Understanding Normal Dog Shaking: When It's Just a Fact of Life
Many dogs tremble or shake, even when it’s not cold outside. Dog shaking can be just a normal fact of life for some pups. It could be a variety of reasons, and often, these are completely harmless. Let's explore some of the benign explanations for why your dog is trembling.
Cold
Just like humans, dogs shiver when they're cold. This is a physiological response where shivering makes the muscles relax and contract in rapid succession, which helps create heat that can warm the body. Smaller dogs, dogs with short hair, or older dogs tend to shake when they’re cold more easily. If you notice your dog shaking when temperatures drop, or if they’ve been exposed to cold water, it’s likely their body’s way of trying to get warm. Take your dog back inside as soon as you notice them shaking to prevent hypothermia. Providing a warm blanket, a cozy bed, or even a dog sweater can often resolve this type of shaking.
Excitement/Anticipation
Have you ever noticed your dog trembling with excitement when you grab the leash for a walk, or when you come home after a long day? This is a very common and normal form of dog shaking. Their bodies are simply overflowing with energy and anticipation, and shaking is one way they release it. This type of shaking is usually accompanied by other signs of happiness, like a wagging tail, playful barking, or jumping. It's nothing to worry about and is often endearing.
Small Dog Syndrome
Many dogs, especially small dogs, shake frequently. This is especially common in small dogs like Chihuahuas, Yorkshire Terriers, and Miniature Pinschers. While the exact reason isn't fully understood, it's often attributed to a higher metabolism, a more sensitive nervous system, or simply being more prone to feeling cold due to their smaller body mass. Sometimes, it's just a characteristic of their breed. For these dogs, shaking can be a normal part of their everyday behavior, though it's always wise to monitor for any changes or accompanying symptoms that might suggest a deeper issue.
Age
As dogs age, their muscles and nervous systems can weaken, leading to tremors, particularly in their legs. Older dogs may experience shaking due to muscle weakness, joint pain from conditions like arthritis, or even neurological changes associated with aging. This shaking might be more noticeable when they are standing or trying to get up. While this can be a normal part of the aging process, it's important to differentiate it from pain or other medical conditions. If you notice new or worsening shaking in an older dog, a vet visit is recommended to rule out treatable causes and ensure their comfort.
Behavioral & Emotional Causes of Dog Shaking
Beyond simple physiological responses, a dog's emotional state can also manifest as shaking. Often, shaking is a symptom of stress and can be a sign of anxiety, cold, fear, or pain. Dogs shake for various reasons, and their emotional well-being plays a significant role.
Fear and Anxiety
Fear and anxiety are common emotional triggers for dog shaking. This can be caused by a variety of factors: loud noises like fireworks or thunderstorms, new people or animals, a new environment, or even specific traumatic experiences. Dogs with motion sickness may shake in the car, and dogs with separation anxiety may shake in your absence. When a dog is fearful or anxious, their body releases stress hormones, leading to physical symptoms like trembling, panting, whining, or hiding. Recognizing these triggers and providing a safe, calm environment can help alleviate this type of shaking.
Stress
Stress, closely related to fear and anxiety, can also cause dogs to shake. Environmental stressors such as a change in routine, moving to a new home, or even just feeling overwhelmed by too much stimulation can lead to trembling. Dogs are sensitive creatures, and they can pick up on tension in their environment or from their owners. Observing your dog's overall demeanor and identifying potential stressors can help you address the root cause of their shaking. Removing any environmental stressors—potential stressors causing your dog to become anxious or overly excited could be new people or animals, a new environment, loud noises like fireworks, or strange objects—is a crucial first step.
Motion Sickness
Some dogs experience motion sickness when traveling in a car, which can cause them to shake or tremble. This is often accompanied by drooling, yawning, or vomiting. The shaking is a response to the nausea and discomfort they feel. To help, try to make car rides more comfortable, perhaps by using a pet carrier, ensuring proper ventilation, or even consulting your vet about anti-nausea medication for long journeys.
Attention Seeking
In some cases, shaking in dogs may be a behavioral issue related to seeking attention. If a dog learns that shaking elicits a comforting response or extra attention from their owner, they might start to use it as a learned behavior. This is more common in dogs that are highly intelligent and observant of human reactions. While it's important not to ignore a dog's distress, ensure you're not inadvertently reinforcing unwanted behaviors. Providing regular exercise, mental stimulation, and positive reinforcement for calm behavior can help address behavioral shaking in dogs.
When Shaking Signals Discomfort: Pain and Illness
While some reasons for dog shaking are benign, others warrant a little more attention. Dog shaking can be a warning sign that something is amiss, particularly if it's new, persistent, or accompanied by other symptoms. Learn why dogs shake, tremble, or shiver and what you can do to help them, especially when pain or illness is involved.
Pain
Dogs hide their pain well, which can make identifying the source a challenge for pet owners and veterinarians. If pain is the source of your dog’s shaking, you will likely also notice other signs, including limping, reluctance to move, changes in appetite, aggression when touched, or excessive licking of a particular area. Shaking can be a subtle indicator of discomfort, whether it's from an injury, arthritis, or an internal issue. If your dog is shaking and showing any other signs of pain, it’s best to take your dog to the vet.
Nausea/Gastrointestinal Upset
Dogs experiencing nausea or gastrointestinal upset may shake. This can be due to eating something they shouldn't have, an infection, or other digestive issues. The shaking might be accompanied by drooling, vomiting, diarrhea, loss of appetite, or lethargy. If your dog is shaking and appears unwell, especially with digestive symptoms, a vet visit is crucial to determine the cause and provide appropriate treatment.
Generalized Tremor Syndrome (Idiopathic Tremor Syndrome)
Also known as "White Shaker Dog Syndrome," this condition causes generalized tremors throughout the body. Most dogs are otherwise normal, but the tremors worsen over time until the dog receives treatment. Fortunately, the condition is not painful and doesn’t affect the dog’s consciousness. Although the cause of idiopathic tremor syndrome is unknown, it can be treated by suppressing the immune system with steroids. It's often seen in small, white-coated breeds like Maltese, West Highland White Terriers, and Samoyeds, but can affect any breed. If your vet suspects this, they will typically perform tests to rule out other conditions before diagnosing and treating it.
Serious Medical Conditions Causing Dog Shaking
Some of the explanations for why your dog is trembling are benign, whereas others warrant an emergency vet visit. It's important to rule out any underlying health issues if your dog is shaking regularly. Find out the common causes, such as excitement, fear, nausea, pain, poisoning, and more, but be especially vigilant for the following serious conditions.
Poisoning
Ingesting toxic substances is a serious cause of dog shaking. Many common household items, plants, and foods are poisonous to dogs, including chocolate, xylitol (artificial sweetener), certain medications, pesticides, and some plants. Symptoms of poisoning can vary widely but often include shaking, seizures, vomiting, diarrhea, disorientation, weakness, and collapse. If you suspect your dog has ingested something toxic, seek emergency veterinary care immediately. Time is critical in these situations.
Seizures and Neurological Disorders
Certain medical conditions, such as seizures or neurological disorders, can cause dogs to shake. Seizures can manifest in various ways, from full-body convulsions to more subtle tremors or twitching. Neurological disorders, like canine distemper, brain tumors, or inflammatory brain diseases, can also lead to involuntary muscle tremors or shaking. Dogs experiencing these imbalances might also seem weak, disoriented, or unusually lethargic. If your dog exhibits sudden, uncontrolled shaking, especially if accompanied by loss of consciousness, confusion, or unusual behavior, it’s an emergency that requires immediate veterinary attention.
Low Blood Sugar (Hypoglycemia)
Hypoglycemia, or low blood sugar, can cause shaking, weakness, disorientation, and even seizures in dogs. This is particularly common in young puppies, small breeds, or dogs with certain underlying health conditions like diabetes or liver disease. If you notice your dog shaking and suspect low blood sugar, offering a small amount of honey or Karo syrup can sometimes provide a temporary boost, but immediate veterinary care is essential to address the underlying cause.
Kidney Disease/Adrenal Issues
Underlying metabolic imbalances, such as those caused by kidney disease or adrenal gland disorders (like Addison's disease), can lead to muscle tremors or generalized shaking. These conditions affect the body's ability to regulate electrolytes and hormones, which can impact neurological and muscular function. Dogs with these conditions often show other symptoms like increased thirst and urination, lethargy, vomiting, or changes in appetite. A veterinarian can diagnose these conditions through blood tests and provide appropriate management.
Head Shaking: A Specific Concern
While much of the discussion around dog shaking focuses on generalized body tremors, head shaking is a distinct symptom that warrants specific attention. Dogs may shake their heads in response to pain or discomfort in other areas of the body, such as dental issues or neck pain. However, it is most commonly associated with ear problems. If your dog is shaking their head excessively or showing other signs of discomfort, it is best to have their ears examined by a veterinarian. Ear infections, ear mites, foreign objects in the ear canal, or even allergies can cause intense itching and discomfort, leading to vigorous head shaking. Persistent head shaking can also indicate a neurological issue or a vestibular disorder affecting balance. A vet can properly diagnose the cause and recommend treatment, which might include ear cleaning, medication, or further diagnostic tests.
Breeds Prone to Shaking
Some dog breeds are more prone to shaking than others. For example, small breeds like Chihuahuas and Yorkshire Terriers are well-known for their tendency to tremble, often without any underlying medical cause, as discussed in the "Small Dog Syndrome" section. Other breeds, like Doberman Pinschers, often exhibit a condition called "Doberman Wobbler Syndrome," which can involve tremors and an unsteady gait. While a breed predisposition doesn't mean shaking is always benign, it can help inform your observations and discussions with your veterinarian. Knowing your dog's breed-specific tendencies can help you understand what might be "normal" for them versus a sign of concern.
What to Do If Your Dog is Shaking: A Step-by-Step Guide
If you’re wondering why is my dog shaking, seeing a vet is key. They can help find out what’s wrong and how to help your dog. However, there are some immediate steps you can take:
Observe and Assess
The first step is to carefully observe your dog. Note when the shaking occurs (e.g., only when sleeping, when excited, or constantly), how long it lasts, and if it’s localized to one part of the body (like a leg) or generalized. Look for any other accompanying symptoms such as vomiting, diarrhea, lethargy, limping, changes in appetite or thirst, disorientation, or unusual vocalizations. The more information you can provide to your veterinarian, the better they can diagnose the issue. Dog shaking can be due to many health issues, like neurological problems, anxiety, or pain.
Remove Stressors
If the shaking appears to be behavioral or stress-related, try to remove any environmental stressors. This could mean moving your dog to a quiet room, turning off loud noises, or temporarily separating them from new people or animals. Providing a safe, comfortable space can often help calm an anxious or fearful dog. If your dog is shaking due to cold, take your dog back inside as soon as you notice them shaking to prevent hypothermia and provide warmth.
Provide Comfort
Offer reassurance in a calm, gentle manner. Speak softly, pet them if they respond positively, and ensure they have access to water and a comfortable resting spot. Avoid overreacting, as this can sometimes heighten a dog's anxiety. If the shaking is mild and your dog seems otherwise normal, sometimes just a bit of comfort and observation is all that's needed.
When to See a Veterinarian
While some shaking is normal, if your dog is shaking, here are some steps you can take, and when to seek professional help. The shaking may occur off and on, but if it keeps happening, it’s best to take your dog to the vet—especially if you notice any other symptoms. Below are the most common causes we see in our clinic, plus what you can do about them at home, but remember a vet is always the best resource for diagnosis. You should contact your veterinarian immediately if the shaking:
- Is sudden, severe, or persistent.
- Is accompanied by other concerning symptoms like vomiting, diarrhea, lethargy, disorientation, limping, pain, or changes in consciousness.
- Starts after a potential exposure to toxins or an injury.
- Worsens over time.
- Is unusual for your dog's normal behavior.
- If your dog is experiencing pain.
Some common medical conditions that make dogs shake include epilepsy, low blood sugar, and arthritis. Your veterinarian will perform a thorough physical examination, ask detailed questions about your dog's history and symptoms, and may recommend diagnostic tests such as blood work, urinalysis, X-rays, or neurological evaluations to determine the underlying cause.
Preventing Shaking: Proactive Measures
While not all causes of dog shaking can be prevented, proactive measures can significantly reduce the likelihood of certain types of tremors and improve your dog's overall well-being:
- Maintain a Comfortable Environment: Ensure your dog is always warm enough, especially small, short-haired, or older dogs. Provide cozy bedding and consider sweaters in cold weather.
- Manage Stress and Anxiety: Identify and minimize stressors. For noise phobias, create a safe den, use calming aids (like thunder shirts or diffusers), or consult a vet about medication. For separation anxiety, work on gradual desensitization or seek professional behavioral guidance. Providing regular exercise, mental stimulation, and positive reinforcement can help address behavioral shaking in dogs.
- Regular Veterinary Check-ups: Routine check-ups are crucial for early detection of medical conditions that can cause shaking, such as arthritis, kidney issues, or neurological problems.
- Balanced Diet: A nutritious diet supports overall health and can help prevent conditions like hypoglycemia. Ensure your dog has access to fresh water at all times.
- Safe Environment: Dog-proof your home to prevent access to toxic substances, which can cause severe shaking and other life-threatening symptoms.
- Adequate Exercise and Mental Stimulation: A well-exercised and mentally stimulated dog is generally happier and less prone to anxiety-related shaking.
