Wound & Laceration Repair

Even wounds that look minor on the surface can involve significant underlying damage or carry a high infection risk, particularly bite wounds — which are notoriously deceptive because small entry points can conceal deep tissue injury. Prompt professional care is recommended when:

• The wound is deep, gaping, or won't stop bleeding
• The injury was caused by another animal (bite wounds introduce bacteria deep into tissue)
• Foreign material such as glass, gravel, or plant material may be embedded
• The wound is located over a joint, near the eye, or on the paw pad
• The pet is licking or chewing at the site, which rapidly delays healing

Wounds left unassessed can develop serious infection, abscess, or require far more extensive repair than early treatment would have needed.

The approach is tailored to each wound's character:

• Cleaning and debridement: the wound is clipped, disinfected, and irrigated under pressure to remove bacteria and debris — the single most important step in preventing infection
• Assessment: depth, tissue viability, foreign material, and involvement of underlying structures are evaluated; X-rays may be taken if embedded material or bone involvement is suspected
• Closure: clean, fresh wounds are sutured or stapled in layers; contaminated or older wounds may be managed open for 24–72 hours before delayed primary closure, or allowed to heal by secondary intention with regular bandage changes
• Anesthesia or sedation: most wound repairs in pets require at least heavy sedation for thorough irrigation and pain-free closure; general anesthesia is used for deep or extensive injuries

Antibiotics are prescribed when infection risk is elevated, particularly with bite wounds or heavily contaminated injuries.

For wounds requiring sedation or anesthesia, standard pre-surgical preparation applies:

• Withhold food for 6–12 hours before the procedure when possible; in true emergencies this requirement may be waived with additional precautions
• Keep your pet from licking or chewing the wound on the way in — an improvised e-collar, a towel wrap, or gentle hand restraint all help
• Do not apply hydrogen peroxide, alcohol, or over-the-counter wound sprays to deep wounds, as these can damage tissue and make repair more difficult
• Applying light, clean pressure with a cloth to actively bleeding wounds is appropriate while en route to the hospital

Wound healing varies depending on location, depth, and closure technique, but general aftercare applies to most cases:

• An e-collar (Elizabethan collar) is essential — licking is the leading cause of wound breakdown and infection in pets
• Sutures or staples are typically removed in 10–14 days; sooner for facial wounds, longer for paw wounds under tension
• Bandaged wounds require scheduled bandage changes — typically every 1–3 days at first — to monitor healing and prevent moisture-related complications
• Limiting activity to leash walks and restricted play reduces tension on the closure and speeds healing
• Oral antibiotics are dispensed when warranted and must be completed even if the wound looks healed early

Signs of concern that warrant a same-day call include swelling, redness spreading away from the wound edges, foul odor, or discharge.

The most common complication of wound repair in pets is breakdown of the closure from licking — consistent e-collar use largely prevents this. Infection is another risk, especially in bite wounds, where bacterial contamination is essentially guaranteed despite thorough cleaning. Some wounds, particularly those over mobile joints or on the lower limbs, are prone to dehiscence (reopening) and may require repeated closures or alternative management. Deep bite wounds can develop abscesses (pockets of infection) days after they appear healed on the surface, which is why a follow-up visit is always recommended. Overall, wounds that receive prompt, thorough care heal cleanly in the vast majority of patients.
