If that were the case, dog owners everywhere would be relieved. For those who have experienced the loss of a beloved pet due to cancer, finding an unexpected lump or bump may prompt thoughts such as “tumour” or “cancer”. A dog’s lumps and bumps are frequently benign, which means they aren’t cancerous. By reading this guide, you will be able to know, Soft Lump on Dog Under Skin: What Should You Do?.

You’re curled up on the couch with your dog when you get a jolt. You’re trying to recall the last time you rubbed this particular part of its body. It doesn’t take long before you’re bombarded with inquiries. Is this mass anything you’ve noticed before?  

As a result, you’re now faced with the ultimate question: Is cancer to blame? It’s easy for our brains to run wild and assume the worst when we don’t have access to the expertise of a veterinarian or test findings. 

However, fatty tumours are the most common type of bump. Benign refers to the absence of malignant cells. Malignant, or cancerous, lumps and bumps are found on dogs in less than half of all cases. It’s difficult to tell from the outside, as they can seem the same. 

Soft Lumps on Dog Under Skin What Should You Do  Guide

What does mean by soft lump on dogs under skin?

Bring your dog in for an examination unless you’re certain what’s causing a lump or bump. A vet visit should be scheduled as soon as you see any of these symptoms: rapid growth, redness or swelling, pus or a sore spot on the dog’s body. 

The greater the growth, the more difficult it is to operate on lumps in some locations like the face or paws. 

Your veterinarian is going to want to know the following information: 

If the growth happened overnight, it would be considered an emergency. 

Regardless of whether its form, colour, or size has shifted, it is still there. 

Whether or not your dog behaves differently, such as in terms of food or energy. 

The vet may use a fine needle to remove some of the lump’s cells. After that, they’ll examine them using a microscope. They can usually identify if it’s a fatty tumour right away. 

Your veterinarian may perform a biopsy on a small sample of tissue from the lump if it’s difficult to determine the cause. You’ll find out if it’s malignant in a few days. If this is the case, surgery will typically be able to get rid of the growth. 

Whether or not cancer has spread to other organs is more worrisome. Radiation or chemotherapy, or maybe both, might be in order if that’s the case. 

Lipomas are fat-filled benign (noncancerous) tumours that can move freely and grow slowly in senior dogs. Your dog’s follicles are delicate and easy to manipulate. While they can appear anywhere on your dog, the undercarriage, chest, or abdomen are the most usual locations to find them. Despite their unsightliness, tumours pose no health risk to your pet. A large majority of senior dogs have at least one of these benign tumours. 

There is no known reason for these benign but unsightly tumours, which are common in older dogs. 

Lipomas are non-cancerous tumours that don’t cause any symptoms. Most of the time, there’s no need to be alarmed! Infiltrative tumours, such as benign lipomas, penetrate muscle tissue and must be removed. Liposarcomas are cancerous tumours that can spread to the lungs, bones, and other organs. 

Even though your vet can determine the difference between a benign lipoma and malignant liposarcoma, the average pet owner cannot. Make an appointment with your local animal hospital if you notice a weird growth on your pet. If the tumour is not a lethal liposarcoma, a specialist examination will be needed to rule it out with certainty. 

7 Different types of soft lumps under the skin of a dog 

According to Healthy Paws Pet Insurance, evaluation of skin issues, especially lumps, was a prominent cause for pet owners to seek veterinary care in 2017. These common canine lumps and bumps are explained briefly so you know what to look out for and when to take your dog to the vet. 

1. Lipoma  

Fat-filled tumours known as lipomas are frequent in middle-aged and older dogs and are thought to be an inevitable byproduct of the dog’s ageing process. These circular, non-painful masses are soft and round, and they expand slowly.

Lipomas can occur in any dog breed, although fat or overweight dogs are more likely to develop them. Depending on where a lipoma is placed and whether or not it interferes with your dog’s mobility, your veterinarian may recommend either monitoring or removal. 

2. Skin tags and cysts 

Unless they become very large, skin tags and cysts are usually not harmful. Cysts can rupture and spill while dangling skin tags can get hooked, bleed, and hurt. In most cases, at-home monitoring is all that’s needed to manage these types of masses; but, if your pet starts to feel pain, your veterinarian may prescribe surgical removal. 

It is more common in middle-aged or older dogs to develop fatty tumour, particularly around the ribcage, but they can appear elsewhere. Age-related changes like this are accepted as a part of life. There are no breed restrictions when it comes to these conditions; however, larger dogs and those that are obese are more likely to develop them. 

3. Blood Clots (Hematomas)

When your dog is injured, a blood clot forms on the surface of his skin as a result of the injury. However, even if your dog’s hematoma appears to be painful, bloated and hard to the touch, it isn’t harmful to your pet. However, a doctor may need to examine the damage beneath the hematoma to ensure that no broken bones or other significant health issues have occurred. 

4. Abscesses 

An infection causes an abscess, which should be treated by a veterinarian as soon as possible. Despite the fact that these illnesses will make your dog’s skin hot and uncomfortable to the touch, they are not dangerous to your dog’s health if treated promptly. As a result, seek immediate care at a veterinary clinic or animal hospital. 

5. A tumour in the peritoneum 

Tumors in the sebaceous (oil) glands that surround the anus are known as perianal adenomas, and they are quite frequent. Unneutered male dogs are more likely to have these lumps, but spayed female dogs might get them as well. An adenomas of the perianal glands are slow-growing and non-painful, but they can become infected and ulcerated if they are exposed to the environment. 

6. Malignant tumors 

On the other hand, malignant tumours are usually firmer and less sensitive to the touch than lipomas. If the tumour turns out to be benign, your dog’s health will not be affected. In order to fully assess the tumour and establish whether further therapy is required, a biopsy must be performed. 

7. Melanoma 

Mutant dogs are more likely to develop canine melanoma tumours because melanocytes, pigment-carrying cells, proliferate out of control. If you see a tumour on your pet, consult your veterinarian right once to rule out anything serious. Non-sunlight-induced cutaneous melanomas are benign and manageable with surgery, but sun-induced melanomas are aggressive and tend to develop around the lips and on the legs. 

Soft Lumps on Dog Under Skin: What Should You Do? | Guide

Should I be worried if my dog has a soft lump under skin? 

A new lump on your dog is a cause for concern and worry for the majority of owners. Dog lumps are commonly linked to cancer, which is one of the most common human lump causes. You should also remember that dogs can develop a wide variety of lumps for a variety of causes, including some that are inherited and many others that represent no significant health risk to your dog. 

In spite of this, lumps aren’t to be ignored. Regardless of whether your dog got a lump on the spot or you’ve seen multiple lumps all over your dog’s body, it’s always better to be safe than sorry and get the affected regions checked out and prescribed the right therapy. To help you identify lumps on your dog, we’ve compiled a list of the most common forms, as well as how to treat them. 

Canine lipomas are the most frequent type of benign skin tumour, and they develop when fat cells build up in the area of the tumour. Some dogs are born without lipomas, while others develop several lumps as a result of the condition. You should avoid conflating lipoma with lymphoma due to the similarity in the two medical words. An AMC oncologist will most likely treat a dog with lymphoma, a cancer of the lymph nodes. 

Unlike tumours, lipomas aren’t linked to the underlying body wall and can be easily moved around the body. Some lipomas can grow to enormous sizes, covering the entire side of your dog, without causing any medical problems for your pet.

Lipomas cannot be detected by veterinarians based on how the skin mass appears or feels. As with a lipoma, malignant mast cell and soft tissue sarcoma tumours grow beneath the surface of the skin where they might feel mushy and soft. Dogs with ten lumps have nine lipomas and a severe mast cell tumour, which I’ve seen. 

Many dog families are concerned when they discover a lump on their pet, however the vast majority of lipomas are completely harmless to dogs. A lipoma can occasionally grow to enormous proportions to the point that it causes problems with ambulation. The removal of them, which are commonly located in the dog’s armpit, vastly enhances the dog’s quality of life. 

What to do if your dog has a lump under skin? 

When you discover a growth or lump on your pet, you may be terrified. However, most individuals automatically associate these symptoms with cancer. If your dog or cat gets a lump, you should do the following: 

1. Don’t be alarmed.  

Although seeing a lump on your pet can be frightening, try to remain calm and avoid jumping to conclusions. Many of the lumps detected on pets aren’t malignant; they’re benign growths. 

3. Take a caliper to the area to be measured.  

Once you’ve located a mass, keep an eye on it to see how big it gets. If a mass is expanding, surgery may be recommended to remove it. This depends on the mass’s growth rate, location, the patient’s health, and other factors. If you notice any lumps or bumps, we strongly advise that you consult with your primary veterinarian right away. 

4. Be on the lookout 

Keep a watch out for any new lumps on your dog, even if the one you found wasn’t cancerous. 

For pets with several lumps and bumps, your veterinarian may create a chart detailing their locations and sizes so that you know what’s new as well as what’s changed. 

This is something that anyone can do. When your dog is being groomed, a good opportunity to check on his overall health is presented. More familiarity with their physique means you’ll detect problems faster. 

5. Biopsy

In order to perform this type of diagnostic examination, anaesthesia or sedation is required, and a sample of the mass is removed and sent to a third-party laboratory for analysis. 

6. X-ray  

A chest X-ray, as well as an abdominal X-ray, may be performed if your pet has an unknown mass to screen for metastases (the spread of cancer cells to another part of the body).

Top 5 FAQs and answers related to Soft Lumps on Dog Under Skin 

What could be causing the soft lump on my dog’s chest? 

Lipoma. Fat-filled tumours known as lipomas are frequent in middle-aged and older dogs and are thought to be an inevitable byproduct of the dog’s ageing process. These circular, non-painful masses are soft and round, and they expand slowly. 

If I notice a bump on my dog, should I be concerned? 

When in doubt, take your dog to the vet for an examination. A vet visit should be scheduled as soon as you see any of these symptoms: rapid growth, redness or swelling, pus or a sore spot on the dog’s body. 

What to do about a soft bump under the dog’s skin? 

Surgical excision is the only way to get rid of lipomas for good. It’s preferable to get these lumps removed when they’re small because surgery is less invasive and your pet will have a smaller incision and feel less pain. 

How to know if the lump on your dog is cancerous? 

Unlike lipomas, which are soft and fatty, malignant tumours are stiff and hard to the touch, appearing as an immovable hard mass on your dog. 

Do canine lipomas go away on their own? 

A lipoma will usually either remain the same size or, more commonly, slowly develop in size over time. Most of the time, they don’t go away on their own accord. 


The development of lipomas in your dog is a normal aspect of ageing and there is nothing you can do to prevent it. 

As soon as you see any evidence of lipomas on your pet, call your veterinarian right away. Your dog’s health depends on how quickly you get him in to the veterinarian’s office or a 24-hour animal hospital. Once the veterinarians have determined what’s wrong with the lump, they may then determine what therapies are required to return your pet back to its normal range of motion and movement as quickly as possible.
