Last updated:

Treating a wound on your dog is stressful. But when it refuses to heal, it becomes even more worrying. If you find yourself wondering what steps to take, we’ve gathered helpful information on common causes of non-healing wounds in dogs, basic first aid for wounds, and when to go to the vet below.

Common Wounds in Dogs

Injuries for dogs happen in a variety of ways during their daily activities. Common causes include:

  • Animal Fights: Scratches and bite wounds from other animals.
  • Outdoor Hazards: Cuts from sharp objects like glass or thorns during walks or play.
  • Human Accidents: Being stepped on, caught in doors, or even hit by a car.

A dog’s wound needs to be treated as soon as possible to prevent complications.

First Aid for Dog Wounds

If your dog gets a minor cut or scrape, you might be able to treat it at home with some simple first aid. Follow these steps to ensure the wound is treated properly so it can heal.

If the wound is deep, won’t stop bleeding, or otherwise makes you question your ability to treat it — go to the vet right away! It’s better to be safe than sorry when it comes to your dog.

Cleaning the Wound
Start by rinsing the wound under lukewarm water to remove dirt and debris. Use mild, antibacterial soap or a saline solution. Do NOT use alcohol or hydrogen peroxide, which can damage tissue. Pat the wound dry with a clean cloth.

Applying a Bandage
After cleaning, apply a sterile bandage to protect the wound. Place a non-stick pad over the wound and wrap it gently with medical tape or a self-adhesive bandage. Ensure the bandage is snug but not too tight to avoid restricting blood flow.

Keeping the Wound Clean and Dry
To prevent infection, keep the wound clean and dry. Change the bandage daily or as directed by your vet. Avoid getting the wound wet during baths or outdoor play. Use a waterproof wrap if needed when your dog goes outside and remember to take it off when you come in. If the bandage becomes wet or dirty, change it right away.

Monitoring for Signs of Infection
Watch for signs of infection, such as redness, swelling, warmth, or discharge (such as pus). If you notice any of these symptoms or a foul odor, contact your vet. Infections can delay healing and may require antibiotics. They can also make the wound much worse in a very short time.

What Causes Delayed Wound Healing in Dogs?

If you’ve been treating your dog’s wound for a few days and it’s not getting better, there could be underlying issues. Here are some common reasons why your dog’s wound won’t heal.

Infection
Infections are a frequent cause of non-healing wounds in both dogs and people. Bacteria causes swelling, redness, and discharge, slowing down the healing process. An infected wound may also develop a bad odor or cause your dog to have a fever, not eat or drink, and/or become lethargic.

Underlying Health Issues
Conditions like diabetes or immune system problems can affect how well your dog’s body repairs itself. If your dog has a known medical condition, it may take longer for wounds to heal, requiring additional care.

Excessive Licking or Chewing
Dogs may lick or chew their wounds to relieve itching or pain. Your dog’s just following their instincts, but doing so can reopen the injury or introduce bacteria. An E-collar (cone) might be needed to prevent your dog from disturbing the wound.

Foreign Objects in the Wound
Small debris, like splinters or glass, may become trapped in the wound, preventing it from healing. If the wound continues to ooze or remains painful after treatment, have it checked by a vet to ensure no foreign material is present.

When Should I See a Vet for My Dog’s Wound That Won’t Heal?

While it’s possible to manage minor wounds at home, seeking veterinary care is the best option for any wound. If your dog’s wound doesn’t improve with home treatment, it’s time to consult a vet. Professional care can help prevent complications and ensure proper healing.

Here’s when you should seek professional help:

  • 72-Hour Rule: If the wound doesn’t show signs of improvement within 72 hours of home treatment, it’s time to consult a vet.
  • Persistent Redness or Swelling: If the wound remains red, swollen, or warm despite treatment.
  • Foul Odor or Discharge: An unpleasant smell or abnormal discharge can indicate an infection.
  • Increased Pain or Sensitivity: If your dog seems to be in pain or the wound becomes more sensitive.
  • Excessive Bleeding: Ongoing bleeding or large amounts of blood.
  • Fever or Lethargy: If your dog develops a fever or appears unusually tired.
  • Your Abilities: If you feel uncomfortable treating the wound at any point, take your dog to the vet. Even if you’ve already treated it or made a mistake, your vet is the best person to help.

That’s a Wrap on Non-Healing Dog Wounds

Treating a wound is stressful for most people. When your dog’s wound won’t heal, you may feel even worse. It’s essential to follow prompt first aid and monitor your dog’s wound closely. If you face any issues or signs of infection, don’t hesitate to seek veterinary advice.

Remember that veterinary care is important if a wound doesn’t improve or if you notice any worrying symptoms. If you’re ever in doubt about your dog’s health, reaching out to a vet is always the best bet. They can help you prevent complications and help ensure your pup heals properly.
