What advantages are there to DNA testing dogs?

DNA Fingerprinting
A DNA fingerprint is literally your pet’s genetic serial number.
Having a record of your dog ‘s DNA fingerprint can prove beyond a shadow of a doubt that your pet is “your pet”. Even if your pet is a mutt, DNA testing can tell you many of the breeds in it’s ancestry.
DNA testing can screen for dozens of inherent, genetic diseases.
INCLUDING:
Progressive Retinal Atrophy (PRA)
Hypothyroidism with Goiter (HTG)
(Congenital Hypothyroidism)
Cystinuria (CYST)
Globoid Cell Leucodystrophy (GCL)
Neuronal Ceroid Lipofuscinosis (NCL)
Phosphofructosokinase Deficiency (PFK)
Von Willebrand Disease (vWD)
Narcolepsy (NARC)
Cone degeneration (CD)
Canine Leucocyte Adhesion Deficiency (CLAD)
Hemophilia B (HmB)
Muscular Dystrophy (MD)
Myotonia Congenita (MC)
GMI Gangliosidosis (GMIG)
Retinal Dystrophy (prad)
SCID (DNA-PKc & DNA PKc2)
Mucopolysaccharidosis Type VII (GUSB_NOSVVIII)
Thrombasthenic Thrombopathia (THROM)
Most dogs will test negative. This means they don’t carry the gene that causes a particular disease. Obviously, this is good news. Its also good information, particularly if you are a breeder, to know absolutely that your pet will not get the disease in the future.
Unfortunately, some pets will test positive or as a carrier of a bad gene. A positive result means your dog definitely has or will develop the disease in the future.
A carrier means that your pet does not have the bad gene(s) but could pass them to future offspring if bred with an animal also being a carrier of the particular disease.
As a breeder these are things I need to be aware of to be able to offer healthy pups.
DNA Color Traits
DNA tests can also show me for certain which color traits each of my dogs carry. With this information, I am able to take the guesswork out of producing litters with a good range of color. Some prefer white dogs, some chocolate, or apricot, etc. With this information I can better predict whether my black dams will produce anything other than an all black litter and whether my male is a good genetic match for my females.
