Dog Has Lump Left Side Rib Cage: Understanding the Risks

If your dog has a lump on the left side of their rib cage, it's essential to understand the potential risks involved. A lump in this area can be a sign of a serious health issue, such as a tumor or an infection.

The lump could be a symptom of a benign condition, but it's crucial to have it checked by a veterinarian to rule out any underlying problems. In some cases, a lump on the left side of the rib cage can be a sign of a more serious condition, such as a heart problem or a lung issue.

A veterinarian will typically perform a physical examination, take a complete medical history, and may conduct imaging tests, such as X-rays or an ultrasound, to determine the cause of the lump. The sooner you seek veterinary attention, the better chance your dog has of receiving proper treatment and making a full recovery.

Your veterinarian may also perform a fine-needle aspiration or biopsy to collect a sample of the lump for further examination.

Fat, tumors, cysts, and infections can all cause lumps and bumps on your dog. These can be serious or less serious.

A hernia occurs when one tissue or organ protrudes through another into an abnormal place on the body, often causing a lump or bump.

Your veterinarian may not be able to determine the type of lump just by feeling it, except in cases of allergic reactions and abscesses.

A hygroma in dogs is caused by repeated trauma, which can lead to an inflammatory response and the development of a soft, fluid-filled swelling. This swelling is typically found over pressure points, particularly on the arm and leg joints.

Lying on hard surfaces, such as pavement, can cause the repeated trauma that leads to hygroma. This is especially true for larger breeds of dogs, as they put more weight on their joints.

A hygroma is more likely to occur in dogs that are more sedentary, such as those recovering from surgery or in their elderly years. This is because they are not able to move around as much and put pressure on their joints.

Here are some common scenarios where hygroma is more likely to occur:

If you suspect your dog has a hygroma, it's essential to take them to the vet for proper diagnosis and treatment.

If you notice a palpable lump on your dog's chest, it could be a sign of rib osteosarcoma. The lump may not be noticeable at first, but it's essential to take your dog to the vet for examination if you notice any unusual symptoms.

Difficulty breathing is another common symptom, often caused by the tumor pressing on the lung. This can be a serious issue and requires immediate veterinary attention.

Lethargy is also a possible symptom of rib osteosarcoma in dogs. If your dog seems unusually tired or sluggish, it's crucial to have them checked out by a vet.

Lameness in the forelimbs is a common symptom if the tumor is located on the first four ribs. This can be a challenging condition to diagnose, but early detection is key to effective treatment.

The most common signs and symptoms of rib osteosarcoma in dogs include:

Your veterinarian will use several options to determine if the lump on your dog's left side rib cage is one that should be dealt with quickly or one that is unlikely to cause a problem.

Cytology is a test that can be completed in your veterinary clinic without sedation, where your veterinarian will aspirate the lump with a small needle and look at the sample under a microscope.

A local biopsy may be recommended if the lump is rapidly growing, which involves taking a small sample surgically and suturing the site. The sample will be submitted to an outside laboratory for evaluation by a veterinary pathologist.

Your veterinarian may also recommend full surgical excision, where the entire growth will be removed, ideally submitting the entire growth to a pathologist to identify the type of growth and whether it was able to be completely removed.

Here are the three diagnostic options your veterinarian may consider:

Diagnosis of Hygroma involves a physical examination by your veterinarian, who will ask about the timing and any changes in your dog's behavior.

Your veterinarian will want to know when you first noticed the swelling on your dog, as this information can be crucial in determining the best course of action.

A biopsy may be conducted to confirm the diagnosis, especially if the lesions look unusual.

The hygroma itself will appear as a sac separated from the skin, with a tough, dense wall and a fluid-filled interior that can range in color from yellow to red.

Before your vet can recommend a treatment for rib tumors, they'll need to run some tests to determine your dog's overall health and whether they're strong enough for surgery. These tests include preoperative blood work, urine tests, and chemistry profiles.

Your vet will want to know if your dog is healthy enough for surgery, as this will determine the best course of treatment. They'll work with you to determine the best approach for your dog's specific situation.

To prepare for surgery, your dog will need to be kept off food and given a dose of Pepcid AC. This will help reduce the risk of complications during the procedure.

Your vet will prescribe pain medication for use during and after surgery, which may include general anesthesia, analgesics, and anti-inflammatory medicines.

The goal of surgery is to remove the tumor, and your vet will work with you to determine the best approach.

Your vet will likely perform a Fine Needle Aspiration (FNA) to identify the cause of the lump, which is the most common test used to diagnose lumps on dogs.

Some common causes of lumps and bumps on dogs include fat, tumors, cysts, infection, allergic reactions, and swelling from injury or hernia. A hernia occurs when one tissue or organ protrudes through another into an abnormal place on the body, often causing a lump or bump.

Lumps can be difficult to identify just by feeling them, and even benign growths can slowly grow and become troublesome to your pet. Your veterinarian may recommend periodic checks to monitor the size of the lump.

Here are some common tests used to diagnose lumps on dogs:

A hygroma is a soft subcutaneous swelling filled with fluid that can develop on the olecranon of the elbow, and can grow to two inches in diameter. If the hygroma has been present for a significant length of time, it may become infected, leading to symptoms such as ulceration, infection, abscesses, granulomas, fistulas, and tissue erosion.

A hygroma in your dog can be a bit of a mystery at first, but knowing the symptoms can help you identify the issue early on.

You might notice a soft subcutaneous swelling filled with fluid, which can be yellow to red in color, over a pressure point or bony prominence.

Hygromas can vary in size, but they can grow up to two inches in diameter.

They're often developed on the olecranon of the elbow, which is a bony prominence.

In some cases, hygromas can be bilateral, meaning they occur on both sides of the body.

If left untreated, hygromas can lead to severe inflammation, which can cause a range of complications.

Here are some potential complications to look out for:

If a hygroma becomes infected, it may become painful and warm to the touch.

Hygromas don't always need treatment, and in some cases, simply monitoring them is enough. Your vet will discuss the best course of action with you.

For small hygromas, protective padding can help resolve the issue. This involves bandaging the area and providing soft bedding to prevent further trauma.

In some cases, aseptic needle aspiration and corrective housing are recommended to treat hygromas. This can lead to a protective callus forming after about three weeks.

If your dog has chronic hygromas, surgical drainage, flushing, and Penrose drains may be necessary. This can help dry out the lesions, and bandages can be removed after six weeks.

Laser therapy can be used to treat small hygromas, and in severe cases, extensive drainage, surgical removal, or skin grafts may be required.

Lipomas or Fatty Growths are commonly thought of as a part of the aging process for dogs.

They are benign tumors that are just a mass of fat cells under normal skin, usually soft, round, and movable.

Lipomas are often found around the ribs, but they can show up in other places on the body as well.

Middle-aged to senior dogs who lean toward being overweight are more likely to develop lipomas.

You don't need to worry about lipomas on your dog, as they are slow-growing and shouldn't cause any discomfort.

However, your vet will ask you to monitor the growth and if it affects your dog's day-to-day life.

If it grows quickly, or to a point where your dog starts to have to work around it, it can be removed.

Or, it can be removed when it's diagnosed, as well.

An abscess is a swelling caused by pus building up under the skin, often as a result of an infection or insect bite. It can develop quickly and become painful for your dog if not treated promptly.

Abscesses are usually accompanied by redness, swelling, and warmth around the affected area. They may also cause your dog to lick or chew at the affected area excessively.

While abscesses can be painful and concerning, most of the time they can be taken care of with a vet visit to drain the pus safely and prescribe antibiotics to prevent the infection from returning or spreading.

If left untreated, abscesses can lead to more serious health issues, so it's essential to seek veterinary attention as soon as possible.

Here are some common signs of an abscess:

If you suspect your dog has an abscess, don't hesitate to contact your veterinarian for guidance and treatment.

Mast cell tumors are the most common form of skin cancer in dogs. They can have many different looks depending on where, how, and when they develop on your dog. They can be both over the dog's skin—where you would be able to see it past their fur—or under, hidden by their fur. They usually feel solid and firm to the touch and can be irregularly shaped, rather than the expected rounded bump.

Your vet will likely recommend a surgical removal of the affected tissue as well as a small border layer around it to make sure that all of the cancerous cells are removed. When caught early, this process is very effective and your pup will be back on the move in no time.

Mast cell tumors need professional treatment, so it's essential to have them checked out by a vet as soon as possible. Early detection is key to successful treatment.

Some common signs of mast cell tumors include:

If you suspect your dog has a mast cell tumor, don't hesitate to contact your vet for advice and guidance.

Your veterinarian has several options to determine if a lump is one that should be dealt with quickly or one that is unlikely to cause a problem.

Cytology is a test that can be completed in a veterinary clinic and usually doesn't require sedation. It involves aspirating the lump several times with a small needle and looking at the sample under a microscope.

Fine Needle Aspiration (FNA) is a common test used to identify what's causing a lump. Your vet will take a small, unintrusive needle and stick the bump to get a sample of cells.

A biopsy may be recommended if the FNA is unable to identify what's causing the lump. This involves sedating your dog, taking a part of the lump, or all of it if it's small, and examining it closely by a laboratory.

Full surgical excision is an option for removing the entire growth. Your veterinarian will completely anesthetize your pet and remove the entire growth, ideally submitting it to a pathologist to identify the type of growth and whether it was able to be completely removed.

Any lump or bump, new or old, big or small, should always be evaluated by your veterinarian. It's a good habit to periodically check the size of a benign growth, as it can slowly grow and ultimately need to be removed.

Here are the options your veterinarian may consider when treating and diagnosing lumps and bumps:

If your vet suspects the lump is cancerous, they'll use a Fine Needle Aspiration (FNA) to take a sample of cells from the lump. This is usually done without sedation, and the sample is then examined under a microscope to determine if there are any cancerous properties.

A majority of lumps on dogs are diagnosed with an FNA, which is a good thing because it's a relatively quick and non-intrusive test. Your vet will use the information from the FNA to identify the type of lump and determine the best course of action.

If the FNA is unable to identify what's causing the lump, your vet may sedate your dog to take a biopsy of the lump. A biopsy will require a part of the lump to be removed and examined closely by a laboratory.

In some cases, the lump may have fluid inside, which makes it difficult to use an FNA. In these instances, the fluid is extracted and sent to a lab for closer inspection on a molecular level to determine what it is.

Your vet will use the results of these tests to come up with the best plan of action. This may involve simply keeping an eye on the size of the lump, or it may require antibiotics or surgical removal.

Here are the common tests your vet may use to diagnose a lump on your dog:

Even if your vet determines the lump is benign, it's still a good idea to periodically check the size to ensure it's not growing or becoming troublesome for your pet.
