Finding an unfamiliar lump while petting your dog can quickly become worrying. You may wonder whether it is harmless or needs veterinary attention.
Dogs can develop many types of skin and under-skin masses during their lives. Some are benign, while others may require prompt diagnosis and treatment. Appearance alone usually cannot determine what a mass is.
That is why having a new or changing lump examined is important. Your veterinarian can evaluate the mass and recommend testing when appropriate.
At Stevenson Village Veterinary Hospital, we understand how concerning these discoveries can feel for pet owners in Baltimore. Our veterinary team provides diagnostic and dog surgery services based on each pet’s individual needs.
What Causes Lumps and Bumps on Dogs?
A lump is a broad term for an abnormal swelling or growth on or beneath the skin. Dogs can develop lumps for many different reasons.
Some common possibilities include:
- Lipomas, which are fatty masses that are often benign
- Cysts that develop within or beneath the skin
- Warts and other superficial skin growths
- Abscesses caused by infection
- Inflammatory swellings
- Histiocytomas and other benign growths
- Mast cell tumors and other potentially malignant tumors
A soft lump is not automatically harmless. Likewise, a firm growth does not necessarily mean your dog has cancer.
Different masses can have similar appearances. Veterinary testing helps determine what type of cells are actually present.
When Should You Have a Dog’s Lump Checked?
It is wise to tell your veterinarian whenever you discover a new lump. Changes in an existing mass should also receive veterinary attention.
Schedule an evaluation if you notice:
- Rapid growth or a noticeable size change
- Bleeding or discharge
- Redness or inflammation
- An open or ulcerated surface
- Pain when the area is touched
- Persistent licking or scratching
- Changes in the lump’s shape, texture, or color
- Difficulty walking or moving because of its location
A small lump can still deserve attention. Size alone cannot reliably determine whether a mass is benign or malignant.
Early evaluation also creates a baseline for monitoring future changes.
How Does a Veterinarian Evaluate a Skin Mass?
Your veterinarian will usually begin with a physical examination. They may ask when you first noticed the lump and whether it has changed.
The veterinarian may examine its size, shape, texture, location, and mobility. They may also check whether the mass appears attached to deeper tissues.
Further diagnostic testing may then be recommended.
Fine-Needle Aspiration
A fine-needle aspiration uses a small needle to collect cells from the mass. Those cells can then be examined microscopically.
This procedure may provide valuable information without immediately removing the entire growth.
Biopsy and Pathology
Sometimes an aspiration does not provide enough information. Your veterinarian may recommend obtaining a larger tissue sample or removing the mass.
The tissue can then undergo microscopic examination by a veterinary pathologist. Additional diagnostics may also be appropriate depending on the suspected condition and your dog’s overall health.
Does Every Lump on a Dog Need Surgery?
No. Finding a lump does not automatically mean your dog needs an operation. Some benign masses can remain stable without causing pain or limiting normal activities. Your veterinarian may recommend monitoring these growths and checking them during future visits.
Monitoring can include measuring the mass and watching for physical changes. Taking dated photographs at home can also help document its appearance. However, monitoring should follow veterinary evaluation rather than an assumption that the growth is harmless.
When Is Mass Removal Surgery Recommended?
The decision to remove a mass depends on its diagnosis, behavior, location, and effects on your dog’s comfort.
Removal may be considered when a mass:
- Is malignant or suspected to be malignant
- Continues growing
- Changes rapidly
- Bleeds or repeatedly becomes irritated
- Develops an open surface
- Causes pain or discomfort
- Interferes with walking, eating, vision, or other functions
- Is repeatedly scratched, bitten, or rubbed
- Cannot be adequately diagnosed through less invasive testing
A benign mass can sometimes require removal because of its location. For example, a growth near a joint may interfere with comfortable movement.
Veterinarians consider the whole patient before recommending dog surgery. Your dog’s age, health, diagnostic findings, and anesthesia considerations can all influence the treatment plan.
Why Can Earlier Evaluation Make Mass Removal Easier?
Waiting for a lump to become very large can sometimes complicate treatment. Larger masses may involve more surrounding tissue. Certain tumors also require removal with a margin of apparently normal tissue.
The available surgical approach can depend heavily on the mass’s location and biological behavior. Earlier examination does not mean every growth should be removed immediately. Instead, it gives your veterinarian more information for making an appropriate treatment decision.
What Happens During Surgical Mass Removal?
The exact procedure varies according to the mass and your dog’s individual needs. Before surgery, your veterinarian may recommend an examination and diagnostic testing. These steps help the team plan anesthesia and the surgical procedure. During removal, the veterinarian excises the mass and any additional tissue considered necessary for that specific case.
The removed tissue may be submitted for histopathology. A veterinary pathologist can examine the tissue microscopically and provide important diagnostic information. Your veterinarian can then explain the pathology findings and whether additional monitoring or treatment is appropriate.
What Should You Expect After Mass Removal?
Recovery depends on the mass’s size, location, and the extent of surgery. Your dog may need an Elizabethan collar or another protective device. This helps prevent licking, scratching, and chewing around the incision. Pet owners should follow all instructions concerning medications, activity restrictions, and incision care.
Watch the surgical area for excessive swelling, bleeding, discharge, opening, or other unexpected changes. Contact your veterinarian if you notice anything concerning. Follow-up visits allow the veterinary team to check healing and discuss pathology results when applicable.
How Can You Monitor Your Dog for New Lumps?
Regularly running your hands over your dog’s body can help you notice changes earlier. Check the chest, abdomen, neck, legs, paws, back, and around the tail. Remember to look beneath thick fur when possible.
When you discover a lump, record its location and approximate size. Taking a photograph beside a ruler can provide a useful reference.
Avoid squeezing, puncturing, or attempting to drain an unexplained mass yourself. Instead, arrange a veterinary evaluation.
