Understanding Grey Warts and Swelling in Older Dogs: Should You See a Vet?

As dogs age, it’s common for them to develop skin growths, such as warts, which are often benign and not life-threatening. However, when a wart on your dog’s face is accompanied by hard swelling underneath, it’s a signal that further evaluation might be needed. Understanding what might be causing these symptoms and knowing when to seek veterinary care is essential for your dog’s well-being.

What Are Warts in Dogs?

Warts in dogs, also known as papillomas, are skin growths caused by the canine papillomavirus. They are more common in younger dogs but can appear in older pets due to their weakened immune systems. While warts are usually harmless, secondary issues can arise when there’s swelling or irritation beneath the wart.

Possible Causes of the Hard Swelling Under the Wart

1. Inflammation or Infection

Warts can become irritated or scratched, leading to inflammation or infection. Bacteria may enter the tissue, causing redness, swelling, and pain.

2. Abscess Formation

If the wart or surrounding tissue has been injured, an abscess (a pocket of pus) may develop under the skin. Abscesses are typically firm, warm to the touch, and may cause discomfort.

3. Sebaceous Cyst

A sebaceous cyst, often mistaken for a swelling, could form under or near the wart due to blocked oil glands.

4. Tumor or Growth

Although most warts are benign, underlying growths such as mast cell tumors or other skin masses may coexist with the wart. These require professional evaluation to rule out malignancy.

When Should You See a Veterinarian?

It’s advisable to have any unusual swelling, especially under a wart, examined by a veterinarian. Here are signs that indicate the need for a vet visit:

• The swelling is hard and growing in size.
• The area around the wart is red, painful, or leaking pus.
• Your dog shows signs of discomfort, such as pawing at the wart or swelling.
• There is a sudden change in the size, color, or texture of the wart.

What to Expect at the Vet

When you visit the vet, they will likely perform the following:

1. Physical Examination

The vet will assess the size, texture, and location of the wart and swelling.

2. Fine Needle Aspiration (FNA)

A small sample of the swelling may be collected using a fine needle to determine whether it’s an infection, cyst, or tumor.

3. Biopsy or Skin Testing

If there’s suspicion of a malignant growth, a biopsy may be done to analyze the tissue.

4. Treatment Recommendations

• For Infections: Antibiotics and anti-inflammatory medications may be prescribed.
• For Cysts: Minor surgery or drainage could be recommended.
• For Tumors: If the wart and swelling are part of a tumor, removal or further diagnostic tests may be necessary.

Can You Treat It at Home?

While home care can help manage minor issues, a hard swelling under a wart is best evaluated by a vet. However, you can take the following steps for initial care:

• Keep the Area Clean: Gently clean the wart and surrounding area with a pet-safe antiseptic solution to prevent infection.
• Prevent Scratching: Use an Elizabethan collar (cone) if your dog is scratching or rubbing the wart.
• Monitor Changes: Keep an eye on the size, shape, and texture of the wart and swelling, and take notes to share with the vet.

When Home Treatment Isn’t Enough

Attempting to pop or drain the swelling at home is not recommended, as it can worsen the infection or cause unnecessary pain. Swellings with unknown causes should always be addressed by a professional to rule out serious conditions.

How to Prevent Future Skin Issues in Dogs

1. Regular Skin Checks

Inspect your dog’s skin for new lumps, bumps, or changes, especially as they age.

2. Healthy Diet and Immune Support

Provide a balanced diet rich in nutrients to boost your dog’s immune system and skin health.

3. Protective Measures

Limit exposure to rough surfaces or sharp objects that could irritate the wart.

4. Routine Veterinary Visits

Regular check-ups can help catch potential issues early before they become serious.
