Shih Tzus are prone to various types of cancer, with lymphoma being the most common.
According to statistics, 1 in 5 Shih Tzus will develop lymphoma in their lifetime.
Shih Tzus are also at risk for skin cancer, with basal cell carcinoma being the most common type.
Skin cancer can appear as a lump or sore on the skin that doesn't heal.
Regular grooming and skin checks can help identify skin cancer early on.
Early detection is key to successful treatment and recovery.
Symptoms and Signs
As a dog owner, it's essential to be aware of the potential symptoms of cancer in Shih Tzus, so you can catch any issues early on.
Lumps and bumps under the skin are one of the most common signs of cancer in dogs, including Shih Tzus. These can be firm, raised, or even rubber-like in texture.
Abnormal odors from the mouth, ears, or other parts of the body can also indicate cancer. This can be a sign of oral cancer, which is a common type of cancer in dogs.

Abdominal swelling is another symptom to watch out for, as it can be a sign of various types of cancer, including skin cancer.
Here are some common symptoms of skin cancer in dogs:
- Firm, raised wart-like blemishes (squamous cell carcinomas)
- Rubber-like, inflamed sores (mast cell tumors)
- Strange-colored lumps or bumps on the lips, mouth, pads of feet, toenail beds (melanomas)
- Indications that your dog is in pain, such as a limp
Changes in appetite, weight loss, and lethargy or depression are also potential symptoms of cancer in dogs. These can be caused by a variety of factors, including pain, discomfort, or underlying health issues.
If you notice any of these symptoms in your Shih Tzu, it's crucial to consult with your veterinarian immediately. Early detection and treatment can significantly improve the chances of a successful outcome.
Causes and Prevention
Genetics play a significant role in a Shih Tzu's risk of getting skin cancer. Hormonal abnormalities and certain types of viruses can also contribute to this risk.
Sun exposure is a major trigger for skin cancer in dogs, and squamous cell carcinomas are a common type of skin cancer that can cause damage or destruction in surrounding tissue. These tumors are aggressive but don't usually spread to surrounding lymph nodes.
To prevent skin cancer, it's essential to get your Shih Tzu out of the sun when the UV index is 3 or greater. This is when skin damage is likely, and susceptible dogs should be kept in the shade or inside.
A normal hair coat protects the skin almost as well as a shirt, so be especially careful if you've shaved your dog for summer.
Most Common Causes
Genetics play a significant role in your dog's risk of getting skin cancer.
Hormonal abnormalities can also trigger skin cancer in dogs.
Exposure to certain types of viruses is another potential cause.
The amount of time your dog spends in the sun can increase their risk of skin cancer.
Chemicals in the environment can contribute to skin cancer in dogs.
Squamous cell carcinomas, a type of skin cancer, are often caused by sun exposure.
These tumors can be aggressive but don't typically spread to surrounding lymph nodes.
Damage or destruction can occur in the tissue surrounding the tumor.
Prevention
Prevention is key to avoiding skin cancer in dogs. Get your dog out of the sun whenever the UV index is at 3 or greater.
A normal hair coat protects the skin almost as well as a shirt. This is especially important if you've shaved your dog for summer.
Use sunscreen on your dog's exposed skin, like the pink nose area. However, be aware that using creams on pink skin can pick up dirt, so be prepared to bathe your dog frequently.
Remember to have your dog's small lesions checked before they become large ones.
Diagnosis and Treatment
Diagnosing cancer in your Shih Tzu requires a thorough examination by a veterinarian, including blood work, urinalysis, and imaging tests like X-rays or CT scans. Your vet may also perform a biopsy to determine the type of cancer.
A veterinarian can only accurately diagnose canine cancer, so it's essential to schedule regular wellness exams for your Shih Tzu. Treating cancer before it advances is key to successful recovery.
Your veterinarian will evaluate your Shih Tzu's overall health status, including age, general health, tumor type, biological behavior of the tumor, and the stage of cancer, to determine the best treatment options. Treatments for dogs with cancer can include surgery, radiation therapy, chemotherapy, and holistic or herbal therapy.
Here are some common treatment options for canine cancer, including:
- Chemotherapy
- Surgery
- Radiation therapy
- Holistic or herbal therapy
Combining treatment options can be effective, but it's essential to discuss the potential risks and benefits with your veterinarian.
Diagnosis
Your veterinarian will perform a thorough physical examination, which may require sedation to look inside your dog's mouth for tumors or other abnormalities.
Bloodwork and a urinalysis are essential to planning appropriate treatment, providing insight about your dog's overall health status.
X-ray images of your dog's chest may show whether a growth in the mouth has spread to the chest.
A CT scan or MRI of your dog's mouth may be recommended to determine how invasive the tumor is.

A tissue biopsy will be taken to determine which kind of cancer is present, and this can be done in various ways, including taking a sample from the tumor or removing the entire visible mass.
In some cases, a small sample from the lymph nodes may be taken to determine whether there are cancerous cells there.
Your veterinarian may refer you to a specialist, known as a veterinary oncologist, who focuses on cancer development and treatment.
Treatment Options
Treatment decisions for dogs with cancer depend on several factors, including the dog's age, overall health, tumor type, and the stage of the cancer.
Surgery is often the primary treatment option for dogs with cancer, but it's not always the best choice. The goal of surgery is to remove the tumor, but if the tumor has microscopic fingers that surgery can't remove, cancer will likely return.
Radiation therapy is used to damage the DNA of cancer cells, killing them. This treatment is most effective in tumors with rapidly dividing cells and can be used on its own or in combination with other treatments.
Chemotherapy uses drugs to kill or slow the growth of cancer cells. These drugs can be administered in pill form or given intravenously and are often developed from natural sources like plants or bacteria.
Combining treatment options can be effective, but it's essential to address potential interactions and unintended harm with your veterinarian.
Here are some common treatment options for dogs with cancer:
- Surgery
- Radiation therapy
- Chemotherapy
- Holistic or herbal therapy
The type of treatment recommended will vary based on the dog's diagnosis, and your veterinarian may suggest a combination of treatments.
Types of Cancer
Shih tzus, like all dogs, are prone to various types of skin and oral cancers. Malignant melanomas, which can grow rapidly and spread to other organs, are a common type of skin cancer in dogs, often found in the mouth or on mucous membranes.
Mast cell tumors, the most common skin tumors in dogs, develop in the immune system's mast cells and are influenced by genetics and hormones like progesterone and estrogen.
Some common symptoms of oral cancer in Shih tzus include excessive drooling, bad breath, difficulty chewing or drinking, and blood coming from the mouth.
Oral cancer symptoms can also include oral pain, weight loss, loose teeth, visible masses in the mouth, and swollen or deformed areas on the face.
Oral Health Issues
Shih Tzus, like all dogs, can develop oral health issues that may be a sign of cancer. Excessive drooling is a common symptom of oral cancer in dogs.
Bad breath, or halitosis, is another symptom that may indicate a problem. If your Shih Tzu is experiencing persistent bad breath, it's a good idea to have them checked by a vet.
Difficulty chewing or drinking can also be a sign of oral cancer. This can be due to a tumor or other growth in the mouth.
Blood coming from the mouth is a concerning symptom that requires immediate veterinary attention. If you notice blood in your Shih Tzu's mouth, don't hesitate to seek help.
Oral pain can also be a symptom of oral cancer. This can manifest as whining, panting, or avoiding food and water.
Weight loss is another symptom that may indicate oral cancer. If your Shih Tzu is losing weight despite eating normally, it's a good idea to have them checked by a vet.
