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.

Is your dog really a finicky eater, or could it be something else? There are many factors to consider when you notice that your dog doesn't seem to be eating as usual.
If you're suspicious, take a closer look at exactly what he's eating each day. Does he get the occasional dog treat, or is someone sneaking him extra table scraps?
When you feed your dog a balanced, highly nutritious diet, nothing else is needed. In fact, extra treats can drastically alter your dog's normal intake of dog food. It's similar to the feeling you get after eating too much candy or potato chips. Are you interested in a full meal? Neither is your dog.
IAMS™ dog foods are nutritionally balanced and specifically formulated to meet the needs of dogs in all life stages, and with different lifestyles. There are dry, canned, and pouch varieties, plus options for senior or overweight pets, puppies, and dogs with reduced activity levels. Talk to your veterinarian or an IAMS Pet Care and Nutrition Center professional for advice on what's best for your dog.
Recommended feeding amounts are shown on every package. The guidelines are general suggestions for the amount of food you should feed your dog. Every dog is different and does not need the same amount of food. Your dog's activity level and his metabolic makeup are the determining factors. Start with the amount given in the feeding guidelines. Then, add or subtract food as you observe your dog's eating habits and weight.
Portion-Controlled Feeding: Divide the daily amount and feed at specific intervals. It is important to take away all leftover food after 15 to 20 minutes. This sets a pattern for your dog to follow. The portion-controlled feeding method is recommended for giant and large breeds as well as for overweight dogs. Portion control also works well for dogs with special needs.
Free-Choice Feeding: Feed the daily amount and let your dog eat at leisure. This method is recommended for use only with dry foods. Remember, dogs eat to meet their energy requirements. They quickly define their own daily portions when eating free-choice.
Water: Regardless of which food you choose to feed, your dog must have plenty of fresh, clean water. A good dog feeding tip is to place the water 3 to 5 feet from the food. This will help prevent your dog from gulping water and air in addition to food.
Routine: Dogs need it. Feeding at the same time and place every day establishes a comfortable eating pattern.
