Case Study: Application of Class 4 Laser Therapy in Treating Scrotal Infection Post-Neutering in a Dog

Introduction

Scrotal infection caused by wound licking after neutering is a common post-operative complication in male dogs. It typically occurs when a dog self-licks or scratches the surgical site, leading to skin damage and the invasion of pathogenic microorganisms. Symptoms include localized redness, elevated skin temperature, exudation, and inflammatory infiltration. If not intervened promptly, it can lead to skin ulceration, suppuration, tissue adhesion, and even systemic infection.

Class 4 laser therapy is an advanced physical treatment in veterinary medicine for post-operative infections and wound recovery. It is safe, non-invasive, and highly effective in anti-inflammatory sterilization, pain relief, and promoting healing. This report documents the complete recovery process of a male dog with a scrotal infection using VETMEDIX (FotonMedix) laser equipment, providing a scientific clinical reference for managing similar complications.

05 Case Summary

Short-term Recovery: The veterinary team at Hangzhou Songzi Pet Hospital implemented a targeted Class 4 laser therapy protocol. During the treatment cycle, localized redness and elevated skin temperature gradually subsided. Wound exudation decreased significantly, the scope of inflammatory infiltration narrowed, and pain reactions were noticeably reduced. The patient’s licking and scratching behavior decreased, the wound surface dried and scabbed, and appetite and mental state returned to normal.

Long-term Follow-up: The patient continued to wear an Elizabeth collar and returned for regular check-ups after discharge. Follow-up results showed that the scrotal infection site had completely healed. The scabs fell off naturally, and the local skin returned to its smooth state. No common post-operative complications such as ulceration, tissue adhesion, or chronic infection recurrence were observed. The dog has returned to full activity and a healthy life.

Conclusion: This case demonstrates the significant clinical value of VETMEDIX small animal high-power laser therapy in treating scrotal infections following neutering. By utilizing Photobiomodulation (PBM) technology, deep tissue laser therapy non-invasively targets the infected area to improve local blood circulation, dissipate edema, alleviate pain, and inhibit the reproduction of pathogens. This provides clear advantages in clinical safety and rapid recovery.
