Cutaneous Discharge in Dogs
Cutaneous discharge in dogs refers to the leakage of fluids from the skin pores that should not normally occur in this form or quantity. These fluids can be oily, watery, or purulent and often indicate a skin disease or systemic disease.
Can Occur with the Following Diseases:
Basics and possible causes
The skin is the largest organ in the dog and serves as a barrier against external influences, regulates body temperature, and enables the perception of touch. Cutaneous discharge can be an indication that this barrier function is disturbed. This can be triggered by various factors that are either internal or external.
A common cause of cutaneous discharge is a skin infection caused by bacteria, fungi, or parasites such as mites. These organisms can penetrate the skin barrier and trigger an inflammatory condition that leads to cutaneous discharge.
Allergic reactions are also a common cause of skin secretions. Dogs can react to various environmental allergens, such as pollen, mold, or house dust mites, as well as food allergens. These allergies cause itching and inflammatory conditions, which leads to increased secretion.
Hormonal imbalances, such as those that occur with diseases of the thyroid gland or adrenal glands, can also affect skin health. These imbalances often lead to changes in skin structure and function, which can promote cutaneous discharge.
In rare cases, cutaneous discharge may indicate an autoimmune disease in which the dog’s immune system mistakenly attacks its own skin cells. This leads to inflammatory conditions and damage that can manifest as cutaneous discharge.
Typical accompanying symptoms
-
Itching: A common accompanying symptom in which the dog scratches or licks itself more frequently, often on the affected areas of the skin.
-
Redness: The skin may appear red and irritated, indicating an inflammatory condition.
-
Swelling: Edema or swelling can be caused by fluid accumulation in the tissue and indicate an inflammatory reaction.
-
Skin lesions: Wounds, crusts, or ulcers may form, caused by scratching or by the infection itself.
-
Hair loss: Damage to the hair follicles can lead to local or extensive hair loss.
-
Unpleasant odor: A foul or rancid odor can emanate from the skin, especially in the case of bacterial infections.
-
Changes in skin texture: The skin may become thicker or thinner, depending on the underlying cause of the cutaneous discharge.
When to visit the vet?
A visit to the veterinarian is urgently required if the cutaneous discharge is accompanied by severe symptoms such as severe swelling, deep skin lesions, or behavioral changes. These signs indicate a severe infection or systemic disease that requires immediate treatment.
A veterinarian should also be consulted if the dog shows signs of pain, such as whining or reduced activity. Pain can indicate a serious inflammatory condition or a secondary infection.
If the cutaneous discharge persists or worsens despite home measures, it is important to seek professional help. Long-term untreated skin diseases can lead to chronic problems and increased susceptibility to infection.
Symptom recognition for animal owners and veterinary diagnostic procedures
Pet owners should pay attention to signs of skin changes in their dog, such as unusual moisture, discoloration, or odors. Regular grooming can help to identify such symptoms early.
The veterinarian will perform a thorough clinical examination to determine the exact cause of the cutaneous discharge. This may include taking skin samples for microscopic examination, culture tests to identify infectious agents, or blood tests to check for systemic diseases.
In some cases, an allergological examination may also be necessary to identify possible triggers for allergic reactions. This can be done through elimination diets or specific allergy tests.
What can pet owners do and professional therapy options
Until the veterinarian visit, the pet owner can gently clean the affected skin areas to remove excess secretion and reduce the risk of infection. Lukewarm water and a mild, dog-friendly soap can be used for this.
Wearing a protective collar can prevent the dog from scratching or licking the affected areas, which can prevent further skin damage and infections.
It is important to keep the dog’s environment clean and low in allergens to minimize irritation. Regular vacuuming and the use of air purifiers can help.
The dog’s diet should be checked to ensure that it is balanced and free of potential allergens. In consultation with the veterinarian, a special diet can be useful to alleviate skin problems.
