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.

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.

Watch as Veterinarian Dr. Katy Nelson shares all the basics of building a positive relationship with a puppy. You’ll learn everything from taking care of your puppy’s basic needs to socialization. When all is said and done you’ll learn how a happy puppy makes for a happy owner as well.
Hi, I'm Dr. Katy Nelson with IAMS, and today we're going to talk about how to take care of your puppy. First and foremost, you want to understand and meet your puppy's needs. Here they are in order of importance. Number one: basic health-- water, nutrition specifically formulated for puppies, and sleep. Also, immunizations and regular checkups are recommended. Number two: safety. As with small children, you need to keep your puppy in an environment that is safe for him. Puppies explore with their mouths, and they learn about different textures by gnawing. Also, chewing helps massage their gums. For your puppy's safety, keep things that he or she should not be chewing on out of reach. Number three: psychological. Your puppy's greatest psychological need is to be part of a group and be socialized with other dogs. However, to do this successfully, you need to be a guardian he can depend on. Once your puppy's basic needs are met, you want to understand the way he sees the world, so that you can build a strong relationship. Your puppy does not understand the world you live in, so you cannot expect him to. Two things you need to understand is that to them, everything is edible, and they will lunge at anything exciting—you, kids, guests, and other animals, until you train them not to. Praise him exuberantly to encourage the right behavior. Give him treats, pet him, play with him, and be stern to discourage the wrong behavior—ignore him, stop petting, or stop playing. Most importantly, be patient and consistent. Don't be harsh. Puppies have lots of energy, and it's healthy for them to use it. Periodically, helping your puppy release energy will minimize his urge to dig and chew on things. Spend time out in the yard making him run in short bursts. Go on walks or play fetch. Puppies are used to playing with their brothers and sisters. When they're separated, they're looking for their next playmate. Playing with your puppy will also make him more focused on you, improving your bond and making training easier. It teaches him new behaviors, self-control, and will help him gain self-confidence. Like play, socialization is also fundamental to raising your puppy. This is why socializing your puppy as soon as you bring him home is important for both of you. Socialization teaches your puppy to be calm in stimulating circumstances, and to obey when instructed. It also gets him used to being touched, handled, and even used to having hands and inedible things in and near his mouth, so that he behaves around other people, kids, and his veterinarian. Also, know that puppies are sensitive. They can read facial expressions and emotions. Be consistent about what things your puppy does that make you express happiness. Also, be careful not to give your puppy reason to think he's at blame for negative emotions you have from other areas of your life, like when you've had a bad day at work. Emotions are contagious. The happiest puppies tend to be in the most positive and loving households. I'm Dr. Katy Nelson with IAMS, and I hope that you found this helpful as you welcome your new addition to your family.
