A diagnosis of cancer is frightening for many pet owners, but with today's medical treatments and nutrition, there is hope.

What Is Cancer?

Cancer is a condition associated with the uncontrolled growth of abnormal cells within the body.  These cells may form masses (tumors) that can create a variety of painful and serious problems.

Causes of Cancer

Factors that can influence the likelihood of a dog developing cancer include:

• Age - Nearly half of all dogs over 10 years old will develop cancer.

• Breed - Certain tumors are more common in specific breeds, e.g., skin tumors in Boxers, spleen tumors in German Shepherds and bone cancer in giant breeds.

• Gender - Some cancers develop under the influence of sex hormones.

• Environment - Exposure to chemicals, such as some pesticides and herbicides, and radiation.

Signs of Cancer

Due to the complex nature of cancer, many different signs may indicate the presence of the disease.  The following are some of the most common signs:

• Abnormal swellings that persist or continue to grow
• Sores that do not heal
• Weight loss
• Changes in appetite
• Bleeding or discharge from any body orifice
• Offensive odor
• Difficulty eating, swallowing or breathing
• Loss of stamina
• Persistent lameness or stiffness
• Difficulty in urinating or defecating

Home Care

• Watch for additional signs of illness.  If they appear, contact your veterinarian.
• Feed only the food recommended by your veterinarian.
• Check carefully for any new lumps or bumps on a regular basis.
• Maintain your dog's usual routine whenever possible.
• Monitor your dog's weight, activity and general health.
• Dogs receiving chemotherapy may experience specific side effects.  Discuss these with your veterinarian.

Feeding Recommendations

Cancer patients undergoing chemotherapy or radiation have increased protein and energy demands.  Your veterinarian may recommend a food proven to increase survival time and improve the quality of life for dogs undergoing cancer treatment.
