West Lafayette, Ind. -- We know that women tend to live longer than
men, but a new study shows that the same may be true in dogs,
especially if a female dog's ovaries are not surgically removed
early in life.
A study conducted at the Gerald P. Murphy Cancer Foundation compared
the medical histories, ages and causes of death in 119 long-lived
rottweilers with a longevity of at least 13 years with 186
rottweilers with a normal longevity of about 9 years. The study
was published in the December issue of the journal Aging Cell.
"Like women, female dogs in our study had a distinct survival
advantage over males," said the lead researcher David J. Waters,
associate director of Purdue University's Center on Aging and the
Life Course and a professor in the Department of Clinical Sciences.
"But taking away ovaries during the first four years of life
completely erased the female survival advantage. We found that
female rottweilers that kept their ovaries for at least six years
were four times more likely to reach exceptional longevity compared
to females who had the shortest lifetime ovary exposure."
This study's findings are in line with those of a study conducted
earlier this year at the John Wayne Cancer Institute in Santa Monica,
Calif., of 29,000 who had hysterectomies because of benign uterine
disease. Although those women whose ovaries were removed before
50 years of age were protected against ovarian, uterine and breast
cancer, increased mortality from other causes was noted compared
with those who had their ovaries for at least 50 years.
Both studies call into question the automatic removal of the ovaries
when hysterectomies are performed in dogs and women.

P.S. So do you NOT spay your dog?
Well good question. I have always said what I was
taught that the benefit of spaying is to PREVENT
things like Mammary Cancer.
Now I would wonder about spaying ( and neutering) the larger breeds
later in life- such as after 2 years of age. Clearly we are in a
learning phase- Talk to your own Veterinarian, and point him or her
to the article.
P.P.S. Knowing that there are MANY things your pet has to deal with,
I do advise giving some type of supplement allowing them to BETTER
fight and PREVENT disease.
Ensure that you have ingredients for Arthritis, Allergies,
Vomiting/Diarrhea, and Immune Supportive products ( ie Antioxidants
protecting against free radical damage)
One such supplement is here- and you can get it for 50% OFF with
3 Fr.ee bonuses now:
