A few weeks ago
I posted about my mother's dog, Nanai, an apparent
Pit-
Shepherd mix with an odd of instinctive behaviors.
We wiped Nanai's cheek with a swab from
Canine Heritage and, a few weeks later, got the results: No primary breeds (meaning neither of her parents was a purebred), and as a secondary breed,
Staffordshire Bull Terrier.
(According to Canine Heritage, a secondary breed is one that's "easily recognizable within your
dog. While these breeds may have a strong influence on your pet, each
breed listed makes up less than the majority of your dog's DNA.")
Staffordshire Bull Terrier was not a big surprise -- we'd figured Nanai was a bully breed, and the Staffordshire Bull Terrier, while descended from the same line as the American Staffordshire Terrier, is smaller and, according to our
Dog Breed Guide, was originally used for killing rats (which would explain Nanai's high prey drive and mouse-killing abilities).
But some big surprises turned up "in the mix."
