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.

You want to take your new puppy out for a stroll; now, all you need to do is train him to walk on a leash. Watch as Expert Pet Trainer Kathy Santo show you how to walk your new family member.
Hi, I'm Kathy Santo with IAMS, and today we're going to talk about how to leash train your puppy. Once your puppy is around eight weeks old, you can begin leash training. The first thing you'll need is a collar or harness that fits your puppy appropriately, never too lose or too tight. You should be able to fit two fingers between the collar and your puppy's neck. When deciding between using a collar or a harness, there are a few things to consider. Does your puppy have any respiratory issues? Does your puppy pull when being walked on leash? Use a harness or head halter if your puppy pulls on leash, or has respiratory problems. Before you can jump right into training, you'll need to get your puppy used to wearing a collar and having the added weight of a leash. The best thing to do is have him wear the collar or harness and leash around the house, so he becomes used to the feeling. Be sure to keep an eye on your puppy to make sure he doesn't get trapped, caught, or accidentally injured. If your puppy is noticeably struggling, or looks scared, start off with a shoelace, or a small piece of rope, so he can get used to dragging only a little something around. This will help him get used to the added presence and weight of a collar and leash. Now for walking on a leash. The leash should have some slack, because when you put pressure on a dog, their natural reflex is to move or pull in the opposite direction. If you find that your puppy is afraid of walking with the leash, try placing treats along the route you know you'll be walking, to give him the notion that good times are ahead. That way, he learns to focus on what's ahead of him with curiosity, and not fear. As you begin walking your puppy, you will notice that your pace will sometimes have to be faster than you expect to retain slack in the leash. The more you work with your puppy, the quicker you'll be able to train him to slow down, while maintaining the needed slack. As you walk around, begin incorporating specific commands for your puppy. Basic commands include sit, stay, and heel, or let's go. Do your best to remain consistent with your commands, and guide your puppy through the learning process. For example, when you say sit, guide your puppy to sit until the command is recognized by the puppy. When you say heel, make sure your puppy is obeying your command before you start walking again. When your puppy starts to move ahead too quickly, come to a complete stop and wait for him to cease pulling before going forward. Practice his stop and go, never allowing your puppy to dictate your pace. If your puppy continues to pull on his leash, ask him to change directions, while saying 'turn.' This will condition your puppy to always look for you for direction, instead of him feeling like he can dictate where the two of you go next. I also like to run backward, and then switch to a different direction. This gets your puppy excited about chasing you. Remember to reward your puppy when he does the right thing, so that he begins to understand what you're asking him for. If your puppy still isn't catching on, try upgrading your treats, practicing in an area with fewer distractions, or working on more basic commands. Leash training takes time and patience. Both you and your puppy may get frustrated during the learning process. Do your best to avoid tugging. It's not fair to correct them for something they don't understand. As your dog enters adolescence, and clearly knows the difference between right and wrong, it's OK to give a slight occasional tug on his leash, if he insists on being difficult. If you remain patient and consistent with your puppy, he'll be leash trained in no time. I'm Kathy Santo with IAMS, and I hope that you found this helpful as you welcome your new addition to your family.
