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

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.

As a veterinarian, I’ve found that pet owners take seriously the responsibility of ensuring their dogs live healthy, happy lives. They worry about making sure their dog gets enough exercise, receives regular wellness checks and receives balanced nutrition that gives them energy to run and play.
What some people don’t realize is that owning and caring a dog can improve the owner’s health as well. Spending quality time with your dog and providing them with quality nutrition is good for the dog and can help ease stress and anxiety levels for you. Studies have shown that owning a pet can decrease blood pressure, cholesterol levels and triglyceride levels — which is great news for your heart health.
In short, when your dog is getting the best care, proper exercise, nutrition and love, they can enjoy a long and healthy life. And that can ultimately make you healthier, too!
Many owners see their dog as part of the family, and that sometimes means they will feed their dog like they feed themselves. For example, some people may choose low-carb or gluten-free diets for themselves and do the same for their pets. However, while this instinct comes from a place of love, many owners don’t realize that their dog’s dietary needs differ from their own.
Take grains for example. As a veterinarian, it’s important for me to note that grains are good for your dog. Yes, you read that right — they’re good!
A very small percentage of dogs may have a food sensitivity that requires a special grain-free diet or a dog food without a certain protein. However, this is not necessary for the vast majority of dogs. Most dogs benefit from a complete, balanced diet with healthy grains, high-quality proteins and essential vitamins and minerals.
Here’s why: Grains are a good source of carbohydrates that provide healthy energy. Some grains, like rice and wheat, provide “quick” energy, while other grains, like barley and sorghum, take longer to convert to energy. A combination of these different grains can offer a time-released energy source that helps dogs sustain energy. The whole grains in IAMS dog food are a beneficial mix, as they supply steady energy.
In addition to the grains you’ll find in IAMS food, you’ll also find high-quality proteins, like chicken and lamb, as well as essential nutrients needed to help support heart health. Together, this combination will give your dog a steady source of energy to be active on walks, runs, hikes or play sessions around the house.
For your dog to be healthy and happy, be sure you feed them a well-balanced diet and allow them enough exercise time. In return, you’ll get unconditional love, plenty of sweet doggy snuggles and maybe even more exercise — just a few of the ways you and your dog are joined at the heart.
