A dog is considered man’s best friend because it loves selflessly - It waits for you patiently every single day, wags its tail to show you it is happy, barks when strangers come near. It plants sloppy kisses all over you face and curls up beside you when you are low. It listens patiently when you need someone to talk to and follows every command of yours. A dog is so endearing that very few other animals can compare with it. It is thus rather unfortunate to know that cancer can occur even in these animals. You can treat your dog on time if you have information about dog cancer and its signs and symptoms and that is what this article endeavors to do, provide you with information so that you have many more happy memories with your pet.

Dog Lung Cancer - Types

Primary Lung Cancer - Tumors that originate in the lung are known as primary lung cancer. An x-ray taken of the chest shows these tumors as one large solitary mass. This type of dog lung cancer is rare but aggressive and can slowly metastasize to the regional lymph nodes found in the upper chest area.

Metastatic Lung Cancer - This kind of dog cancer begins off as cancer cells in different parts of the body like the mouth, thyroid gland and leg bone. Slowly the cells spread to the lungs through the bloodstream. Benign metastatic lung tumors may also be caused by fungal infections that occur in the rest of the body.

Dog Lung Cancer - Symptoms

Like most other diseases dog lung cancer also has no visible signs in the early stages, it is only once the cancer has progressed further that the symptoms appear and the disease becomes evident. The symptoms to watch out for are -

  • Lethargy
  • Loss of Weight
  • Loss of Appetite
  • Difficulty Breathing
  • Lameness
  • Chronic Cough (In the absence or presence of mucus/blood)

Dog Lung Cancer - Causes

The causes of the lung cancer in your dog may be different from the causes in another, but research conducted by veterinarians has shown that dog lung cancer can also occur because of the reasons listed below.

Passive smoke and its effects: Like humans, dogs are also sensitive to smoke. Too much exposure to smoke may play a role in the development of tumors in the lungs.

Urban Environment: Pure air is not only beneficial for humans but animals too. Studies have shown that dogs that are brought up in urban cities have a higher risk of developing cancer of the lungs.

Dog Lung Cancer - Diagnosis and Treatment

An x-ray is the first line of treatment the vet will follow if your dog shows signs of lung cancer. If a tumor is detected the vet may conduct a examination with a fine needle aspirate after which a biopsy of lung tissue may be done in order to confirm malignancy.

If your dog has primary lung cancer then surgery is the main treatment. Of course the surgery depends in the size and location of the tumor. Apart from surgery the vet may also recommend chemotherapy or radiation therapy in order to prevent the spread or re-growth of the cancerous tissues. On the other hand surgery is not an option considered in the case of metastatic canine lung cancer. This type of dog cancer is treated with radiation or chemotherapy. The prognosis of dog lung cancer may range from two months to two years. This time period depends on weather the cancer has spread to the other parts of the body.
