Wound repair in dogs and cats costs roughly $300 to $2,500, depending on size, contamination, whether sedation or general anaesthesia is needed, and whether the wound can be closed at all. A small clean laceration under sedation sits at the bottom; a degloving injury needing staged reconstruction sits well above the top.
If you are standing over an injured animal right now, start with the triage below.
Is this a tonight problem?
Go now for: bleeding that soaks through pressure and does not slow, or any spurting bleeding; any penetrating wound of the chest or abdomen — including one that looks like a small puncture, because a sucking chest wound is immediately life-threatening; a small dog bitten by a large dog, even if the skin barely shows it; a wound with visible bone, tendon, or exposed abdominal contents; or an injured animal who is pale, cold, breathing hard, or unwilling to stand.
Go today for: any bite wound at all; wounds longer than about an inch or gaping open; wounds near an eye, a joint, or a paw pad; and any wound in an animal not up to date on vaccination.
First aid while you travel: firm, continuous pressure with a clean cloth. Do not lift it every few seconds to check — that restarts the bleeding. Even the gentlest pet may bite when in pain, so muzzle or restrain carefully.
The one that catches people out: bite wounds
A bite is an iceberg injury. The visible punctures are where the teeth entered. What matters is what happened between them: as the jaws closed and the animals pulled apart, the skin was crushed and torn away from the tissue underneath, creating a dead space that is now inoculated with bacteria.
The wound looks trivial and the damage is not. In the classic case — a small dog picked up and shaken by a large one — the skin can be nearly intact over a torn body wall, bruised lungs, or broken ribs.
Every bite wound is a contaminated wound. Infection is established within hours, which is why bite wounds are seen today and are usually explored, flushed, and often drained rather than simply stitched.
Why your vet did not stitch it
This is the most common complaint after wound treatment, and the open wound is usually the correct treatment.
Closing a wound seals whatever is inside it. If that includes bacteria, dirt, grass, or dying tissue, you have made an abscess — a closed pocket of infection under pressure that breaks down the repair in a few days and hurts considerably more than the original wound.
So veterinarians close wounds that are clean, fresh, and have healthy tissue with a good blood supply, and manage everything else open: flushing, removing dead tissue, and letting the wound drain and declare itself. Options then include delayed closure a few days later once the tissue is clean, or second-intention healing, where the wound is allowed to contract and fill in on its own under bandage care.
Timing matters too. Fresh, clean wounds are the best candidates for immediate closure; contamination increases with every hour, and heavily contaminated wounds are not good candidates even early on. There is no single universal deadline — the decision is about the state of the tissue, not the reading on a clock.
Drains are used when a pocket has been created that would otherwise fill with fluid. A drain looks alarming and is a sign of thorough treatment, not of a complication.
What treatment involves
Almost all wound repair requires sedation or general anaesthesia. Clipping, cleaning, and exploring a wound properly is painful, and a wound that is not explored properly is a wound half-treated.
The sequence is: clip the surrounding hair, flush copiously with sterile fluid, debride dead or contaminated tissue, explore the full extent of the pocket, then close — with sutures, staples, or tissue glue on small superficial wounds — or bandage open. Pain relief and, where infection is present or likely, antibiotics follow. Large or dirty wounds may need several procedures over a couple of weeks.
At-home care
Do use clean water or sterile saline to gently rinse, only if instructed, and only on wounds you have been told to clean.
Do not use hydrogen peroxide or alcohol. Both damage the healing tissue they are meant to protect and make wounds heal more slowly. Do not use human antibiotic or steroid ointments unless your veterinarian has specifically said to — the animal licks them off and swallows them.
Keep the e-collar on. A licked wound is the single most common reason a good repair fails. Owners routinely take the collar off out of sympathy, and the wound breaks down two days later. The saliva-heals-wounds idea is a folk belief; licking introduces bacteria and mechanically disrupts healing tissue.
Bandages must stay dry. A wet bandage wicks bacteria inward and can cause severe skin damage. Cover it for toilet trips and call if it slips, smells, or the toes above it swell.
Check daily for increasing redness or swelling, discharge or pus, a foul smell, heat, gaps opening in the incision, or a pet becoming lethargic, feverish or off food. Some swelling and pinkness in the first 48 hours is normal; increasing swelling after that is not.
Cost, itemised
- Small laceration, sedation and sutures: $300–$800
- Larger laceration under general anaesthesia: $800–$1,500
- Bite wound exploration, flushing and drain placement: $500–$1,500
- Degloving or extensive wound requiring staged management: $1,500–$5,000+
- Bandage changes: $50–$150 each, often several needed
- Radiographs to check for underlying damage: $150–$400
- Antibiotics and pain medication: $50–$200
Emergency and after-hours care adds a consultation premium. The difference between a $400 wound and a $2,000 wound is usually not the length of the cut — it is whether it was contaminated, how much tissue died, and whether it could be closed at once.
Who isn't a candidate
- Other: Primary closure is contraindicated for heavily contaminated, infected, or older wounds — closing bacteria inside creates an abscess. These are managed open, then closed later or left to heal by contraction.
- Other: Bite wounds are routinely closed when they should not be. The visible puncture is a fraction of the crushed and separated tissue underneath; most need exploration and drainage rather than a stitch.
- Concurrent condition: Unstable trauma patients need stabilisation first — a dramatic-looking skin wound is rarely what kills a hit-by-car patient, and chest or abdominal injury takes priority.
- Other: Tissue of doubtful viability should not be closed until it declares itself, which can take several days.
Common questions
How much does it cost to stitch up a dog?
Roughly $300 to $2,500. A small laceration with sedation and sutures runs $300–$800; a larger one under general anaesthesia $800–$1,500; bite wound exploration with a drain $500–$1,500; and extensive or degloving injuries $1,500–$5,000 or more. Bandage changes add $50–$150 each and after-hours care carries a premium.
Does a dog wound need stitches or will it heal on its own?
Small, shallow, clean wounds often heal without stitches. Wounds longer than about an inch, gaping, deep, over a joint, near an eye, or bleeding heavily generally need veterinary repair — and any bite wound should be seen the same day regardless of how small it looks. Wounds with visible bone, tendon, or chest or abdominal penetration are emergencies.
Why did the vet not stitch my dog's bite wound?
Because closing a contaminated wound seals bacteria inside and creates an abscess. Bite wounds are always contaminated and involve far more crushed tissue than the visible punctures suggest, so they are usually explored, flushed, and often drained instead. The wound may be closed a few days later once clean, or allowed to heal open. An open wound here is correct treatment, not neglect.
How do I care for my pet's wound at home?
Keep the e-collar on at all times — a licked wound is the most common reason a repair fails. Keep any bandage completely dry, rinse only with clean water or saline and only if instructed, and give all pain medication as scheduled. Do not use hydrogen peroxide, alcohol, or human ointments; they damage healing tissue and get swallowed.
What are the signs a pet's wound is infected?
Increasing redness or swelling after the first 48 hours, discharge or pus, a foul smell, heat around the site, gaps opening in the incision, or the pet becoming lethargic, feverish, or off food. Mild swelling and pinkness in the first two days is normal healing; anything that worsens rather than settles should be seen.
