While scrolling through pictures of dog tumors and cysts can be a little scary, nothing compares to the fear of not knowing what a sudden bump on your dog might mean.
Of course, each node has its unique appearance and characteristics. For instance, although some might be pink or white, others could manifest as dark masses. Recognizing these variances is essential for prompt action.
In this article, a total of 24 pictures of lumps on dogs are shared for your reference. Yet, note that they are only examples, and you should never attempt to diagnose your pet’s condition based on these images alone.
Pictures of Tumors, Cysts, Lumps, and Warts in Dogs
When a dog’s skin begins to develop unusual growths, it could be an early sign of illness. From cancers to other deadly skin disorders, the list of possible causes is long and varied.
Here are some pictures of dog tumors and cysts that you can use to identify any changes in your pet. Images of warts and skin tags are also included so you can learn what these non-harmful conditions often look like.
Dog warts resemble tiny cauliflower heads, often appearing whitish, grayish, or flesh-colored. They are benign growths and can show up alone or clustered together.
Years ago, my dog had a bump near her tooth. On closer inspection, it was soft, with parts resembling cobblestone. The vet identified it as an epulis. Thankfully, it was non-cancerous and was easily removed via surgery.
Lipomas are harmless tumors composed of fat cells. Commonly found on older dogs’ abdomens, they start small. However, their growth can become quite expansive, making early observation essential for pet care.

4. Skin Tags
Skin tags are benign, tear-shaped lumps of tissue that form in the top layers of skin. They can occur anywhere on a canine’s body, including its legs and elbows, as well as around its eyes and mouth.
Melanoma in dogs appears as raised bumps, often dark in color. Their size can vary, sometimes reaching up to three inches. Although most melanomas are harmless, others can be cancerous, so monitoring is crucial.
Abscesses in canines stem from bacterial infections. These growths are filled with pus and can be painful to touch. Depending on their stage, they might feel warm, soft, or firm when examined.
7. Oral Papilloma
Oral papillomas, commonly called mouth or oral warts, look much like sea anemones. These growths typically affect young dogs, especially those under two years.
8. Interdigital Cysts
Interdigital cysts, also known as furuncles or follicular cysts, are red, inflamed bumps between a dog’s toes. If these nodules become infected, they can release a cream-colored fluid.
9. Sebaceous Cysts
Sebaceous cysts are benign growths usually arising from blocked hair follicles. They appear as lumps that vary from firm to soft. Further, filled with fluid, these cysts can be painful and itchy for pooches.
Adenocarcinoma is an anal gland tumor growing within or near a pup’s anus. Starting small, it can gradually expand. These tumors can be benign, but some may turn malignant, requiring vigilant observation and care.
11. Ocular Neoplasia
Ocular neoplasia refers to tumor growth in a dog’s eye, specifically on the eyelid. These growths can be either harmless or cancerous.
12. Mast Cell Tumors
Mast cell tumors are malignant growths from specific blood cells tied to allergies and inflammation. They appear pink or white and might be hair-covered or ulcerated.
13. Testicular Tumors
Testicular tumors are frequent in older, unneutered male dogs. They manifest as nodular enlargements, making one testicle appear bigger or abnormally shaped.
14. Inverted Papilloma
Inverted papillomas are rare in dogs, presenting as dome-shaped dermal nodules. They are firm, dark, and have a scaly surface.
15. Soft Tissue Sarcoma
Soft tissue sarcomas form from a dog’s connective, muscle, or nervous tissues. These cancerous tumors feel soft yet firm and are typically non-painful. However, they can grow significantly.
16. Mammary Gland Tumors
Mammary gland tumors in canines show up near or within the nipple. These masses can be soft or hard, with colors ranging from pink to red or purple. Often large, some might even be ulcerated.
17. Squamous Cell Carcinoma
Squamous cell carcinoma is a rare yet highly cancerous tumor. Usually found on a dog’s skin, mouth, or nail beds, it appears small, irritated, red-colored, and bumpy.
18. Transmissible Venereal Tumor
Transmissible venereal tumors are ulcerated bumps that spread between dogs via mating. These tumors typically surface in the penile or vulva regions, appearing as cauliflower-like nodules.
Osteosarcoma is a fast-growing bone tumor. It typically forms in a dog’s limb bones. The result is a firm swelling beneath the skin that doesn’t easily move.
Meningioma is a tumor found in the brain lining, causing noticeable head swelling. It most often affects large-sized canines. Despite being non-cancerous, it can cause serious health issues and needs vet attention.
21. Metastatic Neoplasia
Mets, or metastatic neoplasia, is when a pooch’s cancer spreads from its original site. It leads to raised and inflamed areas on the body.
22. Acanthomatous Ameloblastoma
Acanthomatous ameloblastoma is a benign oral tumor in dogs, common in those aged 6 to 10 years. While not cancerous, it can aggressively affect mouth bones, requiring immediate removal.
23. Post-traumatic Sarcoma
Post-traumatic sarcoma is a tumor that emerges after injuries, exposure to foreign objects, or radiation. Prompt recognition and treatment are essential to manage this condition in canines.
24. Uveal Melanoma
Uveal melanoma in dogs starts as brown or black masses on the eye’s surface. As it grows, it can become a large pigmented tumor inside the eye. This can lead to vision issues, discomfort, and glaucoma.
