Some thoughts on Cancer and the Bullmastiff
by Helene Hansmann

(featured in the Canadian Bullmastiff Journal Spring 2001)

Cancer, so often I have heard that so and so has died of cancer and it saddens me to hear of another Bullmastiff stricken with this devastating disease.  Bone cancer, skin cancer or lymphatic cancer often raises its ugly head, and it shortening your pets' life spans of our dogs.  Some say that it is line related or that it is in the Bullmastiff breed, while others claim that it is environmentally related.

Whatever the reasons, cancer is affecting the Bullmastiff and other dog breeds, but what is the actual cancer rate in which the Bullmastiff affected? Is it higher in the Bullmastiff as opposed to other breeds? I am still searching for a good up to date study of cancer in dogs for our readers which can be related to the Bullmastiff.  Puppy buyers who are selecting the kennel from to purchase their puppy often ask the difficult question - has your dogs  been affected by cancer? If you are relatively a new kennel with young animals, the answer could be - "NO". But, as years go by the honest answer will change, cancer does occur more often in older animals (6 years of age and older). How can the breeder decrease the incidence of cancer in their breeding stock when the prime breeding age is between 2-5 years?  What is an acceptable cancer rate for the Bullmastiff?

In Ontario, the lifetime risk of cancer in the human population is abut 31% for men and 25 % for women, according to a report in the American Journal of Public Health.  Dr. Stephen Walter of McMaster University Health Sciences Center in Hamilton and Colleagues calculated the rates for stomach, lung, uterus and prostate cancers in 49 counties of Ontario from 1976 to 1988.  Some interesting comments in the study were that in Northern Ontario higher rates of stomach cancer were present, while some areas near Lake Ontario and in Central Ontario had low rates.  Cancer is out there in the human population as well as in animals.  I do not have a risk percentage for animals referring to pets such as dogs and cats.

The most important know risk factors for gastrointestinal cancers are dietary, probably related to a low intake of fresh fruits and vegetables and high intake of nitrates which is used as food preservatives found in foods such as bacon.  Other risk factors include second hand smoke inhalation, over use of vaccinations, etc.

What are the symptoms of cancer? These are some of the many signs of cancer in dogs that can be observed:

1. Significant weight loss
2. Anorexia, lack of appetite
3. Swollen and tender glands
4. Dry cough that does not disappear
5. Tumors located throughout the body
6. Swollen and or tender parts of the body
7. Sudden lameness and chronic lameness
8. Anemic, decreased red blood levels in the body
9. Swelling of the abdominal cavity
10. Strange behavior

My best advise in extending the life expectancy of your bullmastiff is:

1. Never allow your dog to become obese.  Measure the amount of feed given daily.  Feed at least twice daily.

Try to feed your dog good NATURAL  BALANCED DIET with variety of foods, such as raw carrots, fruits, yogurt, boiled rice, barley or oats, boiled minced meat, ground flaxseed and kelp.  These enhance their diet. I strongly believe diet has a relationship to cancer rates.

Discuss with your vet the possible over use of vaccinations.  Routine vaccinations may be  extended to every 2-3 year rather than annually.

4. Keep your dog fit and well exercised.

5. Keep your dog stress free, remember dogs can be sensitive to family conflicts too.

6. Keep your home smoke free for your dog too.

If your dog has experienced cancer, let us know about it and share your thoughts on it .  Give us your advise and experience about cancer, as painful as it may be .  We may all learn from it.
