Definition
The breaking open of lumps in the skin of dogs with a yellowish, brownish, or bloody discharge is a symptom that can indicate various skin diseases, including infections, allergic reactions, or tumors.
Can Occur with the Following Diseases:
- Benign Hair Follicle Tumor in Dogs (Trichoepithelioma)
- Sterile Nodular Inflammation of the Skin and Lymph Nodes in Puppies (Sterile Granulomatous Dermatitis or Lymphadenitis)
- Fungal Infection by Sporothrix Species in Dogs (Sporotrichosis)
- Malignant Tumor of the Upper Skin Layer in Dogs (Cutaneous Squamous Cell Carcinoma)
- Malignant soft tissue cancer that develops from stem cells in dogs (Malignant Fibrous Histiocytoma)
- Blastomyc Infection in Dogs (Blastomycosis)
- Malignant tumor of the skin glands in dogs (Adenocarcinoma of the skin)
Basics and possible causes
A dog’s skin is a complex organ consisting of several layers, including the epidermis, dermis, and subcutis. It serves as a protective barrier against external influences and harbors a variety of cells and microorganisms. The appearance of lumps in the skin can indicate inflammatory processes, infections, or abnormal cell growth.
A common cause for the breaking open of skin lumps is a bacterial infection. Pyoderma, for example, is a skin infection caused by bacteria such as staphylococci. These bacteria can easily penetrate injured or irritated skin and cause inflammation, which manifests as pustules, lumps, or abscesses.
Allergic skin reactions, such as those occurring in atopic dermatitis, can also promote the formation of lumps. In allergic reactions, an immune system hypersensitivity reaction occurs, which can lead to skin irritation and lump formation. These lumps can become inflamed and break open, leading to discharge.
Neoplastic changes, i.e., tumors, can also cause lumps in the skin. These can be benign or malignant. Mast cell tumors are one of the most common malignant skin tumors in dogs and can be characterized by their degeneration and breaking open, accompanied by discharge.
Typical accompanying symptoms
- Itching: Often accompanied by intense scratching of the dog, which can further irritate the skin and cause lumps to break open.
- Redness: The affected skin area may appear reddened, indicating inflammatory conditions.
- Swelling: Lumps may be accompanied by visible swelling of the skin, which may be sensitive to pressure.
- Hair loss: Locally limited hair loss around the lumps, often due to scratching or the inflammatory reaction.
- Odor: An unpleasant odor can emanate from the open lumps, especially if a bacterial infection is present.
- Lethargy: The dog may appear generally tired or listless, indicating the strain of the infection or inflammatory conditions.
- Loss of appetite: Sometimes the dog’s discomfort can lead to reduced food intake.
- Fever: In some cases, a systemic reaction with fever may occur, especially with extensive infections.
When to visit the vet?
A veterinarian should be consulted if the lumps in the dog’s skin break open and discharge a yellowish, brownish, or bloody secretion. This is particularly important if the lumps grow or multiply in a short time.
If the dog shows signs of discomfort, such as Fever, loss of appetite, or Lethargy, an immediate visit to the veterinarian is advisable to avoid serious complications.
A veterinarian should also be consulted for signs of pain or discomfort, such as excessive Scratching or licking of the affected area, in order to clarify the cause and begin appropriate treatment.
Symptom recognition for animal owners and veterinary diagnostic procedures
It is important for the pet owner to recognize the symptoms early. This includes observing the dog for signs of itching, redness, or swelling, as well as regularly examining the skin for unusual lumps or skin changes.
The veterinary diagnosis process usually includes a thorough physical examination of the dog to assess the extent and type of skin lesions. The veterinarian will likely also take a medical history to record the history of the symptoms.
For further clarification, the veterinarian may perform diagnostic tests such as skin biopsies, cytologies, or blood tests. A biopsy can help determine the type of lumps, while cytologies can provide indications of infections or inflammatory conditions.
In some cases, special tests, such as allergy tests or imaging procedures, may also be necessary to identify the exact cause of the skin changes.
What can pet owners do and professional therapy options
As a first measure, the pet owner should prevent the dog from further irritating the affected area. Wearing an Elizabethan collar can be helpful to prevent excessive scratching or licking.
It is important to keep the affected skin areas clean to minimize the risk of infection. Regular cleaning with antiseptic solutions can help prevent the spread of bacteria.
The pet owner should ensure the dog is provided with a balanced diet and sufficient fresh water to strengthen the immune system and promote healing.
It is crucial not to use self-prescribed medications or home remedies without consulting a veterinarian, as these could worsen symptoms or have undesirable side effects.
After the veterinary diagnosis and treatment recommendation, prescribed medications or topical treatments should be applied consistently and according to the veterinarian’s instructions to support rapid healing.
