There are several types of lumps on a dog's paw, and identifying them is crucial for determining the best course of action.
A callus lump, also known as a paw pad callus, is a thickened area of skin on the paw pad. This type of lump is usually a result of repeated friction or pressure on the paw.
A wart lump, on the other hand, is a small, rough growth caused by the human papillomavirus (HPV). These lumps can be painful for dogs and may bleed if scratched or irritated.
A cyst lump is a fluid-filled sac that can appear on the paw, often due to an infection or blockage of a sweat gland.
What Are Lumps on a Dog's Paw?
Lumps on a dog's paw can be a cause for concern, but it's essential to understand what they are and how they're diagnosed.
Most of the time, your veterinarian won't be able to tell you exactly why your dog developed a tumor on their paw.
Some breeds may be predisposed to developing melanomas, including Chow Chows, Doberman Pinschers, and Golden Retrievers, especially if they have black skin.
Your veterinarian will examine your dog's paw to determine the next steps, and in some cases, they may collect tumor cells with a needle and syringe to examine them under a microscope.
Paws can be quite sensitive, so your dog may need sedation for this procedure.
Foot X-rays may be performed to see if the nail structure or underlying bone is affected. Your veterinarian may also recommend taking a sample of your dog's lymph nodes to check for cancer cells if they suspect the tumor is malignant.
Types of Lumps
Most lumps on dogs are benign, but it's always best to have them checked by a vet as soon as possible.
Some common types of lumps include sebaceous adenomas, which are benign tumours of sebaceous glands often found in Poodles, Maltese, Bichons and their crosses.
Sebaceous adenomas are usually slow-growing and can be identified by their classic appearance.
Sebaceous Adenoma
Sebaceous Adenoma is a common lump in certain breeds of dogs, such as Poodles, Maltese, Bichons, and their crosses.
They are actually benign tumours of sebaceous glands, not warts as some people might think.
A biopsy is necessary to confirm the diagnosis, but the classic appearance and slow growth of Sebaceous Adenoma make it relatively easy to spot.
If a Sebaceous Adenoma is ulcerated or being licked, it's best to remove it to prevent any potential problems.
Most Sebaceous Adenomas don't cause any issues, but it's still a good idea to get them checked out by a vet just to be sure.
Types of Lumps
Infiltrative lipomas can be firm and fixed in place, or soft and mobile, and tend to be 'locally aggressive' meaning they may spread to surrounding tissues.
Some lipomas grow between muscle layers which can lead to discomfort for your dog.
Lipomas are thought to occur due to a number of factors including diet, genetics, chemicals in the environment, drug interactions, and more.
Maintaining your dog's weight at a healthy level may help to prevent lipomas from occurring.
While fatty tumors are not malignant and will not metastasize, they may continue to grow and start to cause discomfort depending on their location.
Each dog is unique and lipomas can grow at varying rates.
Infiltrative lipomas can prove more challenging to remove since they typically grow quickly and surround nearby tissues leading to discomfort for your pup.
Your vet may recommend surgery to remove as much of the lipoma as possible followed by radiation therapy to deal with the remaining lipoma tissue.
Most lumps are benign and a biopsy or surgery isn't always needed.
Your vet can even identify most lumps straight away.

Diagnosing a Tumor
Diagnosing a tumor on your dog's paw can be a bit of a process, but it's essential to get a clear diagnosis so you can determine the best course of action.
Your veterinarian will start by examining your dog's paw to determine the next steps. They may also collect tumor cells with a needle and syringe and examine them under a microscope.
In some cases, your veterinarian may send a sample to an outside lab to find out what kind of tumor your dog has. Paws can be quite sensitive, so your dog may need sedation for this procedure.
Here are some common tests your veterinarian may perform to diagnose a tumor on your dog's paw:
- Needle aspiration to collect tumor cells
- Foot X-rays to see if the nail structure or underlying bone is affected
- Lymph node sampling to check for cancer cells
- Chest X-rays or abdominal ultrasound to check for cancer spread
- CT scan to evaluate the extent of the tumor and plan for surgical removal
A biopsy is also necessary to diagnose soft tissue sarcoma, which feels just like a lipoma and is often mistaken for one if a needle aspirate isn't done.
Symptoms of Tumors
Symptoms of tumors on a dog's paw can be subtle, but they're often noticeable if you know what to look for. A visible growth anywhere on the paw is a common symptom.
If your dog is limping, it could be a sign of a tumor. I've seen dogs limp due to a variety of reasons, but it's always a good idea to get it checked out.
Excessive licking of the foot is another symptom to watch out for. Dogs often lick their paws for various reasons, but if it's persistent, it could be a sign of a tumor.
Bleeding or sores on the foot are clear indicators of a tumor. If you notice any open wounds or bleeding, it's time to get your dog to the vet.
Changes to the appearance of a nail, such as a nail that splits or falls off, can also be a symptom of a tumor. Keep an eye on your dog's nails and report any changes to your vet.
Here are some common symptoms of tumors on a dog's paw:
- A visible growth anywhere on the paw
- Limping
- Excessively licking the foot
- Bleeding or sores on the foot
- Changes to the appearance of a nail, including a nail that splits or falls off
Diagnosing a Tumor in My Cat
A visible growth anywhere on your cat's paw is a symptom of a tumor, so if you notice anything unusual, take your cat to the vet.
Your veterinarian will examine your cat's paw to determine the next steps, and may collect tumor cells with a needle and syringe to examine under a microscope.
In some cases, your veterinarian may send a sample to an outside lab to find out what kind of tumor your cat has, and paws can be quite sensitive, so your cat may need sedation for this procedure.
Foot X-rays may be performed to see if the nail structure or underlying bone is affected, and your veterinarian may also recommend taking a sample of your cat's lymph nodes to check for cancer cells.
Other tests performed in-house may include chest X-rays or an abdominal ultrasound to check for cancer spread, or metastasis.
A biopsy is necessary to diagnose soft tissue sarcoma, a fast-growing, locally invasive tumor of connective tissue common in large breeds.
If you discover any form of lump or bump on your cat, it's best to have the lump examined by the vet, as it may be a harmless lipoma or potentially cancerous.
A fine needle aspiration may be performed to suction out a sample of cells, which will be examined under a microscope by a veterinary pathologist.
If your cat's results are unclear, your vet may recommend a biopsy or histopathology to determine a more clear diagnosis of your pet's condition.

- Changes to the appearance of a nail, including a nail that splits or falls off
Typically, a tumor on a cat's paw will be characterized as a small, hemispherical lump that can be felt just under the skin, and may feel soft and movable.
Treatment Options
Treatment options for a lump on your dog's paw depend on the type and size of the tumor.
Surgery is often necessary to remove the tumor, but it can be tricky to remove tumors on a dog's paw due to limited skin to close the incision.
Your veterinarian may recommend sending the tumor to a reference laboratory for evaluation to determine the tumor type and aggressiveness.
For some mast cell tumors, injectable medication like Stelfonta may be an option, but it has size and other restrictions.
If surgery isn't feasible, your veterinarian can discuss other options such as pain medications like carprofen or gabapentin to keep your dog comfortable.
Broaden your view: Dog Lump Removal Surgery Cost
In some cases, a soft bootie may be recommended to prevent injury to the mass.
Surgery to remove a paw tumor can take one to two hours, and costs can vary from a few hundred dollars for small mass removal to over a thousand dollars for larger tumors or limb amputation.
Home Remedies and Management
Recovery from surgery to remove a lump on your dog's paw typically takes around two weeks. Your dog may need to wear a recovery cone during this time.
If your veterinarian has prescribed antibiotics or pain medications, be sure to give them to your dog exactly as instructed. This will help prevent infection and manage any discomfort.
Survival rates for dogs with squamous cell carcinoma after toe amputation vary, but most are still alive one year later. Some studies suggest that 50% to 83% of dogs with this condition will survive the first year.
Medications: Not the Best Choice
Using antibacterial products and taking antibiotics can destroy the good bacteria your dog needs to balance and fight the pathogenic bacteria causing the infection.
Your dog's skin and gut have a microbiome, where 90% of his immune system is found, making it crucial to preserve the good bacteria.
Applying meds to the affected area isn't ideal, especially if your dog keeps licking it, which can lead to re-infection.
Incorrect antibiotic treatment is a major reason for the recurrence of interdigital cysts, often due to using the wrong type of antibiotics or antibiotic resistance.
Natural antibiotics can fight infection and support your dog's entire system, making them a better alternative to conventional medications.
