Why Is My Puppy Shaking?

Adopting a little puppy can be one of the most uplifting experiences ever. But once reality sets in, and you realize you’re responsible for the safety and health of this little, helpless creature, that can make any pet parent a little neurotic about everything from their weight to their behavior. And if your puppy seems to be trembling a lot, that can be especially unsettling for both you and your dog.

Rest assured, occasional shaking can be normal for puppies — due to excitement, cold, or fear. However, if tremors or shaking persist, this could be a sign of shaking puppy syndrome (an inherited health condition that affects the nervous system). If that’s the case, there’s no need to panic, but you will need to visit your vet. Below is everything you need to know about shaking puppy syndrome, from symptoms to treatment.

What is shaking puppy syndrome?

Shaking puppy syndrome is another name for a group of neurological disorders affecting puppies’ nervous systems. The most common among them is hypomyelination, which refers to a thinning of the myelin (a sort of protective casing) around the nerves. The condition may be referred to as shaking puppy syndrome/hypomyelination. It is linked to tremors and motor control issues, and has been linked to genetic mutations in certain breeds, most notably Weimaraners and Springer Spaniels. 

Is shaking puppy syndrome dangerous? 

While there is no cure for shaking puppy syndrome, puppies with milder forms can improve with age and medical care. Tremors may lessen, and motor control can improve as they grow. In more severe cases, though, shaking puppy syndrome can be dangerous if left untreated. In either case, tremors and motor control issues can impact a puppy’s quality of life, making daily activities like walking and eating a challenge. 

Luckily, early diagnosis by a veterinarian can help mitigate symptoms and improve your puppy’s prognosis. Treatments may include medications to reduce tremors and supportive care to ensure your puppy can grow and develop as normally as possible. In more severe cases, the condition may require lifelong management. But working closely with your veterinarian can help provide a good quality of life for your growing pup. 

Symptoms of shaking puppy syndrome 

If you’ve just adopted a puppy, monitor their health and development in the early stages to watch for any illness or issues. Recognizing the symptoms of shaking puppy syndrome early can make a significant difference in managing the condition and ensuring your puppy’s well-being. Here are some key symptoms to watch for. 

• Tremors: Look for involuntary shaking that worsens with excitement or stress.

• Muscle weakness: Notice if the puppy has difficulty standing or walking steadily.

• Poor coordination: Watch for unsteady movements or stumbling when the puppy tries to move.

• Head bobbing: Observe the puppy for rhythmic, involuntary movements of the head.

• Difficulty eating: Monitor the puppy if they struggle to chew or swallow food.

• Frequent falls: Keep an eye on the puppy for frequent falls or a lack of balance.

• Delayed growth: Check if the puppy’s physical development appears slower than typical for their age.

Shaking puppy syndrome prognosis

Outcomes for shaking puppy syndrome vary based on the severity of the condition, and sometimes based on your dog’s specific breed. With early diagnosis and proper medical care, many puppies can go on to have a normal lifespan with a relatively good quality of life. 

Regular vet visits will be important, and your vet will likely perform neurological exams to monitor your dog’s development. Long-term treatments may include medications to manage tremors, physical therapy, and supportive care for nutrition and growth. Your veterinary team should take a proactive approach, including frequent check-ups and adjustments to the plan as your puppy grows. 

Treating shaking puppy syndrome

Treatment for shaking puppy syndrome should be tailored to the severity of your dog’s condition and may involve supportive care and environmental management. Providing a calm and stable environment, ensuring proper nutrition, and monitoring your puppy’s development are all key. Mild tremors will often improve as your puppy grows, and in some cases, they may even outgrow shaking puppy syndrome entirely. Just make sure to check in with your vet regularly. 

For moderate to severe cases, medical intervention is more likely required. Veterinarians may prescribe medications to manage shaking and improve motor control. They may also recommend physical therapy, which can help strengthen muscles and improve coordination for better control. Occasionally, severe cases require neurological support or specialized diets. Again, frequent vet visits are important to help adjust strategies throughout your dog’s life. With treatment, even dogs with more severe symptoms can experience a good quality of life. (If treatment costs start to add up, be sure to check out options for financial assistance with vet care.) 

Other reasons your puppy may be shaking

While shaking puppy syndrome can be a serious condition, it’s important to note that not all instances of shaking in puppies indicate a severe problem. Shaking can sometimes be a natural response to fear, overstimulation, or even excitement. For example, puppies often tremble when they’re overly excited to see their parents, or when they’re nervous in new environments. 

It’s always a good idea to consult your veterinarian if you notice frequent or intense shaking, but occasional trembling can be a normal part of a puppy’s behavior. Understanding the other potential causes can help you distinguish between harmless behavior and serious symptoms. Taking the right steps to prepare for a new puppy can also help mitigate these issues. 

Breed

Certain breeds are more prone to shaking due to genetic predispositions. For instance, small breeds like Chihuahuas and Miniature Pinschers are known for shaking more frequently, which can be a normal part of their behavior. 

Stress and anxiety

Puppies may shake when they’re stressed or have separation anxiety. In these cases, identifying and minimizing stressors can help reduce shaking. Another tip for puppy care: positive reinforcement, which can help your puppy overcome the stress of new experiences. 

Cold temperatures

Puppies can be sensitive to cold temperatures and may shake to generate body heat (just like the way humans shiver in chilly weather). Ensure your puppy is warm and comfortable, especially when they’re very young and when the months grow colder. 

Excitement or overstimulation

Puppies tend to get very excited during playtime or when greeting people. The excitement may cause them to tremble with energy, but this type of shaking is typically harmless. It usually subsides as your puppy grows and calms down with age. 

Commonly asked questions

Does shaking puppy syndrome go away? 

Yes, it is possible for shaking syndrome to go away, but that is not always the case. With early diagnosis and proper treatment, the issue can improve as a puppy grows. Still, while some puppies may outgrow the condition, others may continue to experience symptoms into adulthood, requiring ongoing veterinary care and management.

Why is my puppy shaking in their sleep? 

Puppies often shake or twitch in their sleep due to normal dreaming and REM (Rapid Eye Movement) sleep cycles. This type of shaking is typically harmless and reflects healthy brain activity during sleep.

Why is my puppy shaking and throwing up? 

Shaking and vomiting in puppies can indicate a range of issues, from mild digestive upset to more serious conditions like poisoning or infections. It’s important to consult a veterinarian promptly to determine the cause and receive appropriate treatment.

Is there a shaking puppy syndrome test? 

The only way to diagnose shaking puppy syndrome is through DNA testing. Luckily, this has become more readily available and affordable over the last several years. You can speak with your veterinarian further about the proper testing required.
