Causes Of Bumps In Pets

Skin Lumps and Bumps in Dogs: What a Lump on Your Dog’s Skin Can Mean

Bumps in pets tend to fall into one of the following categories:

  • An infection or abscess
  • A reaction to something foreign in the body
  • A harmless growth such as a skin tag, cyst, or warty growth

In many cases, a new growth on your pet can be looked at by your veterinarian at your pets next appointment. Some, however, warrant more immediate attention. Give us a call if your pets bump meets any of the following criteria:

  • The area is painful to the touch or when your pet moves, especially any bumps located in the groin or armpit
  • The bump is noticeably growing or changing over the course of a month or less
  • There is discharge, bleeding, redness, or swelling in the area
  • Your pet has been previously diagnosed with cancer
  • Your pet is a short-haired breed prone to cancer
  • Your pet is 7 years old or older
  • All lumps and bumps on cats should be investigated by a veterinarian

Several bumps that appear out of nowhere and increase in size rapidly may indicate an allergic reaction. Seek emergency medical care for your pet immediately.

How Vets Diagnose Dog Lipomas

Because lipomas in dogs can appear and feel similar to other dangerous and malignant tumors, it is essential to get an accurate diagnosis of the mass.

Your veterinarian may recommend a noninvasive test known as a fine-needle aspirate and cytology exam. This is a diagnostic procedure where a needle is inserted into the mass for a sampling of cells.

The veterinarian will then stain the cells on a microscope slide and examine them under the microscope. This is a quick and safe test.

Typically, lipomas have oily material and fat cells that are easy to identify under the microscope. Taking a biopsy with a larger tissue size is essential to confirm that the mass is a lipoma, as it allows for a much more comprehensive examination of the mass.

Sometimes these fatty tumors turn out to be malignant lipomas , even though they look and feel like their benign counterparts.

See Something Do Something

See Something Do Something is a set of guidelines I am developing with my colleagues at VCA Hospitals to help guardians and veterinarians figure out what to do when they find lumps on dogs skin, or just under the skin.

See Something: When a skin lump is the size of pea or larger or has been present for one month,

Do Something:Aspirate or biopsy, and treat appropriately.

A pea is about one centimeter, or about half the diameter of a penny. Why so small? When masses are removed early, the prognosis can be excellent, with no additional treatment needed after surgery.

But to limit the number or surgeries, we must get a diagnosis with cytology or biopsy early and before removing a tumor. This will lead to an improved outcome for your pet. A single surgical procedure can cure your pet for the majority of tumors. This is especially true for benign tumors, and some cancers that are only locally invasive .

First Thing First: Dont Panic

Lumps and bumps pop up on dogs for a variety of reasons, many of which are of little threat to your dogs life. The bump could be an abscess secondary to a bite, an inflamed hair follicle, a benign fatty growth, or a more serious condition, like cancer.

Finding a lump on a dog does not necessarily mean the worst, but it is important for a veterinarian to evaluate it to ensure a proper diagnosis is obtained and a treatment plan is initiated if necessary.

In most cases, it is appropriate to schedule an appointment that is convenient for you, such as your next day off work. However, if the lump or bump is hot to touch, growing quickly, producing pus or discharge, actively bleeding, or if your dog is in pain, you should take your dog to an emergency veterinary hospital for more urgent care.

Why Do Sudden Lumps On Dog Occur

My 6.5 year old 68

The majority of dog lumps are non-cancerous, meaning they are not malignant. Many different things might cause this sudden lump on the dogs nose. They could be fatty deposits in the skin or a fatty tumor. In elderly dogs, fatty tumors are prevalent and may cause abrupt lumps on your pets body. Fatty tumors are often tender to the touch, although dogs seldom show signs of discomfort from these benign tumors. Lumpy warts dont need to be treated unless they cause your pet any discomfort or discomfort.

Warts are not hazardous, but they may get infected and cause skin irritation, so its vital to watch them and treat them when necessary. Bacterial infection may cause a bacterial abscess, an accumulation of puss inside the body. They generally start as tiny bumps beneath the skin and progress into more severe infections.

Lumps On Dogs: Types And What They Mean

Finding a lump or bump on your dog is likely to trigger a wave of fear and anxiety, especially if it suddenly sprouts out of nowhere. More often than not, our minds immediately jump to the worst scenario: my dog has cancer.

Fortunately, less than half of lumps on dogs are malignant, or cancerous, and most are treatable. In fact, lumps on or below the skin are the most common masses reported in dogs, representing roughly one third of all tumors.

Most lumps on dogs look or feel similar regardless of whether or not they are cancerous, so its crucial to have it checked by your veterinarian to know for sure. While a quick Google search may be tempting, its easy to misdiagnose your pets lump and subsequently delay the care they actually need. Early intervention can prevent unnecessary discomfort and potentially save them from serious, life-threatening consequences.

Lets explore some of the lumps and bumps that are common on dogs, their characteristics, and what they mean for a dogs overall health and longevity.

What Causes Dog Lipomas

Veterinary science still isnt exactly sure. Its unclear why some dogs go their whole life without a lipoma, yet others find themselves particularly prone to these benign little lumps.

That being said, science has helped us identify a couple risk factors:

Certain breeds are more likely to develop lipomas, while others see them less frequently.

Types Of Lumps And Bumps On Dogs

You can find many different types of lumps on dogs, but a few are more common:

  • A lipoma is a harmless or benign fatty tumor that is usually soft and can be fairly easily moved around. While lipomas are relatively slow-growing and dont usually pose a health threat to your pet, they need to be monitored for change in size so that they dont limit your pets mobility.
  • A sebaceous cyst is caused by a blocked oil gland or hair follicle, and is usually harmless to your pet. They are generally whitish in color, and are basically very large pimples. They may resolve on their own If left alone, but may need to be removed if an infection or inflammation occurs.
  • A mast cell tumor is a cancerous tumor most commonly found in the skin and subcutaneous tissue. Unfortunately, mast cell tumors dont have a typical look and feel. They may be big or small, soft or hard, flat or raised.

Are There Vaccines For Lumps On The Back Of Dogs

The dog has a painless lump under the skin of the neck

This is a common question that people ask us thinking that the balls in the bodies of dogs are produced by a single cause, but it is not so. The lumps, either because they are a tumor, as a result of a wound, a wart, or because they are a lump of fat do not have preventive treatment.

Whenever a lump appears in the body of your dog you have to document it, because that will give clues to your veterinarian to know what it is about. In the event that this lump is a wart, think that these have appeared because of the papillomavirus and removing it will not prevent them from having more, because the virus will continue like this.

Both in the case of these warts and other lumps or balls that may appear on the skin of your dog, as long as it is not a tumor, there is no need to intervene. Only if your dog begins to lick it until it irritates him, it is recommended to go to the vet to determine what it is and proceed to its removal. Dogs can make the rubbing of a lump a compulsion, and this can irritate it and cause an infection. Anyway, to confirm that it is not a tumor, it is best to go to a specialist.

We hope that this article has helped you to know that, not always the lump that moves on your dog is something serious. To solve your doubts, take a picture and make a consultation with our online veterinarians.

Common Masses Found On Pets

Benign tumors

  • Lipomas are the most common masses found on pets. These fatty tumors are almost always benign growths, and are usually just under the skin. They remain relatively mobile unless they invade local muscle and connective tissue. They are generally soft growths, but may become firm if they grow under a muscle layer. Lipomas are usually left alone, except for monitoring their growth. If they grow quickly, or they are located where they may restrict normal range of motion, such as behind an elbow, surgical removal may be recommended.
  • Histiocytomas are an abnormal growth of immune cells in the skin, and are often seen on young dogs. These masses can look angry, because of their bright red color and bubbled surface. They often appear overnight and sometimes will disappear without treatment. Some dogs may chew or bump these masses and make them bleed. If the tumor does not resolve itself or is bothering your pet, surgical removal may be recommended after speaking with your veterinarian.
  • Skin tags or cysts are generally benign, unless they grow large. Dangling skin tags can get caught, bleed, and cause pain, while cysts can rupture and ooze. Generally for these types of masses, at-home monitoring is the only treatment necessary, however, if your pet becomes uncomfortable, surgical removal may be recommended by your veterinarian.

    What Else Should I Look Out For When Checking My Dog

    Sores and Wounds that Wont Heal

    Sores and wounds that persistently dont heal with time could be a sign of multiple health issues including immune system problems, other infections, or cancer. Some cancers can look like open or non-healing sores.

    Significant Weight Loss

    If your dog has lost a lot of weight and theyre not on a diet, its time to get them checked out. Even if they dont have cancer, it could be an indication of another health problem.

    Chronic Vomiting or Diarrhoea

    This is another sign that could indicate various health problems, but is also synonymous with gastrointestinal cancers. Have your dog checked out immediately if they are regularly vomiting or have diarrhoea often.

    Weakness and Lethargy

    Weakness, lethargy and generally not acting like themselves is a sign of cancer, but also an indication of various other ailments, particularly in older dogs. If you notice that your dog is weaker or more lethargic than usual, it might be time for a visit to the vets.

    But, if the lumps listed above are not examined and assessed by a vet early on, they could develop into something more troublesome for your dog.

    Cancerous growths can be either malignant or benign. If a lump is benign, it tends to only appear in one place and not spread to other parts of the body, although it can become very large. Malignant growths tend to spread quickly and to other body parts .

    There’s a LUMP on Your Dog’s NECK – ¿Why?

    The only way to identify a lump with certainty is with a visit to the vet.

    Most vets will start with a fine needle aspiration as shown in the link. This will be able to immediately identify a lipoma or cyst.

    Other tumours require further testing. Here we have three choices:

  • Send the slide of aspirated material to a pathologist. This can be diagnostic but is unreliable as the tissue architecture has been lost.
  • Schedule an incisional biopsy, where we only take a small piece and get it analysed. This is the best way as it allows us to plan for a single curative surgery.
  • Schedule an excisional biopsy, where we remove the entire mass and get it analysed. Without a wide margin, this will only be curative for very benign lumps and require a second surgery for most others.
  • The decision we take will depend on many factors. Here are some thoughts we may have:

    • Its always good to send the slide, but the extra cost might not be justified by its unreliability
    • An excisional biopsy is never a good idea without analysis unless the vet is certain the lump is benign, or there is plenty of loose tissue for a second surgery
    • An incisional biopsy followed by definitive surgery will usually give the highest total cost
