Mars Veterinary kindly sent the following response to questions re their "Wisdom Panel" and it's ability to identify the American Pit Bull Terrier using DNA Profiling:

"Thank you for contacting Mars Veterinary.

The term “Pitbull” does not refer to a single or recognized breed of dog, but rather to a genetically diverse group of breeds.  Pit bull type dogs have historically been bred by combining guarding type breeds with terriers for certain desired characteristics – and as such they may retain many genetic similarities to the likely progenitor breeds and other closely related breeds.  If a pit bull type dog were tested, we might anticipate that the Wisdom Panel test might detect and report moderate to trace amounts of one or more distantly related breeds to those used to breed the dog, it is possible that one or more of the following breeds might be detected at moderate to trace amounts: the American Staffordshire terrier, Boston terrier, Bull terrier, Staffordshire Bull terrier, Mastiff, Bullmastiff Boxer, Bulldog and various small terriers like the Parson Russell.  These breeds would be detected because some markers in these breeds have genetic identity at a minority of the markers the Wisdom Panel test uses to the breeds in our database.

Mars Veterinary’s analysis of the many Pitbull type breeds, which are known to be closely related, indicates that this diverse group of dogs could be one or a mixture of American Staffordshire Terrier, Staffordshire Bull terrier, Boston Terrier and some Bulldog.  Due to the genetic diversity of this group, we cannot build a DNA profile for the Pitbull.  Any Pitbull type breed tested using Wisdom Panel™ MX Mixed Breed Analysis is likely to reveal a combination of several breeds.  For example, a Pitbull type breed might show up as 25% Boston Terrier, 25% American Staffordshire Terrier and 50% unknown.

Some local communities in the United States have put restrictions on pitbull ownership. Mars Veterinary™ encourages pet owners and care providers to be fully aware of their local laws, which vary across the country.

We hope this answers your inquiry.  If you have any additional questions, please do not hesitate to contact us at customercare@marsveterinary.com or
