While this worry is valid, it’s important to remember that, just like humans, dogs can develop skin cancer too.

However, before jumping to conclusions, it’s crucial to explore all the potential reasons behind these black lumps. Let’s dive into the different causes and then discuss melanoma in more detail.
Causes of Pigmented or Black Lumps on Dogs
black growth on dog looks like tick There are several potential causes for pigmented or black lumps on a dog’s skin. Here are some of the most common:
black growth on dog looks like tick Ticks: Ticks are irritating pests that latch onto dogs while feeding on their blood. They can sometimes be mistaken for pigmented lumps. Veterinarians often remove ticks from dogs that have been confused with small skin lumps. If you’re unsure, learn how to safely remove a tick from your dog.
Scabs: Scabs form over healing cuts or wounds as a protective barrier. They can be pigmented and may appear as lumps. A closer inspection, after clipping the hair, often reveals that it’s just a scab rather than a tumor.
black growth on dog looks like tick Foreign Bodies: Objects stuck in a dog’s fur, such as food, chewing gum, or plant burrs, can be mistaken for pigmented lumps. A careful examination can usually distinguish these from other causes.
black growth on dog looks like tick Insect Bites: Bites from insects like wasps, bees, or spiders can cause localized inflammation that appears as a pigmented bump.
black growth on dog looks like tick Punctures: Trauma or bite wounds from other animals can lead to punctures that appear as black bumps on the skin.
black growth on dog looks like tick Abscesses: An abscess is a pus-filled pocket of infection, often caused by punctures or bites. The skin over an abscess can range from red to black in color, and cleaning the area can help determine if an abscess is the cause.
Warts: Canine viral papillomas (dog warts) are common, especially in young dogs. They typically appear as raised, pale bumps but can darken if infected or irritated. Licking or grooming the area can cause pigmentation changes, especially in dogs with light-colored fur. While generally benign, some warts may need surgical removal if they become infected or cause other issues.
black growth on dog looks like tick Histiocytomas: These small, raised lumps occur mostly in young dogs and are often found on the face or legs. Some dogs may lick them, causing a pigmented appearance. These lumps are usually benign and may resolve on their own, but a biopsy can confirm the diagnosis.
black growth on dog looks like tick Blisters: Blisters are fluid-filled pockets that can form due to friction or injury. They might appear pink or pigmented, particularly if they contain blood.
If your dog develops a pigmented lump, it’s important to consult with a veterinarian to determine the cause and appropriate treatment.

Cysts: Sebaceous cysts are small sacs that form when the sebaceous glands produce too much secretion. These cysts often appear as small bumps and are typically benign. However, they can become infected or open, causing redness or pigmentation. In most cases, sebaceous cysts don’t require treatment unless they become problematic.
Hematomas: A hematoma is essentially a bruise, which can appear blue or black in color. It usually occurs due to trauma, such as being hit by a car or an injury. Hematomas can also result from underlying bleeding disorders. If you’re concerned, it’s important to learn more about bruising and bleeding in dogs.
Mast Cell Tumors (MCT): Mast cell tumors are one of the most common types of skin tumors in dogs, accounting for around 20% of all cases. These lumps can form just under the skin and may appear anywhere on the body. Some dogs may develop multiple masses at once. MCTs can cause itching or licking, which can discolor the mass. In some cases, dogs may show additional signs of illness like weight loss, vomiting, or diarrhea due to substances released by the tumor. Early diagnosis and proper treatment are crucial.
Malignant Melanomas: This form of skin cancer affects pigmented cells known as melanocytes. While many melanomas are black or brown, some can appear unpigmented. These tumors can develop anywhere on the body, including the mouth, mucous membranes, and nail beds. Melanomas tend to grow quickly and can spread to other organs like the lymph nodes, liver, or lungs. It’s vital to catch malignant melanomas early, as there are several treatment options available, including a DNA tumor vaccine.
If you notice any unusual lumps or bumps on your dog, consulting a veterinarian is essential to ensure an accurate diagnosis and appropriate care.
How to Determine the Cause of a Black Lump on a Dog
If your dog has a pigmented lump, the most effective way to determine the cause is to have it professionally examined by a veterinarian. During the appointment, your vet will likely perform the following steps:
Complete Examination: The veterinarian will conduct a thorough physical exam, checking your dog’s eyes, ears, heart, lungs, lymph nodes, and abdomen to assess the size and condition of internal organs like the kidneys, liver, spleen, bladder, and intestines.
Examination of the Lump: The vet will closely examine the pigmented lump, taking note of its size, shape, depth, texture, location, and color. To get a clearer view, they may shave the hair around the lump, which is best done with professional help.
Recommendations: Based on the findings, including the lump’s characteristics and its potential to be cancerous, your vet will offer recommendations for further investigation. This could include a fine needle aspirate (FNA), biopsy, or even surgical removal (lumpectomy) of the lump. To definitively diagnose the lump, a tissue sample may be sent to a laboratory for histopathological analysis.
Seeking veterinary care is crucial in understanding the cause of the lump and ensuring your dog receives the appropriate treatment.
Treatment of Black Lumps on Dogs
The treatment for a pigmented lump on your dog will depend on its underlying cause. For example, an abscess may need to be drained, ticks will be removed, and skin infections can be treated with antibiotics. If the lump is determined to be a form of skin cancer, such as melanoma or a mast cell tumor, the treatment options will vary. These may include a combination of surgical removal of the mass, radiation therapy, and/or immunotherapy, depending on the specific type of cancer.
