Dog DNA Testing Generates Debate

More dog owners are having their pets’ DNA tested, but some experts are warning against it.  

Several companies now test dogs’ DNA so pet owners can get info on their health and heritage.

But the test have stirred debate about standards, interpretation and limitations.

For example:  one couple put their dog down because they interpreted DNA results to mean she had a rare, degenerative neurological disorder, when in fact her ailment might have been something more treatable.
