8 Reasons Why Your Dog Might Be Shaking?

Dogs shake for a variety of reasons. Sometimes it’s just normal behaviour, but other times it can be a sign of an underlying medical or behavioural issue. In this section, we’ll explore possible reasons why your dog may be shaking and what you can do about it.

1. Possible Medical Reasons

If your dog is shaking excessively or has started shaking suddenly, it could be a sign of an underlying medical condition. Here are some possible medical reasons why your dog may be shaking:

1. Pain or discomfort: If your dog is shaking and seems to be in pain, it could be a sign of an injury or illness. Dogs may also shake when they’re uncomfortable, such as when they have an upset stomach or bladder infection.

2. Neurological issues: Certain neurological conditions, such as seizures or tremors, can cause your dog to shake uncontrollably. If you suspect your dog is having a seizure, seek veterinary care immediately.

3. Hypoglycemia: Low blood sugar can cause shaking in dogs, especially in small or toy breeds. If your dog is shaking and seems lethargic or disoriented, it could be a sign of hypoglycemia.

If you suspect that your dog's shaking is down to a medical reason, such as those mentioned above, it's important to consult with a veterinarian as soon as possible.

2. Possible Behavioural Reasons

Not all dog shaking is caused by medical issues. Sometimes, dogs shake because of behavioural reasons. Here are some possible behavioural reasons why your dog may be shaking:

1. Anxiety or fear: Dogs may shake when they’re feeling anxious or scared. This could be due to loud noises, new environments, or separation anxiety.

2. Excitement: Dogs may also shake when they’re excited, such as when they see their favourite toy or when you come home from work.

3. Attention-seeking: Some dogs may shake to get your attention or to get you to play with them.

If you suspect your dog’s shaking is caused by a behavioural issue, it’s important to address the underlying cause. This may involve training or behaviour modification techniques, such as desensitisation or counter-conditioning.

3. Temperature

Shivering or shaking in dogs is often a natural response to temperature changes, particularly when they are cold. Smaller breeds, short-haired dogs, or elderly pets are more susceptible to cold-related shaking.

Key points to watch for:

- Cold weather: Dogs may shiver to generate body heat.

- Hypothermia risk: Prolonged exposure to cold can lead to serious health issues.

- Overheating: In hot conditions, panting and shaking together could signal heatstroke, which requires urgent care.

Ensure your dog is kept warm during cold weather and cool during heat to prevent temperature-related shaking.

4. Stress

Shaking is a common reaction to stress in dogs, as adrenaline is released in response to anxiety.

Common triggers include: 

- Thunderstorms or loud noises: Sudden loud sounds like fireworks can cause shaking.

- Separation anxiety: Being left alone for extended periods may trigger stress-related shaking.

- New environments or travel: Changes in routine, unfamiliar places, or car rides can lead to anxiety.

To help, create a calm environment, use calming aids like CBD, or consult a vet for stress management strategies if your dog frequently shakes in stressful situations.

5. Age & Arthritis

As dogs age, they become more prone to joint issues such as arthritis, which can cause shaking due to discomfort or pain.

Signs to look for include: 

- Joint stiffness: Difficulty moving, especially after resting or in cold weather.

- Shaking after walks: Increased shaking may occur after physical activity.

- General discomfort: Senior dogs may shake when experiencing ongoing joint pain.

Support your ageing dog by providing joint supplements, ensuring they have a comfortable and warm sleeping area, and seeking veterinary advice for arthritis management.

6. Ear Discomfort

Dogs frequently shake their heads or bodies due to ear discomfort, which is often caused by:

- Ear infections: Bacterial or yeast infections may cause inflammation, leading to head shaking and skin irritation.

- Ear mites: Parasites can irritate the ear canal, causing your dog to shake its head constantly.

- Foreign objects: Small debris or plant matter trapped in the ear can lead to frequent shaking.

Regular ear cleaning and prompt treatment for any signs of infection or irritation can help prevent further shaking and discomfort. If ear issues persist, seek veterinary care to avoid long-term damage.

7. Drying Off

Dogs instinctively shake to dry themselves off after being wet. This is a natural behaviour that helps remove excess water from their fur.

Key times when shaking might occur include:

- After baths: Dogs shake vigorously to shed water from their coats.

- Rain or swimming: Shaking helps remove water and regulate body temperature.

- Prevent matting: Shaking helps avoid tangles in wet fur, particularly in long-haired dogs.

To assist, gently towel dry your dog after they get wet, or use a dog-friendly blow dryer for extra drying in cooler environments.

8. Regulating Emotions

Dogs may shake as a way to regulate emotions, particularly after excitement or tension.

This behaviour is common in situations where:

- Playtime ends: After an intense play session, dogs may shake to release pent-up energy.

- Tension relief: After a stressful encounter, dogs may shake to calm their nervous system.

- Excitement: Shaking can occur after greeting someone or during anticipation. This type of shaking is generally harmless and can be a normal way for dogs to release emotional tension or return to a state of calm.

Should I be worried if my dog is shaking?

It's normal to be concerned if your dog is shaking persistently or if it’s accompanied by other symptoms like vomiting, lethargy, or pain. Occasional shaking can be normal, due to excitement or cold, but consistent shaking may indicate issues such as pain, anxiety, poisoning, or neurological disorders.

If the shaking is unusual or severe, it’s best to consult a vet to rule out serious health concerns and ensure your dog receives proper care. Immediate attention is needed if there are signs of distress, illness, or unexplained behavioural changes.

What to do if your dog is shaking: 4 Steps to consider

If your dog is shaking, there are several things you can do to help them feel more comfortable:

1. Provide a warm, comfortable environment

Dogs may shake if they are cold or uncomfortable. Ensure they have a warm, comfortable place to rest, and consider providing a blanket or bed to help them feel more secure.

2. Check for signs of illness or injury

Shaking can be a symptom of a more serious underlying condition. Check your dog for any signs of illness or injury, such as vomiting, diarrhoea, or limping. If you notice anything unusual, contact your vet immediately.

3. Offer food and water

Low blood sugar or dehydration can cause shaking in dogs. Offer your dog food and water to help keep them hydrated and nourished. If your dog is not eating or drinking, contact your vet.

4. Provide comfort and reassurance

Dogs may shake if they are anxious or stressed. Offer your dog comfort and reassurance by petting them or talking to them in a soothing voice. Avoid scolding or punishing your dog, as this can increase their anxiety.
