Purrfect Pet CoQ10 can increase tissue oxygenation and help to ease lung inflammation. Purrfect Pet is made with genuine Kaneka Ubiquinol™, the reduced, active antioxidant form of coenzyme Q10. Ubiquinol is up to 8 times more absorbable than conventional coenzyme Q10 making the efficacy superior to other products with standard CoQ10 - backed by over 18 clinical studies. Experts recommend CoQ10 for lung health supplementation.


"My dog Marco was diagnosed with inoperable lung cancer. I used a number of immune support supplements from Ask Ariel such as Resveratrol for Dogs, Curcumin For Pets, Amazing Omegas, Immune Harmony, Power Probiotic and a few others. One of his symptoms prior to using the supplements was his constant coughing. We previously had tried some coughing medication from the veterinarian and Marco was still coughing. But after using the supplements, his coughing improved so much. Thank you so much for helping Marco feel better!" - Karen, California

What Is Lung Cancer In Dogs?

The lungs are a vital part of your dog's respiratory system, responsible for supplying oxygen to the body's cells and removing waste gases like carbon dioxide. When the lungs are compromised, your dog may not get enough oxygen, which can affect the heart, brain, and overall health. Breathing problems in dogs can be due to various factors, including excess weight, allergies, chronic bronchitis, heart disease, or lung cancer.

Lung cancer in dogs often involves the abnormal growth of epithelial (skin) cells in the lung tissue. The most common type, adenocarcinoma, accounts for 75% of canine lung cancer cases. This fast-growing, malignant cancer can quickly spread to other body parts, including the lymph nodes and brain. Lung cancer is typically found in older dogs, with certain breeds like Boxers being more predisposed. While the exact cause is unknown, long-term exposure to toxins such as second-hand smoke and toxic cleaning agents may increase the risk.

Types of Lung Cancer in Dogs

Lung cancer in dogs can be classified into two main types: primary and metastatic.

Primary Lung Cancer - This type originates in the lung tissue itself and is quite rare, making up only about 1% of all canine cancers. The most common form of primary lung cancer is carcinoma. Adenocarcinoma accounts for approximately 75% of cases. These tumors can grow rapidly and metastasize to other organs, bones, and lymph nodes. Breeds like Boxers, Doberman Pinschers, Australian Shepherds, Bernese Mountain Dogs, and Irish Setters are more prone to developing primary lung tumors.

Metastatic Lung Cancer - This form is more common and occurs when cancer spreads to the lungs from other parts of the body via the blood or lymphatic system. Common cancers that metastasize to the lungs include osteosarcoma and lymphoma. Metastatic lung cancer usually presents with symptoms similar to primary lung cancer, though coughing is less common. These tumors often appear as multiple masses, and unfortunately, many metastatic tumors are too small to be detected on x-rays, often not visible until late in the disease's progression.

Symptoms of Lung Cancer in Dogs

Some of the most common clinical symptoms of lung cancer are listed below. With many types of cancer, a pet will not show any outward signs that they are not feeling well. Subtle changes to appetite, mood and activity may signal that your dog does not feel well. Symptoms of lung cancer may include:

  • Coughing
  • Dyspnea (difficulty breathing)
  • Tachypnea (rapid breathing)
  • Exercise intolerance, low energy level and lethargy
  • Poor appetite and gradual weight loss

Some dogs with lung tumors may cough up blood (hemoptysis), have fever or pain, start to exhibit muscle wasting or have an accumulation of fluid in the abdomen (ascites). Using natural vitamins for lung cancer in dogs can help to make your pet more comfortable by supporting lung function and reducing inflammation.

How Is Dog Lung Cancer Diagnosed?

Since many dogs with lung cancer have no symptoms, tumors are often found when a dog is undergoing routine diagnostic testing, such as blood work, urinalysis, or x-rays, for an unrelated condition. Testing for lung cancer may include:

  • Chest x-ray
  • Blood work & urinalysis
  • Ultrasound or CT scan
  • Biopsy

Complete diagnostic testing can help your vet or veterinary oncologist have a clearer picture of how much lung tissue has been affected by the cancer and can help to determine what treatment options may be helpful for your dog.

Treatment Options For Dog Lung Tumors

Surgery to remove the lung tumor and surrounding lung tissue or lung lobe is the recommended conventional veterinary treatment in most cases. If the tumors have spread to multiple lung lobes or the lymph nodes, chemotherapy is generally suggested as an alternative to surgery. Radiation therapy may also be used.

Holistic treatments for dog lung cancer can be combined with most conventional veterinary options. Adding natural immune support supplements, such as medicinal mushrooms, curcumin, CoQ10 and fish oil, can help your dog to breathe better and feel more comfortable. Simple diet changes can help to improve digestion and fight inflammation. At Ask Ariel, we will include FREE dog lung cancer diet tips on the packing slip that comes with your order.

How Long Can A Dog Live With Lung Cancer?

The life expectancy of a dog with lung cancer varies depending on the type of cancer and the treatments selected. A dog that has a primary lung tumor (or tumors) removed can live an average of 12-16 months if the cancer has not spread to the lymph nodes. If the cancer has spread through the lymphatic system, the prognosis decreases to an average life expectancy of 2 months. Whether your dog has surgery or not, supportive care using a dog lung cancer diet and holistic cancer supplements for dogs can improve the quality of life for your pet and, often, the quantity of time as well.


"Our 13 year old dog Legend has lung scarring which can cause him to breathe and pant very heavily, especially after exercise. We saw a noticeable improvement in his breathing and stamina when we started using Purrfect Pet CoQ10 twice a day. The product seems to help him stay energized and to avoid gasping. It even helped to reduce his snoring!" - Davis Family, California

Lifestyle Changes Can Help Dogs With Lung Cancer

A comprehensive approach to treating lung cancer will provide the most relief for your dog. Check with your veterinarian or oncologist about combining natural supplements with any medications and treatments (radiation or chemotherapy) prescribed by them. Using holistic vitamins in combination with diet changes can help strengthen your dog's immune system. A few lifestyle changes can also help to lessen the severity of some lung cancer symptoms:

Maintain a healthy weight. When your pet becomes overweight, it takes more energy to breathe. This pressure in the lungs can aggravate the inflamed tissue and cause coughing and difficulty breathing. Substituting green vegetables for some of the food in your dog's meals is an excellent way to help your dog lose weight. They help your pet feel more satisfied and offer a low-calorie, nutritious source of bulk food. Long, slow walks are very helpful for pets with lung cancer. They help to keep your dog active and may help to prevent lethargy and muscle wasting.

Avoid airborne irritants. Cigarette smoke, dust, and strong fragrances can promote coughing. As with people, second-hand exposure to cigarette smoke has also been linked to the development of lung tumors in dogs. Dogs living inside homes with smokers have a 60% risk for developing lung cancer. Another possible risk factor is living in environments high in pollutants. Brachycephalic breeds with their flat noses are also at greater risk, due to less filtering in their nasal passages. By keeping the windows closed and by running an air conditioner or air purifier, you can minimize respiratory distress.

The Best Diet For Dogs With Lung Cancer

Lung cancer in dogs holistic treatment includes not only supplements, but diet changes as well. Dogs with lung cancer can benefit from a low-carbohydrate, hypoallergenic diet, rich in Omega-3 fatty acids. Research studies have shown that eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), two types of omega-3 fatty acids, can help slow the development of tumors and metastases of certain cancers. By using a high-quality fish oil and adding a small portion of baked fish or sardines in water can provide a source of omega-3s in your dog's diet.

Diets high in carbohydrates may promote tumor growth and should be controlled. Dry food diets generally are high in carbohydrates so choosing another form of dog food such as raw frozen, canned or homemade can be beneficial. Adding an array of fresh vegetables can provide important enzymes and nutrients to your dog's diet. Since the majority of your dog's immune system resides in the intestinal tract, maintaining a balanced microbiome is also essential. Probiotics along with fresh foods containing prebiotic fibers can support a healthy immune system.

While we no longer offer consultations, we do include FREE dog lung cancer diet tips on the packing slip that comes with your order.
