Dog cancer symptoms: Could your dog have cancer?

A sick dog is surrounded by medication.
When a dog has cancer, he can exhibit one pet health symptom or numerous symptoms associated with the disease. Dogs can develop cancer at anytime in their lives, but they are most susceptible to the disease once they become middle-aged. Cancer is the leading cause of death in dogs over the age of ten.

The dog cancer symptoms that develop depend on the type of cancer the dog has. A common symptom of skin cancer is abnormal swellings or growths on the body that do no go away with time or that continue to get larger. A sign of dog lymphoma is swelling of the lymph nodes that are located throughout the body.

Weight loss is another common sign of cancer in dogs. The dog may or may not have a loss of appetite associated with the weight loss. Dogs may experience difficulty eating or swallowing. This is common in dogs that have oral cancer or enlarged lymph nodes in the neck from lymphoma.

Dogs with cancer may exhibit lethargy or a loss of energy. A dog with bone cancer may experience lameness or increased stiffness in the limbs. Difficulty breathing, urinating and defecating may occur with any type of cancer.

Dog health care needs to be monitored when they display symptoms of cancer, as their health can deteriorate quickly. It’s important to take your dog to the veterinarian as soon as he begins exhibiting any symptoms of the disease. Having dog health insurance will allow you to get your dog diagnosed and treated quickly. Due to the nature of cancer, a delay in getting your pet checked out could be the difference between life and death.

    My dog is around 9 years old and she my family believes that she has cancer but we are not completely sure. It looks like she has moles on the interside of her thighs and there are bumbs on them too it doesnt seem to be getting worse or better, it is red sometimes. She licks it consantly. We have another dog that is around 1 and she is very hyper and our 9 year old dog was shaking and than she attacked our other dog. My mom thinks that our 9 year old dog has either gone crazy or is in serious pain. Can you give me any advice?
