Why do Dogs Get Lumps Under ​Their Skin?

Just like humans, dogs can also experience a range ​of health issues.

One common concern that many dog owners may come across ⁢is finding lumps under⁢ their furry friend’s skin.

These lumps, known as subcutaneous masses, can be quite alarming.

There are several reasons why dogs can develop⁣ lumps under their skin. Some of the common causes​ include:


Lipomas are⁢ benign fatty‍ tumors ⁤that ‍often​ develop in older dogs.

These ⁢lumps are usually soft to⁤ the ⁣touch and can⁤ be ⁤easily moved⁤ under the skin.

While ⁣lipomas are generally harmless, it’s ⁢still ⁣important‌ to have ​them examined by ‍a veterinarian to ‌rule out any other ⁤potential health concerns.


Abscesses occur when bacteria ‌enter the body​ through a​ wound or infection.

These lumps are ⁢usually filled ⁢with pus and can be hot, painful, and red.

Immediate veterinary attention ⁢is crucial to prevent the infection from ⁣spreading and ⁤causing further complications.


Cysts are pockets⁤ of fluid that can form under a ⁤dog’s skin.

They ‌are ​often‍ non-painful, but they can grow in size‍ over time.‍

While some cysts may not require immediate⁣ treatment, it’s always a good‍ idea to have⁣ them evaluated ‌by a veterinarian to determine the​ best course of action.

In some‍ cases, skin ⁢lumps in dogs can be a result⁣ of allergic ⁣reactions.

Just‍ like humans, ​our ⁤furry‌ friends can experience allergies to certain foods, external ⁢parasites, ⁤or​ environmental factors.

These allergies can manifest⁣ as small, itchy bumps ​beneath the​ skin.

If you notice ‍your dog scratching or licking excessively, it could be a sign of an allergic reaction.

Consulting with a veterinarian can help identify the allergen and ​provide appropriate​ treatment options to alleviate your pet’s ⁣discomfort.

In the worst cases, lumps ⁢on a dog’s skin may be signs of a more serious​ condition, such as a malignant tumor.

While it’s natural‍ to worry about the worst-case scenario, keep in mind that ⁤not ‍all lumps are cancerous.

However,⁢ it’s‍ still important to have any suspicious or rapidly ‍growing lump evaluated by​ a veterinarian.

They may recommend further testing, such as a biopsy, ‍to determine the nature of the lump ⁢and the appropriate course ⁤of action.

How to determine ⁣if a dog's ​skin ⁣lump is benign or concerning

Treating Benign ⁢Skin Lumps in ⁢Dogs

If your dog has benign skin lumps underneath fur, don’t fret!

There are several ⁢effective treatment options for these ⁣benign skin lumps in dogs.

While some​ lumps may not require any treatment at ​all, others may ⁣need to be surgically⁢ removed if they become large or interfere with your dog’s ​daily activities.​

Your vet ‌may also recommend ‌a fine⁣ needle aspiration, which involves extracting ⁢cells from the lump with‍ a thin needle⁢ and examining them under a microscope.

In some cases, certain medications or⁣ prescription diets can also help shrink or prevent the growth of these benign lumps.

When Should Dog‍ Owners ​be Worried about a ⁤Skin Lump?
