Fatty Cysts and Sebaceous Cysts in Dogs: Causes, Symptoms & Care

Fatty cysts, a form of sebaceous cyst, are common lumps found in dogs caused by an over-accumulation of sebum, a natural oil produced by skin glands. While these cysts don't usually pose significant health risks, they can lead to discomfort and infections if neglected. Responsible pet owners can reduce the risk by maintaining good canine hygiene and providing a balanced diet.

Some Cocker spaniel puppies and other breeds with long or floppy ears tend to be more prone to cyst development, especially around the ears. Understanding their causes, symptoms, and treatments ensures your dog receives the best care.

What Causes Fatty or Sebaceous Cysts in Dogs?

These cysts occur due to excessive production of sebum, which normally keeps your dog's skin moisturised and coat glossy. Excessive sebum can clog pores, leading to cyst formation or sometimes acne. Causes include hormonal imbalances — often hereditary — or diets high in fats.

A balanced, appropriate diet tailored to your dog's needs can help maintain healthy sebum levels and skin condition, reducing cyst development. Hormonal causes, often seen in younger dogs, tend to improve naturally with age.

Can You Prevent Fatty or Sebaceous Cysts?

Prevention revolves around managing underlying causes. Feeding a nutritionally complete, low-fat diet and avoiding excessive fatty treats reduces sebum overproduction. Regular grooming and bathing help remove excess oils before pores clog.

If your dog experiences hormonal imbalances causing cysts, veterinary advice is essential. Many dogs outgrow these issues, but monitoring and good care play a key role.

Symptoms of Fatty or Sebaceous Cysts in Dogs

Lumps under the skin that you can feel, sometimes visible under the fur, are the first sign. These cysts are usually small — generally under 5cm — and skin-coloured or slightly bluish. Occasionally, they may ooze a thick white discharge as the body expels excess sebum.

• Common sites include head, neck, ears, upper legs, and armpits.
• The cysts are generally dry but may become inflamed if infected.

Finding any lump on your dog can be alarming. While usually harmless, prompt observation and vet consultation are wise to ensure it is a benign cyst and not something more serious.

How Are Fatty Cysts Diagnosed?

Your vet can confirm diagnosis through a fine needle aspirate (FNA), collecting cells from the lump to analyse. This helps rule out tumours and other growths. Sometimes, if necessary, a biopsy may be performed.

Treatment Options for Fatty Cysts

Fatty cysts often cause no pain and may disappear over time without intervention. However, if cysts grow large, become uncomfortable, or risk infection, removal might be recommended. Removal is typically a minor surgical procedure under general anaesthesia, with a good recovery and minimal recurrence risk.

Regular veterinary check-ups help monitor cysts for any changes that may require action. In rare cases, cysts can develop into malignant lumps, reinforcing the importance of professional monitoring.

Maintaining Healthy Skin and Coat

Good grooming and nutrition are essential to prevent cysts and support your dog's overall skin health. Use gentle, dog-safe shampoos and avoid harsh chemicals that can irritate skin or increase oil production.

A quality diet, possibly guided by your vet or a canine nutritionist, ensures your dog receives the right balance of nutrients, supporting skin, coat, and general wellness.

Responsible Pet Ownership and Seeking Vet Advice

Always consult your vet at the first sign of skin lumps, changes, or symptoms. Responsible care and timely intervention safeguard your dog's health and comfort.

Choosing a reputable breeder or adopting from ethical sources ensures your dog has a good genetic foundation, reducing risks of hereditary skin conditions like cysts.
