EDTA Blood Samples Needed For Dal-Negative Blood Type Study

Breed(s): Doberman Pinscher, Dalmatian
Study Type: Blood Sample
Study Location: Université de Montréal & University of Pennsylvania

Recently, an extremely rare blood type, named Dal-negative, was discovered following the investigation of an anemic Dalmatian requiring a blood transfusion. This discovery was possible because of the mobilization of Dalmatian owners.

A similar scenario happened not long ago, but this time, it involved two anemic Doberman pinschers. Following a preliminary study, we estimate that a third of Doberman Pinschers and a quarter of Dalmatians have this rare Dal-negative blood type. In other words, one Doberman Pinscher out of three and one Dalmatian out of four is Dal-negative, and could have a very difficult time finding compatible blood products if needed, as 100% of non-Dalmatian and non-Doberman tested are Dal-positive.

The purpose of this study is to establish the frequency of the Dal-negative blood type and its mode of inheritance in Doberman Pinschers and in Dalmatians.

Typing only requires 2 ml fresh EDTA blood sent by express courier with an ice pack.  The PennGen Lab and the Blood Bank of the Université de Montréal are offering free Dal blood typing for Dalmatians and Doberman pinschers. Submission can be made via PennGen website for USA samples.  We are also asking for completion of a brief questionnaire when submitting sample.
