Why is my dog shaking 

As a dog owner, you’ve probably noticed your dog shaking from time to time. While occasional shaking or trembling can be normal, it can also be a sign of an underlying health issue. If your dog’s shaking seems persistent or unusual, it’s important to understand why it might be happening and whether you need to be concerned. 

Common Reasons Why Dogs Shake 

Dogs can shake or tremble for a variety of reasons. Some causes are harmless, while others may require medical attention. Understanding the context and other symptoms can help you determine whether the shaking is a normal response or something more serious. 

• Fear or Anxiety 

One of the most common causes of shaking in dogs is fear or anxiety. Dogs can become nervous or stressed for various reasons, such as loud noises (like thunderstorms or fireworks), being left alone, visiting the vet, or encountering unfamiliar environments. Shaking in these situations is typically temporary and should subside once the stressor is removed. 

• Cold or Temperature Sensitivity 

If your dog is shaking and its chilly outside, this could be a normal response to the cold. Smaller dogs, dogs with thin coats, or senior dogs are more susceptible to temperature changes and may shake to generate body heat. Providing warmth, such as a dog sweater or blanket, can help. 

• Excitement or Anticipation 

Some dogs shake when they are excited or anticipating something enjoyable, such as a walk, a treat, or playtime. This type of shaking is usually temporary and is a result of the dog’s enthusiasm or heightened emotions. If your dog starts shaking before you pick up their leash or shake a treat bag, they are likely just expressing excitement. 

• Pain or Discomfort 

Shaking can also be a sign that your dog is in pain or discomfort. If your dog is experiencing injury, arthritis, or other physical discomforts, they may shake as a reaction. In such cases, shaking may be accompanied by other signs of distress, such as limping, whining, or reluctance to move. 

• Illness or Fever 

If your dog is shaking along with other symptoms like lethargy, loss of appetite, or vomiting, it could be a sign of illness or infection. 

• Neurological Disorders 

Certain neurological conditions can cause shaking or tremors in dogs. These conditions can affect the brain or nervous system and lead to abnormal muscle movements. Seizures, tremor syndromes, and other neurological disorders may cause shaking. If your dog’s shaking seems persistent or uncontrolled, it’s important to consult with a vet. 

• Low Blood Sugar (Hypoglycaemia) 

Low blood sugar, or hypoglycaemia, can cause shaking in dogs, particularly in puppies or small breed dogs. If your dog hasn’t eaten for a long period, or if they have a condition that affects blood sugar levels, shaking could be a sign that they need food.  

• Poisoning or Toxicity 

In some cases, shaking can be a sign of poisoning or exposure to toxic substances. Certain foods, plants, medications, and chemicals can be toxic to dogs and lead to symptoms like shaking, drooling, vomiting, or lethargy. If you suspect your dog has ingested something toxic, seek immediate veterinary attention. 

 

When Should You Worry About Shaking in Your Dog? 

While occasional shaking may not be a cause for concern, certain signs and circumstances may indicate that your dog needs medical attention. You should seek veterinary care if: 

• The shaking persists for more than a few hours or occurs frequently. 

• Your dog is shaking along with other signs of illness, such as vomiting, diarrhoea, loss of appetite, or lethargy. 

• You notice muscle twitching, or your dog is unable to control the shaking. 

• Your dog has experienced a recent injury or trauma. 

• The shaking is accompanied by changes in behaviour, such as aggression or confusion.
