Canine sebaceous cysts are non-cancerous, and typically benign growths that can appear on a dog’s skin. They are most commonly found on their head, neck, and back. While these cysts can be bothersome to the pet, they usually don’t cause any serious health problems.
The exact cause of sebaceous cysts is unknown, although they are thought to be caused by a blockage in the sebaceous glands found in their skin. These glands secrete oils that help keep the skin healthy and hydrated. When these natural oils become blocked, a cyst can form.
Sebaceous cysts can appear as small lumps under the dog’s fur, or they could be larger bumps that protrude from their skin. They are typically painless, although they can become infected if left untreated. In some cases, the cyst can rupture and release a foul-smelling liquid or pus.
Although sebaceous cysts are mostly benign, it’s important to have them checked by a vet to rule out other potential causes.
Symptoms of Canine Sebaceous Cysts
Symptoms of Sebaceous Cysts can vary depending on the size and location of the cyst. Common symptoms include:
- Small lumps or bumps under the dog’s fur
- Redness and inflammation around the lump
- In some cases, a foul-smelling liquid or pus coming from the cyst
The cysts can sometimes be tender to the touch or feel warm to the touch. If your pet has any of these symptoms, it’s important to have them checked by a vet for diagnosis and treatment.
Diagnosing Canine Sebaceous Cysts
To diagnose a sebaceous cyst, the vet will typically perform a physical examination and take a sample of the fluid from the cyst. A biopsy can also be done if needed. The vet might also order blood tests and X-rays to rule out other potential causes.
Stages of Canine Sebaceous Cysts
Sebaceous cysts typically progress through three stages.
Stage 1
The first stage is the pre-cystic stage, when the blockage in the sebaceous glands occurs. During this stage, swelling and redness can be present but no visible cyst will form.
Stage 2
The second stage is known as the active cystic stage. During this stage a small lump or bump could begin to form. In some cases, the cyst will rupture and release a foul-smelling liquid or pus.
Stage 3
The third stage is known as the chronic cystic stage, during this stage the cyst can begin to grow and become more noticeable. At this stage, treatment is typically necessary.
Treating Canine Sebaceous Cysts
Treating sebaceous cysts will depend on the size and severity of the cyst. In some cases, the vet might be able to drain the cyst by making a small incision in it. If this is not possible, or if the cyst is large and severe, surgery could be necessary to remove it. In addition, antibiotics might be prescribed to help prevent an infection.
Sebaceous cysts are usually benign, but it’s important to have them checked by a vet for diagnosis and treatment. With proper care, these cysts can be managed and prevented from becoming larger or more severe.
Preventing Canine Sebaceous Cysts
The best way to prevent sebaceous cysts is to keep your pet’s skin clean and dry. Regular grooming and bathing can help keep their skin healthy and reduce the risk of blockages forming in their sebaceous glands. It’s important to check your pet regularly for lumps or bumps that might be hiding under their fur. If any are found, it’s best to have them checked by a vet.
