Introduction
Are you thining about Why Is My Dog Shaking? then your research ends here. While dogs can shake for the same reasons as humans, if your dog is shaking excessively or seemingly without reason, this can signal a problem that could potentially need veterinary care. In this article I will cover the most common reasons a dog shakes and provide some instructions on when to contact your veterinarian if you are concerned.
Cold and Temperature Sensitivity
Just like people, dogs can shiver when it is cold. However, they are more susceptible than most humans. Small dogs such as Chihuahuas and Toy Poodles lose body heat faster because they have less body mass. Puppies also feel the chill more as their bodies have not yet developed the ability to regulate their temperature. When dogs are curling up and shivering on very hard floors, or floors that are drafty and cold, it is reasonable to assume temperature is the first reason they are shivering.
In less severe cases, wrapping your dog in a soft blanket or providing a cozy bed in a warm part of your home usually stops the shaking. Especially on bitterly cold winter days, a sweater or dog coat can help, and make a huge difference. However, if shaking continues even in a warm environment, you will need to take other things into consideration.
Anxiety, Stress, and Excitement
Dogs often shiver and shake when they feel strong emotion. You likely have seen it when your dog is anticipating a car ride or has been startled by loud fireworks. Dogs can also tremble for excited reasons, like when you come home and they are excited to see you. The trembling and shaking result from a sudden adrenaline rush that prepares your dog’s body for “fight or flight.”
To alleviate possible anxiety in your dog, the first step is to create a peaceful situation. Your job is to speak calmly to your pet and offer a favorite toy or treat to distract his focus. With gradual exposure over a length of time and positive reinforcement, it is possible that he can lessen his fear‑based tremors. For dogs who shake in great anticipation-say for example, before meal time or taking a walk-a routine (based on your schedule) can build confidence and expectations can suppress excitement. Lastly, if the shaking is still a problem, or worse, contact a professionally certified trainer or behaviorist that specializes in canine anxiety.
Pain and Physical Discomfort
At times, shaking is a signal that your dog is in pain. Dogs generally shield pain, so shaking may be one of the few outward signs. If your dog is a senior with arthritis, then joints may hurt, especially after rest. Sudden injuries —such as a sprain or muscle strain— may cause immediate shaking.
Monitor your dog for stiff movements, limping, or hesitance to navigate stairs by noticing movements or behavior. You can feel the areas around joints gently for any heat or swelling. If there is pain, your veterinarian can determine the problem. Usually, treatment will include anti-inflammatories, joint supplements (e.g., glucosamine), or specific physical therapy. When you help your dog early, it reduces their discomfort but may minimize additional damage, and improve long-term outcome.
Nausea and Digestive Upset
An upset stomach can cause nausea in dogs. Similar to when you feel queasy and shake, dogs will shake when they’ve eaten something unpleasant. A dog can upset their digestive tract from diet changes, overindulging in rich foods, or from consuming a toxic substance. Depending on the dog, you may also observe drooling, lip-licking, or continuous yawning. These are also signs indicating that the dog could be feeling nauseous.
When your dog may have a mild episode of digestive upset, you may find success fasting them for a short while, then offering small amounts of boiled chicken and rice, which often helps get the stomach settled. Water is also important, give your dog plenty of fresh water and offer plain boiled rice available for when they are feeling hungry – this will also help with dehydration. If there is also vomiting, diarrhea or refusal to eat for greater than a day, don’t hesitate to go to the vet. Dehydration and electrolyte imbalance can develop rapidly and become serious, especially for smaller or older dogs.
Low Blood Sugar (Hypoglycemia)
Hypoglycemia or low blood sugar can affect young puppies and small breeds whose bodies use glucose quickly. Low blood sugar causes trembling and weakness, and the affected dogs may look confused, have disorientation or even collapse. Seizures can result if hypoglycemia is significant and no intervention takes place.
If you believe your dog is experiencing low blood sugar (if your dog is cold, shaking and somewhat lethargic) and you act quickly, it could save your dog’s life. You may gently rub a small amount of honey or corn syrup on the gums. Giving sugar is a quick way to get sugar into your dog’s system and it will often work very quickly to bring about relief, strength, and stop the shaking. You should then provide a light snack to eat and make a veterinary appointment as soon as possible. If your dog is still hypoglycemic, this is significant enough for your veterinarian to manage it professionally, and may indicate that there is an underlying metabolic disorder.
Exposure to Toxins and Poisoning
“Why is my dog shaking?” Sometimes the answer may be accidental toxin exposure. Common exposures are household cleaners, poisons in some plants—like lilies or azaleas—and human medications with which dogs should not come into contact. Some toxins, even in small quantities, can cause signs such as trembling, drooling, vomiting, and more severe neurological signs.
If you realize that your dog has consumed something toxic, such as chewed medication bottles, or half-eaten houseplants, you should take the remaining substance away, and note exactly what your dog ingested and how much. Right away, you should call your veterinarian, or a 24/7 pet poison hotline. It is very important to act fast in poisoning cases. The sooner treatment begins for your dog, the better the chances of a complete recovery with no permanent damage.
Neurological Conditions and Seizure Disorders
Some tremors are caused by disorders of the nervous system. Idiopathic epilepsy has a typical pattern of recurring seizures, with or without trembling prior to the seizure focus. Additionally, neurological shaking can occur due to infections, inflammation, or tumors in the brain. Signs that the shaking or tremors will be neurological include: an acute collapse, some partial loss of coordination or complete loss of coordination, any head tilt, or fall without reason.
When diagnosing these disorders, tests such as blood work, MRI or cerebrospinal fluid will likely be performed. While it may be terrifying to contemplate, plenty of neurological issues can be managed quite well. Anti-seizure medication, diet adjustments or targeted therapy are available which may help lessen the frequency or severity of your animal’s disorder. It is advisable to maintain an ongoing record of shaking episodes; including the time of day, length of time the shaking lasted and possible triggers. With such records available your veterinarian may be in a better position to identify patterns – enabling them to formulate a plan.
Age‑Related Tremor Syndromes
As dogs age, they can develop mild tremors, known as “old-dog tremor syndrome.” It occurs most often in small breed dogs older than ten. Tremors are usually fine, intermittent shake and occur in either the limbs or entire body for a short period of time.
If your senior dog is otherwise eating, playing, and acting normally with the intermittent tremors, you may not be overly worried. Still, mention the tremors at your next checkup so your veterinarian can assess for arthritis or neurological/conversion diseases, or common metabolic issues. In some instances, a lower dosage of muscle relaxants or nutritional supplements may increase comfort and reduce the tremors.
Fever, Infection, and Immune Responses
A fever is a sign that your dog’s body is fighting off an infection. If their temperature is increasing, they may also be shivering to generate more heat. Along with shivering, lethargy, decreased appetite, and warm ears are also signs of fever.
Use a pet thermometer and check your dog’s temperature, as a normal temperature is between 100.5°F and 102.5°F. If their temperature is greater than 103°F and they remain shaking, take them to the vet. If left untreated, fevers can cause dehydration and stress on organs. The vet will determine what type of infection is present (bacterial, viral, or parasitic) and prescribe antibiotics, antiviral medications, or other supportive treatment.
Genetic and Breed‑Related Disorders
Certain breeds are known to have inherited disorders that include tremors as part of the disorder. For example, a young “toy” breed can suffer from “shaking puppy syndrome,” which is characterized by full-body tremors that usually improve as the puppy matures. Some lines of bloodhounds and some other breeds have “episodic falling seizures” characterized by falling episodes often prompted by excitement and stress.
If your breed has the likelihood of having genetic disorders that cause tremors, you can speak to reputable breeders or canine geneticists regarding any screening tests. There are advantages to knowing your puppy has the potential for a genetic tremor disorder; it will help you set realistic expectations and potentially offer you some treatment or management options. Even more, breeders can use genetic information to try to reduce the occurrence of these conditions within the future litters.
Knowing When to Seek Help
Whether or not your dog’s shaking is serious is all about context and other signs. Some minor shivers in cold or after a bath are not worth a visit to a vet. On the other hand, recurrent or sustained shaking for greater than a few minutes does warrant a follow-up. Collapsing, inability to control seizures, difficulty breathing, an abnormally bloated abdomen, and exhibiting severe pain are all emergencies.
If you are still in doubt, always trust your instincts. If the cause of shaking was not serious, it is better to take your dog to the vet than wish you did earlier if the reason is serious. Most veterinary clinics have after-hours advice lines or emergency treatments for when you cannot wait until the morning.
Preparing for the Veterinary Visit
When you visit the clinic, be as prepared as possible with information. Write down when the shaking episodes occurred and how long they lasted. Try to remember any new activity that occurred before the shaking episodes (a new type of treat, a stressful car ride, a recent cold snap). Write down everything your dog was eating, any medications, supplements, and any possible toxins your dog was exposed to.
The more detailed and organized information you can provide to the vet, the quicker the diagnosis can be made. If the veterinarian recommends tests, you may have to get blood work done to check the functioning of the organs, x‑rays to rule out possible orthopedic concern, or possibly even some type of specialized imaging if there are any neurological concerns. The more your veterinarian knows about your dog, before she sees it, the quicker she can narrow down the list of possible causes.
At‑Home Care and Comfort Measures
While you’re waiting for treatment recommendations from the professionals, you can help make your dog more comfortable and safe at home. Keep your dog in a quiet location, free from drafts in your house. Provide a soft bed area with some cushioning to prevent injury while trembling. Offer a few sips of water and do not force them to eat if they feel nauseous or are refusing food. Speak softly to them and stay close by so your dog knows they are not alone.
If your dog’s trembling is triggered by temperature changes, change the thermostat in the room or add an additional blanket. For anxiety-related tremors, consider gentle massage, or provide diversion through play. Do not punish your dog for trembling behavior. This will increase the stress in the situation and may make your dog’s trembling worse.
Long‑Term Management and Prevention
Once you and your veterinarian discover Why Is your Dog Shaking?, they can begin to develop a long-term plan. Pain due to arthritis is best managed through a regular schedule of joint supplements and exercise plans which do not lead to over-activity. Anxiety disorders are often managed through behavior modification and, in some instances, short courses of anti-anxiety medications.
Preventative measures against toxic exposure means dog-proofing your home by securing chemicals, medications, and toxic plants out of reach. A well-balanced diet, routine feedings, and a slow transition into new foods can create a good foundation for digestive health. Small, frequent meals can help regulate blood sugars for breeds that tend to hypoglycemia.
Routine wellness exams to give your veterinarian the opportunity to assess weight, joint health, organ function, and neurological status before the small problems turn into big problems. Consistency and diligence can go a long way in keeping your dog happy, healthy, and tremor-free.
Conclusion
Opening the door to discovering a dog’s needs happens by asking, “Why is my dog shaking?” Shaking can often come from benign reasons—cold, excitement, or mild nausea—and at other times can indicate more serious issues, like poisoning or neurologic disease. Understanding your dog’s general condition and recognizing patterns of behavior related to shaking, combined with a willingness to consult with your veterinarian when warranted, empowers you as your dog’s health and comfort advocate.
Keeping your dog warm, calm, and on a predictable routine prevents many harmless tremors from taking place. Also, having your dog promptly checked by a professional for pain, toxin exposure, or systemic illness, will help your dog continue to lead a happy and full life. When you next see those tremors, you will at least be prepared to decide whether your dog just needs a blanket… or a trip to the vet.
