Chronic, Non-Healing Wounds in Dogs
When to visit the vet?
Non-urgent see a veterinarian within 2–3 days
ORANGE for increasing redness/swelling, pus, strong odor, pain, fever, lethargy, or if bones/tendons are visible; RED for signs of sepsis or rapid tissue necrosis.

Definition of
Chronic non-healing wounds in dogs are injuries to the skin or underlying tissue that persist over a long period and do not respond to normal wound healing processes. They can have a variety of causes and often require a comprehensive veterinary diagnosis and treatment.
Can Occur with the Following Diseases:
Grundlagen und mögliche Ursachen
Chronic wounds occur when the body’s natural wound healing process is disrupted. Normally, wound healing goes through several phases: the inflammatory phase, the proliferative phase, and the maturation phase. In chronic wounds, this process is disturbed, either because the inflammatory phase is prolonged or because the subsequent phases do not proceed correctly.
A common cause of chronic wounds in dogs is infection. Bacterial infections can significantly hinder wound healing as they lead to a persistent inflammatory response. Fungal infections or parasitic diseases can also play a role.
Systemic diseases such as diabetes mellitus or Cushing’s syndrome can also impair healing. These conditions lead to poor circulation, weaken the immune system, and disrupt normal metabolism, resulting in delayed wound healing.
Traumas that exert continuous friction or pressure on the wound can also prevent a wound from healing properly. This includes poorly fitting bandages or harnesses that constantly rub against the same spot.
Another factor can be malnutrition. An inadequate supply of essential nutrients, particularly proteins, vitamins, and minerals, impairs the body’s ability to form new tissue and close wounds.
Typische Begleitsymptome
- Swelling: A non-healing wound can be accompanied by chronic swelling caused by a persistent inflammatory response.
- Redness and warmth: Affected areas may be red and warmer than the surrounding skin, indicating inflammation or infection.
- Odor: Chronic wounds can develop an unpleasant smell, often due to a bacterial infection.
- Pain: Dogs with chronic wounds often show signs of pain, such as increased licking or biting at the affected area.
- Discharge of fluid: Chronic wounds may secrete fluid that may be clear, bloody, or purulent.
- Behavioral changes: Dogs may become lethargic or change their eating habits when burdened by a chronic wound.
Wann zum Tierarzt?
A veterinarian should be consulted if a wound shows no signs of healing after a week or if the condition of the wound worsens. Persistent pain, excessive swelling, pus formation, or a strong odor are also indicators that a veterinary examination is necessary.
If a dog shows systemic symptoms such as fever, loss of appetite, or lethargy, this should be considered an emergency. These symptoms can indicate a systemic infection that needs immediate treatment.
Even if a pet owner is unsure about the cause or treatment of a wound, a veterinarian should be consulted. A professional assessment can help identify the underlying causes and develop appropriate treatment strategies.
Symptomerkennung für den Tierhalter und tierärztliches diagnostisches Vorgehen
Pet owners should regularly check their dog’s body for wounds, especially after walks or physical activity. Signs like licking, biting, or scratching at specific spots can indicate a wound.
During a vet visit, the doctor will perform a thorough physical examination and may order blood tests to rule out systemic diseases. A wound culture may be taken to check for the presence of bacteria or fungi.
X-rays or ultrasound may be required to assess the extent of tissue damage or to identify foreign bodies in the wound area. In some cases, a biopsy may be necessary to ensure there are no malignant changes.
The veterinarian will also assess the dog’s diet and general health to determine if malnutrition or other systemic problems are contributing to delayed healing.
Was kann der Tierhalter tun und professionelle Therapieoptionen
As a first step, the pet owner should keep the affected area clean. This can be done by carefully cleaning the wound with a mild antiseptic solution. It is important to be gentle to avoid further damage.
Wearing a cone can prevent the dog from licking or biting the wound, which could hinder healing. Alternatively, special bandages can be used to protect the wound.
The pet owner should ensure the dog receives a balanced diet rich in proteins and other essential nutrients to support healing.
Regular monitoring of the wound is important to detect changes or worsening early on. The pet owner should note all observations and questions to discuss them with the veterinarian.
If the dog is in pain, the pet owner can administer appropriate pain relief in consultation with the veterinarian. It is important not to administer any medication without veterinary guidance, as some human medications can be dangerous for dogs.
Ausblick auf aktuelle Forschung
Research into chronic non-healing wounds in dogs has made significant progress in recent years. Scientists are increasingly focusing on identifying factors that hinder wound healing in dogs, such as chronic infections, circulatory disorders, and a disturbed immune response. One of the most promising developments in this field is the use of growth factors and stem cell therapies to promote wound healing. These approaches aim to accelerate tissue regeneration and reduce the formation of scar tissue.
Another significant area of research is the use of biomaterials and wound dressings specifically developed for the treatment of chronic wounds in dogs. These materials can contain antimicrobial substances that inhibit the growth of bacteria and prevent infection. Furthermore, they are often designed to regulate moisture in the wound, which is crucial for optimal healing. The development of such technologies is based on extensive studies of the anatomy and physiology of canine skin.
Genetic research also offers new insights into the mechanisms that influence chronic wounds. By identifying genetic markers associated with delayed wound healing, researchers hope to develop personalized treatment approaches. These could make it possible to identify dogs prone to chronic wounds early on and take preventive measures. These genetic studies help deepen the understanding of the biological processes involved in wound healing and could lead to innovative therapies in the long term.
In addition to basic research, clinical trials are being conducted to evaluate the effectiveness of new treatment approaches. Both conventional and experimental therapies are tested to assess their safety and effectiveness in healing chronic wounds. These studies are crucial for developing evidence-based guidelines for veterinary practice and improving the quality of life for dogs with chronic wounds.
Another branch of research examines the influence of nutrition on wound healing. It is believed that certain nutrients, such as vitamins, minerals, and amino acids, play a significant role in supporting tissue repair. Studies in this area aim to develop nutritional guidelines that can promote the healing of chronic wounds. These findings could be beneficial not only for dogs but also for other animals and even humans.
Research on chronic non-healing wounds in dogs is a dynamic and growing field that continuously produces new insights. The combination of biotechnological innovations, genetic studies, and clinical trials offers promising potential to significantly improve treatment options for affected dogs and enable them to live a more pain-free life.
