As dog owners, we all know that our furry companions can sometimes behave in ways that leave us wondering what’s going on. One common concern that many dog owners experience is when their dog starts shaking or trembling. While it’s easy to jump to conclusions or feel alarmed, shaking in dogs can have many different causes, some of which are completely normal, while others might require medical attention.
If your dog is shaking, it’s important to understand the potential reasons behind this behavior. In this article, we’ll explore why dogs shake, how to tell when it’s a sign of something serious, and what you can do to help your dog feel better.
1. Cold or Chilly Weather
One of the most common and harmless reasons a dog might shake is because they’re cold. Just like humans, dogs can get chilly when the temperature drops, and shaking is their body’s natural way of trying to warm up. Smaller dogs, dogs with short coats, or older dogs may be especially sensitive to cold temperatures.
If your dog is shaking and it’s chilly outside, try bringing them inside to a warm area, or provide them with a dog sweater or blanket to help keep them warm. You might also want to limit their time outside during cold weather to prevent them from getting too cold.
2. Excitement or Anxiety
Dogs can shake when they’re excited, nervous, or anxious. If your dog starts trembling before a walk, when they see their favorite toy, or when you’re about to leave the house, the shaking may be a sign of excitement. Some dogs also shake when they’re anticipating something they enjoy, such as mealtime or going for a ride in the car.
Similarly, anxiety or fear can cause shaking. Many dogs experience anxiety in stressful situations, such as during thunderstorms, fireworks, or trips to the vet. If you notice your dog shaking in situations where they seem uneasy, it’s likely due to anxiety.
3. Pain or Injury
Shaking can also be a sign that your dog is in pain. Dogs can be very good at hiding discomfort, so shaking might be one of the few ways they can communicate that something is wrong. If your dog is trembling, it could indicate that they’ve injured themselves or are experiencing pain from conditions like arthritis, hip dysplasia, or other musculoskeletal issues.
If the shaking is accompanied by other signs of pain, such as limping, whining, or difficulty moving, it’s important to take your dog to the vet for a thorough examination. Pain management and proper treatment can help ease their discomfort and stop the shaking.
4. Medical Conditions
There are a variety of medical conditions that can cause a dog to shake. Some of these conditions may require immediate attention from a veterinarian, while others can be managed with proper care. Some common medical causes of shaking in dogs include:
- Canine Distemper: This viral infection affects the nervous system and can cause shaking or tremors. Other symptoms include fever, coughing, and a lack of appetite. If your dog is exhibiting symptoms of distemper, you should seek veterinary care right away.
- Hypoglycemia (Low Blood Sugar): Small breeds or puppies are more prone to low blood sugar, which can cause shaking or trembling. If your dog is shaking and appears weak or lethargic, it could be due to hypoglycemia. Providing them with a small amount of food or glucose can help, but it’s important to consult with a vet for proper diagnosis and treatment.
- Seizures: Dogs who experience seizures may shake or tremble during or after the episode. If your dog is shaking in a rhythmic manner or loses consciousness during the shaking, they could be having a seizure. Seizures require immediate veterinary care to diagnose and manage.
- Toxin Exposure: Ingesting toxins, such as certain foods (chocolate, grapes, etc.), chemicals, or plants, can lead to shaking, among other symptoms like vomiting or diarrhea. If you suspect your dog has ingested something toxic, contact your veterinarian or an emergency animal poison control hotline right away.
- Old Age or Neurological Disorders: As dogs age, they may develop neurological issues that cause tremors or shaking. This is particularly common in senior dogs and can include conditions like cerebellar ataxia or generalized tremor syndrome (GTS). If your senior dog is shaking but doesn’t seem to be in pain, it’s a good idea to have them evaluated by a vet to rule out any neurological problems.
5. Nausea or Upset Stomach
Just like humans, dogs can experience nausea or stomach upset. If your dog is shaking after eating, it could be due to digestive issues such as gas, bloating, or an upset stomach. Nausea can also result from motion sickness, particularly during car rides. Dogs can get anxious or nervous about car travel, which can lead to shaking and drooling.
If the shaking is accompanied by other signs of nausea, such as excessive drooling, vomiting, or lack of appetite, it’s important to monitor your dog and consult with your veterinarian. In some cases, mild stomach issues can be treated with dietary changes or medication, but a vet should determine the underlying cause.
6. Fear or Phobia
Dogs may shake due to fear or phobia in certain situations. Common triggers include thunderstorms, fireworks, loud noises, or unfamiliar environments. Fear-based shaking is often accompanied by other signs of anxiety, such as panting, whining, or hiding.
If your dog is shaking due to fear or a phobia, there are several things you can try to help them feel more secure. Providing a safe space, like a quiet room or crate, can help reduce their anxiety. Additionally, calming aids such as anxiety wraps, pheromone diffusers, or medication prescribed by your vet may also be useful.
7. Hormonal Imbalance
Hormonal imbalances, such as those caused by issues with the thyroid or adrenal glands, can also cause shaking in dogs. Conditions like hypothyroidism (low thyroid function) or Cushing’s disease (overproduction of cortisol) can affect your dog’s metabolism and lead to symptoms like shaking, weight changes, and changes in appetite or behavior.
If you notice persistent shaking along with other unusual signs, it’s worth discussing your dog’s symptoms with your vet. Hormonal imbalances are treatable with medication or other therapies, so early diagnosis is key to managing these conditions.
8. Emotional Reactions
Just like humans, dogs can experience emotional responses that cause them to shake. This can happen when they’re in a situation that makes them feel overwhelmed, confused, or scared. For example, a dog might shake if they are separated from their owner or placed in an unfamiliar environment.
In these cases, the shaking usually goes away once the stressful situation is resolved. However, if your dog’s emotional reactions are frequent or intense, it may be helpful to work with a professional dog trainer or behaviorist to help manage anxiety and stress.
What Should You Do If Your Dog Is Shaking?
If your dog is shaking, it’s important to first assess the situation and determine the likely cause. If your dog is cold, bring them inside or offer them a blanket or sweater. If they’re excited, try to calm them down with some soothing words or a relaxing activity. However, if your dog’s shaking is persistent, severe, or accompanied by other concerning symptoms, it’s always best to consult with a veterinarian.
Your vet can perform a thorough examination to rule out any underlying medical conditions, and they can recommend a course of action to help your dog feel better. Depending on the cause, treatment may involve medication, dietary changes, behavior modification, or lifestyle adjustments.
Conclusion
Shaking in dogs can be caused by a variety of factors, from something as simple as being cold or excited, to more serious health concerns like injury, illness, or anxiety. While some causes of shaking are harmless and temporary, others may require medical attention. As a dog owner, it’s important to observe your dog’s behavior, take note of any other symptoms, and consult with a veterinarian if you have any concerns. By understanding the reasons behind your dog’s shaking, you can take the appropriate steps to ensure their comfort and well-being.
