Weight loss
Weight loss is a common sign of cancer in dogs, and it can be caused by a variety of factors. One of the most common causes of weight loss in dogs with cancer is the increased metabolic rate associated with the disease. Cancer cells require a lot of energy to grow and divide, and this can lead to an increased demand for calories. As a result, dogs with cancer may eat more but still lose weight, or they may eat less but still lose weight because their bodies are not able to absorb nutrients efficiently.
In addition to increased metabolic rate, other factors that can contribute to weight loss in dogs with cancer include:
- Loss of appetite
- Nausea and vomiting
- Diarrhea
- Malabsorption
Weight loss can be a serious problem for dogs with cancer, as it can lead to muscle wasting, weakness, and a decreased quality of life. If your dog is losing weight, it is important to see your veterinarian to rule out any underlying medical conditions, including cancer.
Loss of appetite
Loss of appetite is a common sign of cancer in dogs, and it can be caused by a variety of factors. One of the most common causes of loss of appetite in dogs with cancer is the increased metabolic rate associated with the disease. Cancer cells require a lot of energy to grow and divide, and this can lead to an increased demand for calories. As a result, dogs with cancer may eat more but still lose weight, or they may eat less but still lose weight because their bodies are not able to absorb nutrients efficiently.
In addition to increased metabolic rate, other factors that can contribute to loss of appetite in dogs with cancer include:
- Nausea and vomiting
- Diarrhea
- Malabsorption
- Pain
- Depression
Loss of appetite can be a serious problem for dogs with cancer, as it can lead to muscle wasting, weakness, and a decreased quality of life. If your dog is losing weight or has a decreased appetite, it is important to see your veterinarian to rule out any underlying medical conditions, including cancer.
Lethargy
Lethargy, a state of extreme tiredness or lack of energy, can be a common sign of cancer in dogs. Dogs with cancer may experience lethargy due to a variety of factors, including the increased metabolic rate associated with the disease, pain, depression, and decreased appetite. The cancer cells require a lot of energy to grow and divide, which can lead to an increased demand for calories, resulting in fatigue and lethargy in dogs.
In addition, cancer can cause pain and discomfort, which can lead to decreased activity and lethargy. The pain may be caused by the tumor itself or by the pressure it puts on surrounding tissues and nerves. Depression is another common symptom of cancer in dogs, and it can also lead to lethargy. Dogs with cancer may feel depressed due to the physical discomfort they are experiencing, or they may be depressed due to the changes in their routine and environment.
Lethargy is a critical component of signs of cancer in dogs because it can indicate that the disease is progressing. If your dog is experiencing lethargy, it is important to see your veterinarian to rule out any underlying medical conditions, including cancer. Early detection and treatment of cancer in dogs can improve the chances of a successful outcome.
Difficulty breathing
Difficulty breathing can be a concerning sign of cancer in dogs, as it may indicate that the cancer has spread to the lungs or other parts of the respiratory system. There are several potential causes of difficulty breathing in dogs with cancer, including:
-
Tumors in the lungs or airways
Cancerous tumors can obstruct the airways, making it difficult for dogs to breathe. This can lead to coughing, wheezing, and shortness of breath.

Fluid in the chest cavity
Cancer can cause fluid to build up in the chest cavity, which can put pressure on the lungs and make it difficult to breathe. This is known as pleural effusion.
-
Metastasis to the lymph nodes
Cancer can spread to the lymph nodes in the chest, which can enlarge and put pressure on the airways or blood vessels. This can lead to difficulty breathing and other symptoms.
-
Pain
Cancerous tumors can be painful, and this pain can make it difficult for dogs to breathe deeply. Pain can also lead to anxiety and stress, which can further worsen difficulty breathing.
Difficulty breathing can be a serious problem for dogs with cancer, and it is important to seek veterinary attention promptly if your dog is experiencing this symptom. Treatment for difficulty breathing in dogs with cancer will depend on the underlying cause and may include medications, surgery, or radiation therapy.
Unexplained bleeding or discharge
Unexplained bleeding or discharge from any orifice in a dog's body can be a sign of cancer, especially if it is persistent or recurring.
-
Bleeding from the nose or mouth
Bleeding from the nose or mouth can be a sign of oral cancer, nasal cancer, or other types of cancer that affect the respiratory system.
-
Bloody or discolored urine
Bloody or discolored urine can be a sign of bladder cancer, kidney cancer, or other types of cancer that affect the urinary system.
