You’re sitting with your dog and notice something strange. Their body is trembling. It’s subtle at first, but then the shaking becomes more noticeable. Maybe it’s in their legs, or their whole body has a slight shiver. They look at you with those familiar eyes, and suddenly you’re wondering if something is wrong.
If you’ve ever found yourself asking, “Why is my old dog shaking?”, you’re not alone. Many dog parents notice trembling or shivering in their pets as they age. Sometimes, it’s harmless. Other times, it’s a signal that your dog needs help. Understanding the difference can give you peace of mind and help your senior dog feel more comfortable.
In this guide, we’ll explore why shaking happens in older dogs, how to know if it’s serious, and how Ollie Fresh Dog Food can help support your pup through their golden years.
Shaking in senior dogs can be caused by a wide range of factors, from something as simple as feeling cold to more serious medical conditions that need a vet’s attention. As dogs age, their bodies go through changes that can make them more prone to trembling.
Some of the most common reasons include:
While occasional, mild shaking may not be a cause for alarm, ongoing or severe trembling should always be checked out by your vet. The sooner you find the root cause, the sooner your dog can get the right care.
Shaking in an older dog can have many possible triggers, and the cause is not always obvious at first glance. Understanding the most common reasons can help you narrow down what might be happening with your pup.
Arthritis, joint stiffness, dental pain, or other chronic conditions can cause trembling. You may notice the shaking is worse after activity or when your dog is trying to stand up after resting.
Senior dogs often have thinner coats and less muscle mass, which means they can get chilly faster. If you notice your dog shivering more in cooler weather or when lying on a cold floor, temperature could be the cause.
Trips to the vet, loud noises, or even changes in the home environment can make an older dog anxious. Anxiety often shows up physically through trembling, pacing, or panting.
As dogs age, they naturally lose muscle mass. This can lead to shaking in the legs when standing or walking, especially after exercise or long periods of rest.
More common in small breeds or dogs with diabetes, low blood sugar can cause sudden shaking, weakness, and even collapse if left untreated.
Senior dogs can develop nerve-related conditions, including canine cognitive dysfunction (similar to dementia in humans), tremor disorders, or degenerative nerve diseases.
Illness, spoiled food, or dietary changes can cause nausea. Shaking may be accompanied by drooling, lip licking, or a refusal to eat.
Kidney disease, Cushing’s disease, heart problems, or infections can sometimes cause shaking along with other symptoms like weight loss, changes in appetite, or fatigue.
How to Tell if the Shaking Is Serious
Not all shaking is an emergency, but there are signs that your dog’s trembling could be a symptom of a more urgent problem.
Call your vet right away if you notice:
If the shaking is mild, intermittent, and your dog seems otherwise happy and healthy, you can monitor them at home while making note of when it happens. But when in doubt, it’s always safer to have your vet evaluate the situation, especially with senior dogs.
When you notice your older dog trembling, your first reaction might be to panic. While it’s natural to feel concerned, staying calm will help you assess the situation and keep your dog comfortable.
Here’s what to do right away:
If you bring your senior dog to the vet for shaking, the first step will be gathering as much information as possible. Your vet will want to know when the shaking started, how often it happens, and what other changes you’ve noticed in your dog’s behavior or health.
Your vet may perform:
A clear diagnosis is the key to creating the right treatment plan. In many cases, the underlying cause can be managed successfully, improving your dog’s comfort and quality of life.
The treatment your vet recommends will depend entirely on what’s causing the shaking. In some cases, it’s as simple as managing discomfort. In others, it may involve addressing a chronic condition.
Common treatment approaches include:
In many cases, a combination of these treatments works best to keep your senior dog comfortable and minimize shaking.
