Why Do Dogs Develop Lumps?

As dogs get older, developing lumps and bumps becomes increasingly common.

Many are harmless changes associated with ageing, while others may be inflammatory, infected or cancerous.

Common causes include:

• Fatty lumps (lipomas)

• Sebaceous adenomas

• Sebaceous cysts

• Skin tags

• Warts

• Histiocytomas

• Mast Cell Tumours

• Soft Tissue Sarcomas

• Other skin growths

The important thing to remember is that appearance alone doesn't tell us exactly what a lump is.

​

Five Signs Your Dog's Lump Should Be Removed

Although every dog is different, there are several situations where your veterinarian is more likely to recommend surgery.

1. The Lump Is Getting Bigger

Growth is one of the biggest reasons we recommend reassessment.

Some benign lumps grow slowly over many years, while others can increase in size much more rapidly.

A growing lump is often easier to remove while it's still relatively small.

2. The Lump Is Causing Discomfort

If your dog is:

• licking it

• scratching it

• chewing it

• rubbing it on furniture

the lump may be causing irritation or discomfort.

Repeated self-trauma can lead to bleeding, infection and inflammation.

3. The Lump Is In A Difficult Location

Even a small lump can become problematic if it's located:

• on the eyelid

• between the toes

• around the mouth

• near the anus

• over a joint

These locations may interfere with normal movement or daily function.

4. The Diagnosis Isn't Certain

Many lumps cannot be accurately identified by appearance alone.

If there is uncertainty about what the lump is—or concern that it could be cancerous—your veterinarian may recommend:

• Fine Needle Aspirate (FNA)

• Biopsy

• Surgical removal with histopathology

Obtaining a diagnosis often provides the clearest path forward.

5. Early Surgery May Be Simpler

One of the advantages of removing a lump while it is still relatively small is that surgery is often:

• technically simpler

• associated with a smaller incision

• easier to close

• associated with a faster recovery

Waiting doesn't always make surgery harder—but sometimes it does.

When Might Monitoring Be Appropriate?

Not every lump needs immediate surgery.

Monitoring may be reasonable when:

• a Fine Needle Aspirate suggests a benign lesion

• the lump has remained unchanged for a long period

• surgery would present greater risks than benefits

• your veterinarian believes careful observation is appropriate

If monitoring is chosen, it's important to keep checking the lump regularly and arrange a reassessment if anything changes.

How Do Veterinarians Decide?

Choosing whether to monitor or remove a lump isn't based on one single factor.

Your veterinarian considers:

✔ Your dog's age and overall health

✔ How long the lump has been present

✔ Whether it is growing

✔ Its location

✔ Whether it feels attached to deeper tissues

✔ Whether your dog is bothered by it

✔ Fine Needle Aspirate or biopsy results (when performed)

Every patient is different, which is why treatment recommendations should always be individualised.

Can Waiting Make Surgery More Difficult?

Sometimes, yes.

Although some lumps remain stable for years, others continue to enlarge over time.

As a lump grows it may:

• require a larger incision

• become more difficult to close

• interfere with nearby structures

• increase surgical complexity

This is one reason many veterinarians recommend removing suitable lumps before they become significantly larger.

When Should You Book an Appointment?

We recommend arranging a veterinary examination if your dog's lump:

• is new

• is growing

• changes shape or colour

• bleeds or ulcerates

• becomes painful

• is being licked or scratched

• interferes with walking or normal movement

Even if the lump turns out to be harmless, having it assessed provides reassurance and helps you make informed decisions.

Frequently Asked Questions

Can a benign lump become cancerous?

Generally, benign tumours do not transform into cancer. However, a lump that appears benign can sometimes already be malignant, which is why appearance alone is not enough to make a diagnosis.

Can my old dog still have lump surgery?

Many senior dogs safely undergo anaesthesia every day. Age alone is not a disease. Your veterinarian will assess your dog's overall health and discuss whether pre-anaesthetic blood testing or additional precautions are appropriate.

Should every lump be sent for histopathology?

Not necessarily, but histopathology is the most reliable way to determine exactly what a lump is and whether it has been completely removed.

Can several lumps be removed during one operation?

Yes. Many owners choose to have multiple lumps removed during the same anaesthetic, which is often more cost-effective than scheduling separate surgeries.
