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.

Obesity is a common problem in dogs, but you can help your pet lose weight. Identifying the causes and following a total weight-management program can result in controlled weight loss and maintenance. A total weight-management program includes evaluating the animal, educating the pet owner, modifying behaviors, and tailoring the program to individual situations.
Obesity is defined as an increase in body weight, beyond the limitation of skeletal and physical requirements, resulting from an accumulation of excess body fat.
Obesity is caused when caloric intake exceeds caloric expenditure. This simply means that a dog eats more energy (calories) than it uses and stores the excess energy as fat.
There are many factors that can contribute to obesity:
Fat
Fiber and Fatty Acids
Carbohydrates and Special Ingredients
In addition, a diet that contains L-carnitine can help dogs metabolize fat. L-carnitine is a vitamin-like compound that helps burn fat.
A total weight-management program can lead to successful weight reduction in the obese dog. Complete evaluation by the veterinarian is always recommended, and owner compliance is essential to success.
IAMS™ and professional veterinary products provide optimum nutrition for animals that can benefit from a weight-management program.
