Pets
and secondhand smoke
by
Linda Lechler
She
sits by the window of her third story apartment hovered in
a small corner of the room smoking a cigarette and thinking
about Jack Daniels.
No,
Sarah Billings is not a closet smoker or alcoholic but a pet
owner who cares deeply for Jack, her 5-year-old hound-dog
mix. She has known Jack for his whole life and is concerned
about how her secondhand smoke may affect him.
"Dogs
age almost seven times faster than us," Billings said,
a junior majoring in psychology. "Secondhand smoke can
cause problems fast. I take Jack (to the vet) frequently and
he appears to be fine," Billings said. "But they
don't do any specific tests to see early signs (of secondhand
smoke)."
Billings
said she has smoked cigarettes around Jack for half of a year
and worries about his sporadic wheezing, coughing and hyperventilating
around cigarette smoke.
"I
am close with my dog," Billings said. "I would never
forgive myself if I caused his early demise."
Billings,
along with other pet owners, is slowly becoming aware of the
effects of secondhand smoke on pets. Two studies were done
at CSU's Veterinary Teaching Hospital headed by John Reif,
professor of epidemiology, and the department chairman for
environmental and radiological health sciences, and associates
that helped to bring awareness of secondhand smoke to the
public.
In
1992, Reif conducted a study entitled, "Passive Smoking
and Canine Lung Cancer Risk." Reif also headed the second
study of similar interests, in 1998, titled "Cancer of
the Nasal Cavity and Paranasal Sinuses and Exposure to Environmental
Tobacco Smoke in Pet Dogs."
"These
studies are really the first to make us aware of secondhand
smoke on animals," Reif said. "They are the first
of their kind."
There
were several factors taken into consideration during the studies,
such as number of smokers in the home, number of packs of
cigarettes smoked in the home per day by the heaviest smoker,
the time the dog spent inside the home, and the age, sex,
body size and skull shape of the dog.
"All
these factors involved are important," Reif said. "All
exposures are contributing factors."
According
to the study, a dog that has exposure to a smoker in the home
is 1.6 times more likely to develop lung cancer than a dog
that is not exposed to a smoker.The
study found that skull shape had an effect on the estimated
risk of lung cancer in dogs. Dogs with long noses (like German
shepherds) have a higher risk for nasal cancer and dogs with
short noses (like pugs) have a higher risk for lung cancer,
Reif said. This is because, in theory, a dog with a long nose
has an extra filtering system in its nose, so it is more likely
to develop nasal cancers, Reif said.
"Both
studies are important because they show exposure to secondhand
smoke has an increased risk for cancer of respiratory system
in dogs," Reif said.
He
said some of the warning signs of lung cancer in dogs include
chronic coughing, weight loss and abnormal fatigue. Warning
signs of nasal cancer include swelling over the nose or sinus
area, sneezing and bloody nasal discharge, Reif said.The
only real prevention for these cancers is to not smoke around
your pets, Reif said.
"Obviously
people are encouraged not to smoke," he said. "People
who choose to smoke should do so away from pets, outdoors."
Although
the public is slowly becoming aware of the effects of secondhand
smoke through studies like these, the concept is still unknown
to many. Out of 20 random practicing veterinarians called
in the Fort Collins and Loveland yellow pages, not one of
them knew a lot about any studies done about the effects of
secondhand smoke and pets. Also, none of these veterinarians
are currently talking to their clients about secondhand smoke's
potential negative effects.
This
lack of awareness may not be so prevalent at the CSU campus
this coming spring,however. The new approach to the subject
of secondhand smoke affecting pets was an inspiration for
a new campaign in the tobacco cessation program headed by
Jerusha Hall with the assistance of Andrea Boone at the CSU
Hartshorn Health Center.
"The
whole campaign started because as a smoker I was looking for
a different approach to tobacco education," Hall said,
a senior animal science major.
She
said the approach to tobacco cessation has been seen in the
same light for too long and finding a new twist might help
to reach more people. Hall said she takes better care of her
dogs then she does herself in some ways and knows she is not
alone in this behavior.
"To
me it was an approach that I hadn't seen before and maybe
it is something that would connect for some other smokers,"
Hall said. " The process of cessation is so difficult
and maybe just looking at things differently may help."
The
major goal of the pets and health campaign, which starts later
this spring, is for people on campus to gain some awareness
on the tobacco issue, Hall said.
This
project will include a poster campaign with resource numbers,
Web sites and a tentatively scheduled dog day on campus which
will include health checks for dogs, Frisbee and bandana giveaways,
getting your dog's photo taken with Mr. Butts (a speaker on
secondhand smoke and your pet) and a raffle for t-shirts.
This
event is tentatively planned for April 23, with the posters
coming out a week or two before the event.
