Poorly healing wounds in dogs are injuries to the skin or underlying tissue that do not heal within the normal time frame. These wounds often show no signs of improvement or may even worsen.
Can Occur with the Following Diseases:
Basics and possible causes
Wound healingWound healing is the natural process of repairing tissue damage, occurring in phases including inflammation, tissue regeneration, and wound contraction, to restore tissue integrity. is a complex biological process that occurs in several phases: inflammation, tissue formation, and remodeling. Each of these phases can be disrupted by various factors, which can lead to poor wound healingWound healing is the natural process of repairing tissue damage, occurring in phases including inflammation, tissue regeneration, and wound contraction, to restore tissue integrity.. A lack of nutrients, especially proteins, vitamins, and minerals, can delay healing, as these are essential for cell renewal and the formation of collagen, an important component of connective tissue.
One of the most common causes of poorly healing wounds in dogs is an infectionAn infection is the colonization and multiplication of pathogens such as bacteria, viruses, fungi, or parasites in an organism, which often, but not always, leads to a disease.. BacteriaBacteria are microscopic, single-celled organisms that exist in almost every environment on Earth. Some types of bacteria are beneficial or even essential to life, while others can cause disease., fungi, or viruses can enter the wound and disrupt the healing process. Infected wounds can be identified by redness, swelling, pain, and pus formation.
ChronicChronic refers to a condition or disease that is long-lasting or permanent. Chronic diseases often develop slowly and can lead to persistent or recurring health problems over time. diseases such as diabetes mellitus or Cushing’s syndromeA syndrome is a group of symptoms that occur together and indicate a specific disease or condition. A syndrome can be caused by various factors and is often complex in its diagnosis and treatment. can also impair wound healingWound healing is the natural process of repairing tissue damage, occurring in phases including inflammation, tissue regeneration, and wound contraction, to restore tissue integrity.. In diabetes, an elevated blood sugar level leads to reduced blood flow and nerve function, which delays healing. In Cushing’s syndromeA syndrome is a group of symptoms that occur together and indicate a specific disease or condition. A syndrome can be caused by various factors and is often complex in its diagnosis and treatment., an excess of cortisolCortisol is a steroid hormone produced in the adrenal cortex. It plays an important role in the body's stress response, as well as in the metabolism of proteins, lipids, and carbohydrates. Cortisol also helps regulate blood sugar levels and suppress the immune system. suppresses the immune systemThe immune system is the body's defense system against infectious agents such as bacteria, viruses, fungi, and parasites. It comprises a complex network of organs, cells, and molecules that work together to protect the body. and the body’s ability to heal wounds.
ImmunosuppressiveImmunosuppressive agents are medications or substances that specifically suppress the activity of the immune system. They are used in dogs and cats to treat autoimmune diseases, allergies, and to prevent rejection reactions after transplants. therapies, such as those used in the treatment of autoimmune diseasesAutoimmune diseases are conditions in which the immune system mistakenly attacks the body's own cells or tissues as if they were foreign substances. Examples in dogs and cats include autoimmune hemolytic anemia and systemic lupus erythematosus., can weaken the body’s defenses and thus impair the ability to heal. Certain medications, such as corticosteroidsCorticosteroids are a class of steroid hormones that occur naturally in the body and can also be produced synthetically. They have anti-inflammatory and immunosuppressive properties and are used in veterinary medicine to treat a variety of conditions., can also negatively affect wound healingWound healing is the natural process of repairing tissue damage, occurring in phases including inflammation, tissue regeneration, and wound contraction, to restore tissue integrity..
External factors such as poor hygiene, inadequate wound care, or a moist environment can also contribute to poor healing. A moist wound provides an ideal breeding ground for bacteriaBacteria are microscopic, single-celled organisms that exist in almost every environment on Earth. Some types of bacteria are beneficial or even essential to life, while others can cause disease. and can delay healing.

- Lethargy: A dog with a poorly healing wound may feel weak or tired, which may indicate a systemic infectionAn infection is the colonization and multiplication of pathogens such as bacteria, viruses, fungi, or parasites in an organism, which often, but not always, leads to a disease. or pain.
- Fever: An elevated body temperature may be a sign that the body is responding to an infectionAn infection is the colonization and multiplication of pathogens such as bacteria, viruses, fungi, or parasites in an organism, which often, but not always, leads to a disease..
- Loss of appetite: Dogs with pain or an infectionAn infection is the colonization and multiplication of pathogens such as bacteria, viruses, fungi, or parasites in an organism, which often, but not always, leads to a disease. tend to eat less.
- Excessive licking or biting at the wound: This behavior can further damage the wound and delay healing.
When to visit the vet?
A vet visit is necessary if the wound shows no signs of healing after a few days or worsens. A veterinarian should also be consulted immediately if there are signs of an infectionAn infection is the colonization and multiplication of pathogens such as bacteria, viruses, fungi, or parasites in an organism, which often, but not always, leads to a disease. such as pus, strong odor, or redness.
If the dog develops a fever, appears lethargic, or loses its appetite, this is an indicationIndication refers to a valid reason or rationale for using a specific treatment, medication, or medical procedure. It is based on the diagnosis and the patient's clinical condition. that the infectionAn infection is the colonization and multiplication of pathogens such as bacteria, viruses, fungi, or parasites in an organism, which often, but not always, leads to a disease. may be systemic and needs to be treated quickly. Veterinary monitoring is also important for chronicChronic refers to a condition or disease that is long-lasting or permanent. Chronic diseases often develop slowly and can lead to persistent or recurring health problems over time. diseases that could affect healing.
A vet visit is also required if the dog shows pain or the wound is deep and tissue or bone is exposed.
Symptom recognition for animal owners and veterinary diagnostic procedures
The pet owner can facilitate symptom recognition by regularly checking the condition of the wound to detect changes in color, size, or odor. The dog’s behavior, such as excessive licking or biting at the wound, should also be observed.
The veterinarian will perform a thorough examination, which may include a medical historyThe medical history is the systematic collection of a patient's medical history through questioning. It includes information about previous illnesses, treatments, allergies, and lifestyle habits., a physical examination of the wound, and, if necessary, diagnostic tests. These tests may include blood tests, cultural tests of wound swabs, or imaging procedures such as X-rays to identify deeper infections or foreign bodies.
An accurate diagnosisA diagnosis is the identification of a disease or condition by its symptoms and/or results from diagnostic tests. It is the first step in the management and treatment of patients. is crucial to identify the cause of the poorly healing wound and initiate appropriate treatment.
What can pet owners do and professional therapy options
The pet owner can take immediate action by keeping the wound clean and dry. Regularly cleaning the wound with an antiseptic solution can help prevent infectionAn infection is the colonization and multiplication of pathogens such as bacteria, viruses, fungi, or parasites in an organism, which often, but not always, leads to a disease.. It is important to treat the wound gently to avoid further injury.
Preventing licking or biting by applying a protective collar or bandage can also support healing. The dog should also be kept in a clean environment to minimize the risk of infectionAn infection is the colonization and multiplication of pathogens such as bacteria, viruses, fungi, or parasites in an organism, which often, but not always, leads to a disease..
A balanced diet rich in proteins, vitamins, and minerals can promote healing by providing the necessary support for cell regeneration. The pet owner should make sure that the dog gets enough rest so as not to hinder the healing process.
It is important to administer all medications prescribed by the veterinarian, such as antibiotics or pain relievers, exactly as directed to support healing and avoid complications.
Outlook on current research
