Clinical evidence update from Animals : an open access journal from MDPI

Clinical Context

Peer-reviewed veterinary literature continues to shape everyday decision-making for canine patients, especially when new evidence clarifies diagnosis, treatment selection, monitoring, or clinical outcomes.

What the Study Evaluated

A study published in Animals : an open access journal from MDPI in 2026 evaluated evaluation of Dual-Near-Infrared-Wavelength Photobiomodulation Therapy for the Treatment of Canine Otitis Externa: A Prospective Multicenter Pilot Study..

Key Findings

This is the first prospective multicenter study investigating photobiomodulation (PBM) in canine OE. Inclusion criteria required an Otitis Index Score 3 (OTIS-3; scale 0-3) ≥1 for erythema and discharge and a Budach cytological score ≥1+ (scale 0-4+) for Malassezia spp. and/or bacteria associated with keratinocytes/corneocytes. Twenty-two dogs with OE (38 ears) were enrolled and underwent five PBM sessions. When the discharge score was ≥2, a ceruminolytic ear cleanser was applied before treatment. OTIS-3, Budach cytological scores, and microbiological cultures were evaluated at T0, T2, T4, and T5. Pruritus was assessed using a 10 cm visual...

Why It Matters for Veterinary Professionals

For veterinary professionals, the practical value of this work lies in how the findings may support more structured clinical assessment, clearer monitoring, and more informed decisions for canine patients.

Practical Interpretation

The results should be interpreted in the context of the study design, population, inclusion criteria, and clinical setting. Application in practice should consider patient-specific risk factors, available diagnostics, local standards of care, and clinician judgment.

Clinical Takeaway

Overall, the study adds useful evidence for clinicians seeking to align daily practice with current veterinary research while maintaining a balanced, case-by-case approach.
