Carrier
A dog that has only one copy of an abnormal gene for a recessive disease. Carriers are not typically expected to have any features of the disease but are at risk of passing on the disease to offspring if bred with another Carrier of the same condition.
Normal
Indicates that testing found no indicators that the dog is a carrier or affected by the disease/condition being tested for.
Affected
This dog has two mutated copies of the gene and is at risk for developing the disease.
Normal By Descent (NDB)
NDB means that either both the dam (mother) and sire (father) are both non-carriers or one parent and an ancestor of the other parent are both non-carriers. In the case of NBD, no actual test was performed.
