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.

Dogs use a range of sounds to communicate with us and each other. Just as important is the body language they use to tell us how they feel or what they need. How well do you know your pooch’s unspoken cues? Read on to find out.
Dogs often stare at their owners because they love them. They want to make sure you’re okay or find clues for what you’ll do next — like making sure you’re not going for a car ride without them.
We love it when dogs do this, too, which has led to this trait being even more prominent.
Opens a new windowDr. James Serpell, BSc, PhD, Professor of Humane Ethics & Animal Welfare at University of Pennsylvania School of Veterinary Medicine, explains: “We've selected dogs for this behavior. Humans love that dogs look up at them in admiration, intense loyalty. One frequent observation researchers have made is that people who handle wild dogs ... they don't look their handlers in the eye like domesticated dogs do.”
Dogs have great hearing. High-frequency sounds that humans can’t hear are especially interesting to them. Head-tilting helps them track down the source. Owners find these head tilts super cute and often reward this behavior, which, of course, makes them do it more.
Dogs yawn when they’re tired, but it’s also a possible sign they’re stressed, impatient or frustrated — like when they’re in the vet’s office, or when you won’t throw that ball you’re holding already!
In a recent IAMS poll,* 90% of dog owners said their pet sits or lays on their feet and 100% of dogs said they love their owners. Dogs are very social creatures and this is a way for them to connect and be close to you. Plus, it keeps your feet warm.
Often called “raised hackles,” dogs do this when they’re nervous, threatened or showing aggression. It’s an adaptation from their wild days of attempting to make themselves look bigger.
Opens a new window Dr. Tammie King, Applied Behavior Technical Leader at Waltham Petcare Science Institute, offered this insight to keep in mind: “What’s important when talking about a dog’s body language is to not take one thing in isolation. You’re at risk of misinterpreting what the dog is trying to say to you. Context is everything.”
So be sure to pay attention to what your dog isn’t saying to keep them healthy and happy. Serving them
