Lung Cancer in Dogs

Face it. No one is ever ready to hear that their pet has lung cancer. This devastating fact will leave you confused and having many questions.

Lung cancer in dogs is extremely aggressive. If the cancer actually spreads, radiotherapy and chemotherapy will have to be used.

Here’s the good news: if lung cancer dogs is caught early, it sometimes can be treated with an operation alone.

There also has been a ton of mounting proof as to how CBD (cannabidiol) may be an efficient alternative for managing dogs that have lung cancer.

If you’ve recently faced the news that your pup has lung cancer, below we list some facts on lung cancer in canines and some suggestions about how CBD might have the ability to help.


Why Has My Pet Developed Lung Cancer?

Dog lung cancer falls into 2 types. Primary lung cancer is a cancer which has originated inside the lungs. Metastatic lung cancer is a cancer that has spread to the lungs from an additional body part. Of these two, metastatic lung cancer is the most typical in dogs. There are several other kinds of cancers which oftentimes quickly spread to the lungs from an additional body part.


The reasons why a canine develops lung cancer never are straightforward. Researchers know that cancer is damage to the cells that is caused by mutations, yet they don’t completely know what triggers this mutation.


In the instance of primary lung cancer, hereditary factors do play a part in a dog’s likelihood of developing this disease. Environmental factors, like chemical exposure and second-hand tobacco smoke exposure, additionally plays a factor.


Statistics prove clearly that canines who reside in a house in which someone smokes will have a 60 percent risk of developing cancer in the lungs.  Like human beings, second-hand smoke is a substantial risk factor.


The breed is also a risk factor. Dogs that have small or mid-sized snouts are more susceptible to developing lung cancer than the ones that have long snouts. That’s because the nasal cavity of a canine that has a shorter snout is less effective at filtering carcinogens out.


What are the Symptoms and Signs of Dog Lung Cancer? 

The symptoms of lung cancer in dogs will show will depend upon the kind of cancer. It’ll also depend upon whether the cancer also exists in other body parts. If the type of cancer is metastatic lung cancer, there’ll be other symptoms that are caused by the primary cancer that’s present somewhere else in the animal’s body.


Within the early dog lung cancer stages, there might not be any noticeable symptoms whatsoever. The first indications that there’s an issue might be a loss of weight and a lack of energy. If dog lung cancer is detected early enough, it greatly can improve the dog’s opportunity of survival, so it’s extremely important that you have the dog checked out as soon as any of these symptoms appear.


Below we list the most common lung cancer in dog symptoms:


  • Fever
  • Wasting of the muscles
  • Shortness of breath
  • Weakness and lethargy
  • Excessive sneezing
  • Breathing difficulties
  • Coughing blood
  • Signs of blood in the urine or stools
  • Weight loss
  • Unwillingness to exercise
  • Loss of appetite
  • Coughing


The most typical of all of these symptoms is coughing. A cough is going to be persistent, and it’ll be unproductive. There also is likely to be blood inside the mucus that’s generated with a cough.


What Are the Dog Lung Cancer Stages? 

The majority of dog lung cancers are metastatic lung cancers. Primary cancer is very rare. The following four dog lung cancer stages are as follows:


Stage One

Primary dog lung cancer is very aggressive. Spotting the early indications of the disease is extremely important. In stage one, the canines will have developed a tiny tumor. The tumor won’t have metastasized to any additional body organ or any tissue nearby. The first indications of stage 1 dog cancer are a loss of appetite, coughing, and potentially some coughing of blood. During this stage, the tumor may be surgically removed.


Stage Two 

In stage two of dog lung cancer, there’ll be multiple tumors present. The tumors are going to be 5 centimeters long or less and they’ll cause breathing difficulties, as well as more noticeable coughing. During this stage, surgery still is an option, yet there also will have to be follow-up chemotherapy, too.


Stage Three

At the third stage of the disease, multiple tumors are going to be present inside the lungs. Most of them are going to be larger than five centimeters. Nearby tissues and blood vessels also will have been affected by tumors. The symptoms that are displayed by the pet during this stage will involve coughing blood and breathing difficulties. At the third stage of dog lung cancer, surgery isn’t any longer an option, yet chemotherapy might be utilized to prevent the more spread of the cancer. A lung transplant might be recommended; however, it’s a high-risk surgical treatment that isn’t always a success.


Stage Four 

Sadly, during the fourth stage, the dog is going to be very sick indeed, and the veterinarian will probably suggest pet euthanasia. The dog’s tumor will have spread to the bones, lymph nodes, blood vessels, and chest. Now the pet is probably suffering considerable discomfort and pain.


If left neglected, dog lung cancer will spread to other body parts in two to ten months. But, if the tumors are detected, as well as removed early enough, a full remission is probable.


X-rays: Why are they Important? 

X-rays are the primary tool utilized for diagnosing dog lung cancer. The vet will utilize X-rays of a canine’s chest to identify the existence of tumors, as well as check for the existence of fluid inside the chest. A vet also may utilize abdominal X-rays to assess other dog body organs for proof that the cancer spread.


Within some instances, a vet might suggest a CT scan, either in addition to the X-rays or instead of them. That’s because CT scans may offer in-depth images that will permit a doctor to accurately ascertain the location and size of tumors.


Dog Lung Cancer – What are the Available Treatments?

Once the dog is diagnosed with lung cancer, it’s likely that the veterinarian will refer the pup to a vet oncologist. There are 3 primary treatments for dog lung cancer, which are radiotherapy, chemotherapy, and surgery.


The treatments selected for your pet will depend upon the size of the tumors, the location, extent of metastasis, as well as the cancer stage. Other crucial factors include the dog’s age and overall health.


CBD and Lung Cancer in Canines 

There’s growing evidence in studies that suggests that CBD oil might have pain and cancer-reducing properties, as well as the capability of managing other cancer symptoms like loss of appetite and nausea. Additionally, research has proven that CBD may offer a kinder cancer treatment than radiotherapy and chemotherapy.


A CBD lung cancer study that was published inside the Biochemical Pharmacology Journal by a German research group reviewed the effect that cannabinoids have upon lung cancer cells. The scientists discovered that CBD seems to make cancer cells more vulnerable to attack by the immune system of the body.


It’s vital that you know that cannabidiol, or CBD, is non-psychoactive. It is a natural compound that is found inside hemp plants. It stimulates the endocannabinoid system in animals and humans alike, which may have a wide array of beneficial effects and will not make your pet “high”.


Most dog owners have testified as to the efficiency of CBD for dogs with cancer to relieve the cancer symptoms in dog. In addition, its capability of reducing the impact of the side effects of treatments such as chemotherapy and radiotherapy. It also is broadly accepted by several specialists to have possible pain-reducing properties.


Even though not many veterinarians would advise that you utilize CBD Oil lung cancer as an alternative to the present lung cancer treatments, there’s growing anecdotal and clinical proof that CBD may manage the cancer symptoms, decrease pain, lower the side effects of cancer treatments, as well as potentially slow the spread and growth of cancer.


Scientific Studies and Research on Lung Cancer and CBD 

Below is a list of research concerning CBD and its potential for usage in dog lung cancer treatment. Note that the majority of the research involve experimental molecules, cannabinoid molecules, test tubes, and occasionally human cell-lined research. It is vital that you know that all mammals, which includes cats, dogs, elephants, rats, and human beings have cannabinoid receptors that all work in precisely the same way inside our Endocannabinoid System.
