Laser usage in veterinary dermatology has increased in popularity over the last several decades. Carbon dioxide (CO₂) laser is the leading modality in surgical laser for veterinary dermatology because of its unmatched performance with soft tissue, particularly the skin. This laser cuts and coagulates tissue via the photothermal effect of laser energy when interacting with soft tissues with high water content, such as skin. CO₂ laser modality has many indications for the diagnosis and treatment of dermatologic conditions in animals.
