SCHAUMBURG, Ill., July 2 IDC-9-11-Dogs-Study
SCHAUMBURG, Ill., July 2 /PRNewswire/ -- A new study in the Journal of the
American Veterinary Medical Association reveals that New York Police
Department dogs deployed to the World Trade Center after the terrorist attacks
of September 11, 2001, have not experienced any long-term health effects.
The study focuses on 27 dogs that assisted in relief efforts at the site,
many of which remained deployed throughout the 37-week cleanup operation.
Both short-term and long-term health assessments were conducted.
According to the study, about 63 percent of the dogs had some type of
health disorder during the first week, including fatigue, eye irritation,
respiratory tract problems, decreased appetite, dehydration and cuts. What
surprised the study's authors, however, was that only mild and infrequent
health conditions were identified during a five-year follow-up period. None of
the dogs, according to the study, was identified as having chronic respiratory
tract disease or any type of blood disorder.
Nineteen of the 27 dogs were still alive and apparently healthy five years
later. In fact, the five-year mortality rate for the 27 working dogs examined
in the study was similar to the rate for a control group of household pets and
law enforcement dogs that had not been dispatched to the site.
"The general good health of the dogs studied was an unexpected result,"
said Philip Fox, DVM, the study's lead author and director of The Caspary
Research Institute of The Animal Medical Center in New York City. "The dogs
appeared to be unaffected in the long term by their exposure to the smoke,
dust and toxins they encountered while working at the World Trade Center
site."
The findings are in contrast to some human emergency responders who worked
at the site, as various studies have identified increases in the rates of
illness and the severity of various symptoms of respiratory tract disease.
The reason that the dogs appeared to suffer so few long-term health
conditions may be due to differences between human and animal airways and
differences in lung defense mechanisms.
