Abstract
The
entire canine genome is scheduled to be sequenced by researchers at the
Whitehead Institute/MIH Center for Genome Research by the end of 2004.
Thus, new genetic technologies are likely to be developed that can soon
predict certain aspects of health and temperament in dogs. The C. familiaris
is similar in size to that of humans and other mammals, with an
estimated 2.8 billion base pairs. Although, the boxer was chosen as the
first breed to sequence, it will have application for all dog breeds.
Once the entire genome is sequenced, genetic markers for specific
diseases and temperaments may be developed, which can guide breeders to
make informed decisions concerning breeding management. Such a
technology may be useful for guide and service dog organizations that
have breeding colonies. It is important that the human-animal bond be
preserved for as long as possible, both for pet owners and also for
those disabled individuals who depend upon a dog for independence and
mobility. Because genetic diseases may not manifest in carriers, and
some genetic diseases do not manifest until after a dog is older and has
already produced other animals with the same defect, genetic markers to
identify some of the over 400 genetic diseases could be very useful in
promoting canine health.
