Why My Dog Has Bumps, Lumps, and Cysts on Body

The general health of a dog can be seen by their appearance. Dogs may experience bumps, lumps, and cysts as a result of normal aging, or could be indicators of a health issue.

There are two kinds of bumps and lumps on dogs they have: cancerous (cancerous) as well as benign (not cancerous). But, it is difficult to determine the severity or type of a tumor just by taking a look. A veterinarian will take samples of cells in order to determine the cause and the appropriate treatment program.

Different types of Bumps and Lumps on Dogs

Here are a few common skin conditions that can be found in dogs, and information on how they appear and what you should look for:

Benign Tumors

A benign tumor is not infected or likely to expand to other body regions.


A histiocytoma is a benign growth on the skin that typically occurs in dogs younger than two years old. They can be typically found on the front of the body of a dog typically on the legs or the head. Sometimes, they are observed in older dogs or other parts of the body.

Histiocytomas are fleshy and pink but they may grow and appear more sensitive before they improve. They usually disappear in time, with no treatment. They result from the lymphocytes of the skin’s immune system. They can be identified by microscopic inspection of a small amount of cells from the tumor.


The lipoma could be present anyplace on the body of a dog but it’s most often seen on the legs and trunk. Lipomas originate from fat cells that reside under the skin, or in the muscle tissues. They are usually seen during the aging process of obese dogs. They can grow to be very large or show up in different places.

A vet can detect the existence of a tumor by taking a small amount of cells from the growth and looking for droplets of fat. There is no treatment needed however, these must be monitored for sudden changes. They’ll begin to grow larger as time passes, and can cause discomfort to your pet if they’re situated in an area that hinders movement. If the lipomas begin to irritate your pet, it’s time to think about surgical removal.


A papilloma that develops in puppies is a contagious wart-like growth that typically occurs around and in the mouth. When dogs get older, they could be observed around the eyes or other body parts. Papillomas result from a viral infection that could be transmitted through contact with an affected pet or by contaminated objects such as toys and food bowls.

They look tiny with a fleshy and round appearance with a cauliflower-like feel on the surface. Some will dry up and disappear within some months, when your dog’s immunity develops. The most severe cases can cause difficulty swallowing or eating and may require surgical removal. Other treatments and medicines can be found, such as crushing the warts to increase your immune system.

Another form of papilloma is an enlargement of the skin that is more prevalent in dogs of older ages. They are typically single and do not result from viruses. These bumps can be covered with a hardened layer that resembles an ear of cauliflower. Inverted papillomas can also be noticed in dogs that are young, particularly in the lower abdomen. If the growth causes discomfort to the pet, removal surgery is an alternative.

Skin Tag

The skin tag develops in the areas where the dog’s skin rubs against each other. These are overgrowths of connective tissue of the skin. They have similar to the color of the skin, but they extend from the skin’s surface with thin stalks.

Skin tags are common among older dogs and some breeds. There is no treatment needed however, they can be surgically removed if cause discomfort.

Sebaceous Gland Tumor

It is a sebaceous gland cancer that can be found in dogs who are old. They’re typically smaller than a pea and can develop in any place. Some may leak or release the material, which makes an outer layer. Large breeds usually develop these on their heads, particularly their eyelids. They might be black. Treatment is not needed however, surgical removal could be considered if the growth becomes bothersome.


Meibomian gland tumors are benign and slow-growing. It develops in the meibomian gland on the outer edge on the upper eyelid. The tumor may stick out or extend within the eyelid. They can become inflamed, itchy and painful or even ulcerated. They may also cause irritation of the cornea or conjunctiva.

Large tumors can cause issues whenever your pet blinks due to their increased tear staining and tear tearing. They can be identified by their appearance and position and are removed through surgery or be frozen to facilitate removal. They do not usually recover after removal, though growth regrowth is possible.


An Epulis is a normal benign growth that is found in the mouths of dogs. They can form when the tooth rubs against gums, similar to an underbite in the brachycephalic (flat-faced) dogs.

Smooth, fleshy pink bumps form on the gums near the surface of an incisor or canine or premolar tooth. They can appear like a tree as a mushroom or in a non-moving mass. They also may be bony in the interior. Certain kinds can infiltrate bony tissue.

The diagnosis of an epulis can be determined by identifying it through appearance, and then confirming it through an examination. A x-ray scan of the head of your dog will reveal whether it has invaded nearby tissues. These tumors should be eliminated surgically, as well as the tooth adjacent to it and any bony tissue which could be affected. They usually do not grow again when the entire tumor has been eliminated. Radiotherapy can be helpful in instances where the tumor is not operable.

Follicular Cysts

Follicular cysts are huge benign bumps on the skin that develop upwards from hair follicles. They could release a thick substance that is white or yellow when you press them. When they get larger they could cause pain or itching.

The types of cysts mentioned above are detected by physical examination. They could be confirmed by microscopically examining a small number of cells that have been aspirated using a needle. Follicular cysts could be infected which requires antibiotic therapy. If they grow or are painful, they can be surgically removed, and they should not recur.

Perianal Adenomas

Perianal Adenomas are benign growths that are common in males over the age of neutered dogs. They develop from glands of oil near the anus. They can also develop in similar glands on the abdomen, back, and on tail.

They typically appear as small lumps. The larger tumors can cause bleeding ulcers and may make the anal canal smaller, making it difficult for your dog to poop.

Most male dogs can be treated with castration only however large or ulcerated tumors may also need to be surgically removed. Females are better off after surgery however, the tumors can continue to grow. The use of lasers or freezing the growth might be necessary to prevent fecal incontinence if the surgery is performed on the anal sphincter.


They are harmless tumors that are found in mature dogs. They closely look like blood vessels. They are typically found on the legs of dogs and the trunk. They could be small growing or multiple circular, reddish-black lumps that look like blood blisters. They can grow large and may even form an ulcer. The best treatment is removal by surgery.


A mole is a dark-colored, raised or flat, benign growth that is found on the skin. It is commonly referred to as a mole. They can be found on places that are prone to trauma like the head, legs, and neck, most often in dogs that are older. The remedy is removal by surgery.


Trichoepitheliomas are tiny, harmless lumps that appear in hair follicles of mature dogs. They are cyst-like and are full of yellow condensed and cheesy granular substances. They can be found everywhere on the body, however, they are most common on the trunk and face. The procedure is surgical removal but they may develop in other places, even after surgery.

Epithelial cells that have been reshaping

The epithelial cells that are cornifying can be benign, benign growths which grow out on the skin’s surface and resemble hair horns. They are a result of hair follicles that can form anywhere on the body of a dog however they are most prevalent on the back, legs, and tail of dogs who are adults. There is no need for treatment until there’s evidence of an injury to the self an ulcer, or a secondary infection. Surgery is the best treatment.

Basal Cell Tumors

Basal cell tumors are benign tumors that develop on the ear, head neck, forelimbs, and neck of dogs who are older. They’re the most common type of raised swellings. They are small, single in shape, dome-shaped, and tiny. Some are hairless, ulcerated, or appear like stalks that protrude from the skin’s surface. They’re dark-colored and may develop into cysts that open up and discharge pus or fluid. Treatment is surgical of the cyst, particularly if the dog is feeling uncomfortable.

Malignant Tumors

Malignant tumors are tumors caused by cancer that may be invasive and can grow to organs.


Angiosarcomas can be characterized as highly dangerous blood vessel cancers which can appear different. The presence of red lumps on the skin or beneath soft tissue is often seen however, they can appear as the appearance of a bruise that is not well defined.

The different types of cancers grow quickly and can destroy the tissues around them. They also spread to liver and lungs. Angiosarcomas can develop in response to exposure to sunlight in breeds of dogs with white coats and short coats However, dogs with thick, dark coats are susceptible to developing these as well.

They are usually found on the lower part of the trunk, in the thigh, hip, and lower legs. A biopsy is needed to make the diagnosis. Laser and freezing procedures can be used to treat smaller tumors on the surface. The removal of a tumor by surgery is recommended for skin cancers that extend below the surface. Chemotherapy is also a possibility for any remaining cancerous cells.

Basal Cell Carcinomas

Basal cell carcinomas are raised or flattened growths that can be seen anywhere within the body a dog that is getting older. They can spread to the skin around them, creating new wounds however they are not likely to develop into other organs. Surgery is the best option with enough skin surrounding the area of tumors to make sure there are no cancerous cells left.


Liposarcomas are uncommon, but they can be present in male dogs of a certain age in the legs and chest. They may be lumps that are firm or soft which are not able to spread to other areas. Treatment involves surgical removal However, recurrence can be common. If this occurs then radiation therapy may be necessary.


Lymphosarcoma is rarely seen directly on the dog’s skin but it may show up as a skin tumor or in conjunction with internal tumors. It could appear as red patches, flaky skin with raised or ulcerated areas or even lumps that are deep in the skin.

There are two kinds of skin lymphosarcoma, which differ in their expected course and the response to treatment which is why it is essential to identify which one your dog has at an early stage. Treatment options include surgical removal as well as chemotherapy and radiation. These treatments are done either individually or in combination. These treatments can help reduce the symptoms of the disease but will not extend the life expectancy.

Mast Cell Tumors

Mast cells represent the largest frequent malignant tumors that dogs encounter. They are most often seen in older dogs but may be found at any time in dogs of all ages.

They can develop single growths everywhere on the body, particularly the lower abdomen, limbs and chest. These are larger, or quickly growing tumors, and those that grow in particular locations tend to expand. The appearance of these tumors can vary however, the majority are raised and are either firm or soft to the touch.

Your doctor will have to look at a small number of cells that are part of the tumor under a microscope before confirming the diagnosis. There are varying degrees of how serious these tumors are. Surgery is required. If the tumor grows or expands, other treatments such as chemotherapy and radiation therapy can be utilized.

Malignant Melanomas

Malignant melanomas are different kind of skin tumors that are common in older canines. They typically appear in the mouth, lips as well as nail bed of male canines. They look like large, ulcerated lumps that can be light, dark gray or pink. If they show up within the nail bed the toe will often be swollen.

They grow rapidly and could spread rapidly into other organs. Surgery is the most effective treatment however, it can be difficult and involves the removal of surrounding tissue in order to prevent repeat incidence. Radiation and chemotherapy aren’t effective options for treatment. There is a vaccine available to help reduce the size of tumors and can increase the lifespan of your dog.


Fibrosarcomas are the most common fast-growing malignant tumors found in canines. The majority of them are located in the legs and trunk and differ both in size and appearance. Skin’s surfaces appear lumpy. Those beneath the skin could appear firm and fleshy.

They may infiltrate muscles however, they rarely extend to other parts in the body. Treatment involves surgical removal, but total removal may not be feasible, and regrowth may be frequent. Fibrosarcomas are also treated using chemotherapy and radiation.

Squamous Cell Carcinomas

Squamous Cell carcinoma are located in two different places in a dog’s body in two places: on the skin’s surface or beneath a nail. They are typically seen as hard or raised, irregular and ossified areas. Most are single, however the sun’s exposure for long periods could result in multiple tumors. The tumors infiltrate the tissues surrounding them. Some of them are slow in spreading however others develop faster. Treatment requires total medical removal of the tumor as well as normal tissue.

What Do You Do If You Discover A Bump or Lump on Your Dog

If you notice an area of growth on your dog’s body, ask your veterinarian to conduct an examination. It’s important to note the site of the growth, the time it’s been present as well as any changes that have occurred since the first time you discovered it, and if your dog is concerned about the growth.

How Veterinarians Diagnose Lumps Bumps, Cysts, and Bumps on dogs

A small number of cells could require to be taken and examined under a microscope to make the diagnosis. It is possible to take an image of the outside of the growth making use of a syringe with a tiny needle to remove the cells in a small amount in the examination area (fine needle aspiration) or surgically removing a small sample (biopsy) in the presence of your dog is receiving general or local anesthesia.

Most veterinarians analyze impression smears and fine needle aspirates by staining them and then examining it with an optical microscope inside the office. Professionally trained veterinary pathologists are able to study these exact samples or tiny tissue samples to establish the cause of. Your vet will then identify the best treatment options and provide the anticipated outcome.

Therapy for dog Lumps Bumps, Lumps, and Cysts in Dogs

The options to treat the growth of the dog could include:

  • Monitor for changes
  • Removal with treatment with lasers or freezing
  • Removal of the lump surgically and without removing the normal tissue
  • Chemotherapy
  • Radiation

How to Keep Your Dog’s Bumps and Lumps

Keep a journal in which you note what you noticed first about the bumps or bumps and how many and where they’re located as well as the size, color, and texture, as well as whether they are movable or appear like it’s fixed in the underlying tissue, and if there’s any evidence of discharge. Note any shifts from day to night on any of these aspects.

Set up contact with your veterinarian as quickly as you can and bring the log as well as photos and any questions you have.


What would the sebaceous cyst of the body of a dog?

Sebaceous cysts are small, smooth swelling with sebum from oil glands that surround hair follicles. They may become infected, damaged and break, releasing a thin yellowish liquid.

What can you do to help the dog that has sebaceous cysts?

Sebaceous cysts should be monitored for any changes in the size or substance within the cyst. The cyst can rupture due to scratching and release a fluid-like substance. It is recommended to gently clean it with warm water and let dry. Any indication of sensitivity or infection in the area must be examined by a vet for treatment suggestions and perhaps surgical removal.

How can I eliminate bumps on my dog’s body?

The most secure way to remove bumps on the skin of a dog is to consult a vet identify the type of bump. Then , they’ll decide on the best plan to remove the bump with general or local anesthesia.

Does a bug bite trigger bumps on dogs?

A bug bite can cause temporary swelling on the dog’s. They can be itchy too. They are generally more distinct and rarely shrink, but stay the same or increase in size as time passes.

Do you think a belly lump is normal after spaying a dog?

No. The belly lump could indicate the reaction of an unburied suture or, occasionally, a hernia on abdomen wall. Consult your veterinarian in the event that your dog is suffering from an abdominal lump after having been spayed.

Do I need to have my pet’s lump removed?

It will depend on the kind of lump it is. A majority of benign growths do not require removal. If the growth is visible or irritates your dog or hinders movement A veterinary examination is necessary to determine the best treatment. For cancerous growths, your veterinarian will determine the best treatment.
