Voith and Irizarry are also prominent members of the National Canine Research Council, a front for the pit bull advocacy organization Animal Farm Foundation, and of several other pro-pit bull lobbying and promotional entities. The above statement from Significant neuroanatomical variation among domestic dog breeds lead author Erin Hecht is taken from an interview with Harvard University staff writer Jill Radsken, published on September 3, 2019, and in accurate context pertains to the distinction between innate instinctive behavior, such as reactive fight-or-flight, and trained behavior that builds upon instinct.

While the study wasnt designed to directly link brain shape to behavior, Sanders said, the results offer some hints. This question was answered in detail by Genetic mapping of canine fear and aggression, by Isain Zapata, James A. Serpell, and Carlos E. Alvarez, published on August 8, 2016 by BioMed Central.
