Mesothelioma In Dogs: Insights into Diagnosis and Management

Mesothelioma in dogs is a serious health issue, even though it’s rare.

The causes are still being studied, but knowing which breeds are more prone, recognizing symptoms, and knowing how to manage them is important for pet owners.

Finding it early and getting help from a vet quickly is key to keeping affected dogs comfortable and their quality of life as good as possible. 


Mesothelioma in Dogs: A Guide to Understanding and Managing This Rare Cancer

Mesothelioma, a rare and aggressive cancer, grows in the mesothelioma, a thin tissue layer lining body cavities

It’s mostly linked to asbestos exposure in humans but can also affect dogs, worrying pet owners.

This article explores mesothelioma in dogs, covering breeds at risk, detection, symptoms, its impact on animals, and how to manage it.

Breeds Susceptible to Mesothelioma

  • German Shepherd Dogs: This breed statistically exhibits a higher incidence of mesothelioma compared to others.
  • Rottweilers: Another breed showing a higher risk of developing this cancer.
  • Golden Retrievers: While less common than the aforementioned breeds, Golden Retrievers have also been diagnosed with mesothelioma.
  • Other Breeds: While less frequent, mesothelioma has been reported in various other dog breeds, highlighting the potential for any dog to be affected.

Detection of Mesothelioma in Dogs

Clinical Signs: You might notice symptoms like trouble breathing, fluid buildup in the abdomen or chest, and weight loss.

Imaging Tests: X-rays, ultrasounds, and CT scans can show any problems linked to the disease.

Cytology: Looking at fluid samples from the affected areas might show abnormal cells.

Biopsy: This test gets a tissue sample from the suspected tumor and looks at it under a microscope to check for cancer cells.

Mesothelioma In Dogs: Visible Symptoms in Canines

Respiratory difficulties: Dogs may cough, have trouble breathing, or tire quickly.

Abnormal fluid buildup: Dogs might get fluid in their belly (as cited) or chest (pleural effusion).

Lethargy and fatigue: Dogs with mesothelioma might seem tired and less active.

Weight loss: They might struggle to eat or keep weight due to the disease.

Loss of appetite: Not eating could show they’re uncomfortable or in pain.

Susceptibility in Other Animals

While people and dogs are mainly linked to mesothelioma, it’s been seen in other animals too:

Cats: They rarely get mesothelioma, but there have been cases.

Rats and mice: In labs, they might get it from being around asbestos.

Horses and cattle: They can get it too, but it’s very uncommon.

Management Strategies Of Mesothelioma In Dogs

Unfortunately, there’s no cure for mesothelioma in dogs because it’s very aggressive. But there are ways to help them feel better:

Palliative care: This focuses on easing symptoms like pain and fluid buildup to make them more comfortable. Medicine, changes in diet, and supportive care are important.

Surgery: Sometimes, they can remove the tumor with surgery, especially if it hasn’t spread much.

Chemotherapy: They might use this to slow down the tumor growth and manage symptoms, even though it might not cure it.

Isolation of Affected Dogs

Mesothelioma in dogs can’t spread to other dogs or people just by being around them. So, you don’t need to keep an affected dog separate for safety reasons. But it’s important to keep things clean by washing your hands after touching the dog or its stuff. This helps stop other germs from spreading.

Potential Causes of Mesothelioma in Dogs

Asbestos exposure: While asbestos exposure is known to cause mesothelioma in humans, its role in canine cases isn’t fully understood.

Some studies hint at potential environmental exposure, but the link isn’t as clear in dogs.

Genetic predisposition: Some breeds might have genes that make them more likely to get mesothelioma because of how their cells grow and regulate.

Environmental factors: Other toxins or irritants in the environment could also play a part, but more research is needed to be sure.

Viral infections: There might be a link between certain viral infections and mesothelioma in dogs, but we need to learn more about it.

Mesothelioma In Dogs: Additional Risk Factors

Age: Older dogs have a higher chance of getting mesothelioma than younger ones.

Sex: Some studies show that male dogs might have a bit more mesothelioma than females, but we’re not sure why.

Previous injuries: If a dog had lung or chest injuries before, it might affect how their cells grow and cause mesothelioma.

Owners’ jobs: People who work with asbestos might bring it home, which could raise their dog’s risk, but we don’t have much proof of this.

Mesothelioma In Dogs: Prognosis and Challenges

Stage of the disease: Finding mesothelioma early gives a bit better chance to manage it and make life last longer.

Location and size of the tumor: If the tumor is only in one spot, there might be more ways to treat it than if it’s spread out.

Dog’s health: How healthy the dog is and how well their immune system works can affect how they respond to treatment and how long they live.
