A pink growth on dogs is usually an indication of a non-cancerous tumor; however, only a few tumors are cancerous or malignant. Lumps or bumps could also be signs of acne because small dogs can sometimes get acne while they are going through puberty.

Whenever you find a pink bump on his snout, it is best to get your dog checked by his or her vet. Although most lumps are non-cancerous, leaving them untreated could cause difficulty in breathing for your furry friend.

What to Do If You Find a Lump or a Bump on Your Dog?

Finding a lump or bump always leaves a pet parent worrying about their dog’s health. There could be a lot of reasons why lumps occurred on your pet that we will discuss later in this article.

It is common for a dog to have a skin tumor, as reported by the Merck Veterinary Manual [1] . If you are not sure what caused a sudden lump or bump, it is advisable to get your dog examined by a vet.

Your vet will need to run a few tests to properly diagnose your pet’s nose. Often, the veterinarian will need to remove a few cells from the lump using a fine needle. Those cells are then examined under the microscope.

The vet would be able to tell if it is a tumor, or the vet may need to take a tissue sample to send it for a biopsy. Meanwhile, you can take your pet home, and within a few days, you would know if your dog has a cancerous tumor.

Some Common Types of Lumps on Dogs

Lumps or bumps on dogs can be further classified into two categories: Skin growth and tumors [2].

Skin Growths

Skin growth is basically a non-cancerous lump that can spread beyond the surrounding area. The vast area of a lump could be dangerous because it continues to expand more and could cause issues like difficulty in breathing due to the lump’s size, irritation caused by scratching the affected area, and restricted movement.

If these lumps are causing severe issues, then you should consider removing them. Below are a few skin growths on dogs:

  • Abscesses
  • Apocrine Cysts
  • Hematomas
  • Injection-site Reactions
  • Hives
  • Nasal Dermatoses


These lumps are formed due to infection from a wound or a bite. They could be very painful as they are filled with pus and blood under the skin. Your vet will properly examine the abscess, drain the fluid, clean the area with a sterile solution, and would prescribe antibiotics, if necessary.

Apocrine Cysts

Apocrine cysts are caused by blocked sweet skin glands. They appear like a human pimple. These cysts contain a clear fluid that may rupture and clear up on its own.


These can occur when a mass of blood gets cramped beneath the skin. It is sometimes confused with a blood blister. These can be very painful for your little friend and are also caused by trauma. The vet will need to perform a small surgery where it is opened up, and the blood blister is drained.

Injection-site Reactions

Sometimes your dog might develop a little lump or a bump beneath the skin after an injection. These are not painful but are quite tender, and it takes a few days or weeks to shrink or fade completely.


Hives on dogs are also known as Urticaria. They look a lot similar to the ones that appear on humans in the form of a red bump that causes itching or a rash. It is formed by the allergic reaction caused by a bee sting or direct contact with an allergic plant.

These allergies may cause swelling and gets resolved if it is mild. However, if it gets painful, then your vet will prescribe steroids that help in pain relief.

Nasal Dermatoses

It is a rare skin disease that is caused by sun exposure and affects the eyes  [3] , bridge and tip of the nose, and surrounding areas. This condition is also referred to as Nasal solar Dermatoses or Collie nose [4].

Skin Tumors

Skin tumors can be both benign (non-cancerous) and malignant (cancerous). However, both types of tumors can be treated. A tumor is a mass of tissues that are formed when abnormal cells get trapped. Read on to know more about skin tumors in dogs:

  • Histiocytomas
  • Lipomas
  • Sebaceous Gland Hyperplasia


These benign growths are dome-shaped, small, and hard to feel. They are common in younger dogs and usually appear on their ear flaps, legs, or head. They often disappear on their own without any surgery or treatment.


Lipomas consist of smooth and large lumps of fat cells that are soft in texture. They are very common in overweight dogs and are found on the body parts like the abdomen, front legs, and chest.

Sebaceous Gland Hyperplasia

This tumor usually forms when the sebaceous glands overproduce sebum. They look like warts in appearance, and these are commonly found on the torso, legs, and eyelids of dogs.

What Does Nose Cancer Look Like on a Dog?

A nose cancer looks somewhat like a swelling on the face. However, the face will appear more asymmetrical. The nose area of the dog will be more noticeable and will lose its original shape. There will be visible signs when a dog has a tumor or nasal cancer, and it depends on the types of benign tumor.

How Long Can a Dog Live With Nasal Cancer Without Treatment?

A dog could live up to 3 months to 6 months without detecting if he has cancer. In the initial stage, if a cancer is not detected, it is assumed that the dog is having some allergic or infectious reaction. The vet may prescribe steroids, nose drops, and antibiotics. In addition to this, if the dog gets relief from the symptoms, then cancer might not even detect.

Final Thoughts

So, what are the red bumps formed on your dog’s nose? It could be caused by several allergies or infections from an animal bite or wound or direct contact with a poisonous plant. However, as a pet parent, you need to maintain the good health of your dog’s coat and skin to prevent them from skin conditions.

Skin issues like lumps or bumps could be dangerous, and it is necessary to bring your dog to the vet if you find any. If a pink growth on dogs is detected and diagnosed in the earlier stage, there are higher chances of successful treatment.
