Vet’s 2025 Guide to Head Tilt in Dogs – Causes, Diagnosis & When to See a Vet 🐶

By Dr. Duncan Houston BVSc

💡 What Is Head Tilt?

A “head tilt” occurs when your dog holds its head at an angle, with one ear lower than the other. This can be a normal, momentary behavior or a worrying sign of underlying illness.

🎯 When It’s Just Curiosity or Learning

Dogs often tilt their heads when:

• Listening intently—tilting helps pinpoint sound direction (especially with floppy ears).
• Trying to see better—some muzzles partially obscure vision, so a tilt clarifies view.
• Concentrating or activating cognitive processing—gifted dogs tilt more when asked to fetch by name (43% vs. 2%).
• Loved behavior—tilts often get positive reinforcement, and dogs may repeat it intentionally.

⚠️ When It’s a Medical Concern

If head tilt is constant or accompanied by symptoms, it may indicate pathology:

• Vestibular disease (inner ear/balance system): symptoms include sudden tilt, circling, stumbling, nystagmus—can be idiopathic or due to infection, stroke, trauma, tumor, or hypothyroidism.
• Ear infections: external or middle-ear infections cause tilt, head shaking, ear pain or discharge.
• Neurological disease: tumors, strokes, and inflammation may cause persistent tilt, seizures, or head pressing.
• Toxicities or side effects: certain drugs, thiamine deficiency, or hypothyroidism can affect vestibular input.

🔬 Diagnosis: What Your Vet Will Do

• History & physical exam to rule out trauma, ear pain
• Otoscopic ear exam for infection or foreign objects.
• "
• Neurological evaluation to detect vestibular or central deficits.
• Diagnostics: bloodwork, urinalysis, thyroid tests
• Imaging (X-ray, CT, MRI) and CSF tap if neurologic disease suspected.

💊 Treatment Strategies

• Vestibular disease: Supportive care, anti-nausea meds, fluids Idiopathic cases often improve in 7–14 days.
• Ear infection: Clean ear canal, antibiotic/antifungal drops, oral meds if deeper infection.
• Neurological conditions: Treat underlying cause (surgery, steroids, chemo, stroke care)
• Address root causes: Adjust medications, treat thyroid disease, stop ototoxic drugs.

📈 Prognosis & Follow-Up

• Idiopathic vestibular disease: recovery within days to weeks, residual tilt may persist.
• Ear infections: excellent prognosis with prompt treatment
• Neurologic conditions: variable, depending on diagnosis and severity
• Regular rechecks, especially with recurrences or persistent tilts
