Understanding Idiopathic Head Tremors in Dogs: How Daycare Can Help and What to Avoid

It can be distressing to witness your dog’s head shaking uncontrollably, especially when it happens without warning or obvious cause. One condition responsible for this puzzling behaviour is Idiopathic Head Tremors (IHT). While the term "idiopathic" simply means the cause is unknown, understanding this condition and how to support your dog is key to managing it effectively.

At Woofland, we believe that even lesser-known conditions deserve attention—and that the right environment and daily routines can make a meaningful difference.

This video shows a dog experiencing an idiopathic head tremor—gentle, involuntary head movements while the dog remains alert and responsive. A helpful reference for pet owners looking to understand what IHT looks like in real time.

What Are Idiopathic Head Tremors?

Idiopathic Head Tremors are involuntary, rhythmic movements of a dog’s head, usually side-to-side (like saying "no") or up-and-down (like saying "yes"). These episodes can last a few seconds to a few minutes, often while the dog is resting or relaxed.

They typically appear in young to middle-aged dogs and are more common in certain breeds like Dobermans, Bulldogs, Boxers, and Labradors. While the condition is not harmful or painful, it can be alarming to witness. Most importantly, IHT is not a seizure, and affected dogs are fully conscious and responsive during episodes.

How to Tell Idiopathic Head Tremors Apart from Other Conditions

Distinguishing Idiopathic Head Tremors (IHT) from other medical issues is crucial for proper care. Unlike seizures, which often involve loss of consciousness, muscle rigidity, and uncontrolled movements, dogs with IHT remain alert, responsive, and can sometimes be distracted mid-tremor. Other causes of head shaking, such as ear infections, toxin exposure, or low blood sugar, are usually accompanied by additional symptoms like balance issues, nausea, or behavioural changes. In some cases, a deficiency in B vitamins, particularly B1 (thiamine) and B6 (pyridoxine), has been associated with neurological disturbances, including tremors. A thorough veterinary exam, blood work, and dietary evaluation can help rule out these causes and confirm whether your dog is experiencing IHT.

What Triggers Idiopathic Head Tremors?

Although the cause is unknown, certain patterns suggest that episodes may be linked to:

• Stress or anxiety

• Overexcitement or anticipation

• Changes in routine or environment

• Low blood sugar in some cases

Understanding your dog’s triggers is important, and this is where a stable, well-managed routine, like one offered through a structured dog daycare, can be helpful.

How Dog Daycare Can Help Dogs with IHT

While there’s no cure for IHT, routine, emotional stability, and reduced stress can make a difference in how frequently episodes occur. A quality dog daycare like Woofland provides:

🐾 Routine and structure – Dogs thrive on predictability. Regular drop-offs, meal times, and play sessions offer a sense of security.

🐾 Low-stress environment – A calm, cage-free setting can minimise the anxiety that may trigger tremors.

🐾 Mental engagement – Enrichment activities and social interaction can keep your dog mentally stimulated without overstimulation.

🐾 Trained staff – Our experienced handlers know how to spot signs of discomfort and respond calmly to dogs showing unusual behaviours.

Avoiding Isoxazoline in Dogs with Neurological Symptoms

For any dog experiencing unexplained tremors, it’s essential to be cautious about certain medications. Isoxazoline-based flea and tick preventatives (such as NexGard, Bravecto, Simparica, and Credelio) have been associated with neurological side effects in some dogs, including tremors, ataxia, and seizures.

If your dog has a history of head tremors or any neurological signs, talk to your vet about alternative parasite prevention options. Always read medication labels and ask questions before starting a new treatment.

What to Do if Your Dog Has a Head Tremor

• Stay calm – Don’t panic; most episodes are short and harmless.

• Distract gently – Calling your dog’s name or offering a treat may interrupt the tremor.

• Document – Keep notes or videos of when and how episodes occur.

• Consult your vet – Rule out other conditions like seizures, ear infections, or metabolic issues.
