed CertLAS MRCVS, Senior Manager, Global Science Advocacy at Waltham Petcare Science Institute urges pet owners to be vigilant: “If a pet is unwell in another way, they could be trembling.” If their shaking is accompanied by symptoms like diarrhea, limping or vomiting, you should consult your vet straight away.
