Canine Heritage Breed Test, the "Mutts-have" Dog DNA Test, Announces Summer Special

On-line Pricing Offered for Limited Time Only
CALVERTON, Md.--(Business Wire)--
The leader of the pack in dog DNA testing announced today that the Canine
Heritage Breed Test will be offered at a special rate beginning July 6, 2009.
Pet lovers curious about the breed mix of their dogs will be able to buy the
test, which normally sells for $119.95, for only $99.95.

The offer is only available on its website, www.canineheritage.com, the company
said.

"We recognize that the economy has forced people to make hard choices in their
everyday purchases and we didn`t want their mutts to get the short end of the
stick," noted MetaMorphix, Inc. CEO Dr. Ed Quattlebaum. "The reduced price, if
only for a short time, will be a welcome opportunity for people who want to
understand more about their pet`s temperament and breed composition."

The at-home DNA test helps resolve the canine conundrum by using sophisticated
DNA analysis to match the profile of a mixed breed dog to a database of over 100
recognizable AKC pedigree breeds to establish the breed mix of the dog. No need
to subject your dog to an invasive blood test. The test kit includes a time
proven, easy and painless cheek swab that customers rub along the inside of
their pet`s cheek to collect cells. The swab is mailed to the company`s lab for
DNA analysis, with results coming back to pet-parents in about 4 weeks in the
form of a frame-quality Certificate of DNA Breed Analysis.
