The Majority of Pitbull-Type Dogs Are Mixed Breed Dogs
In yet another blow to BSL, the most recent peer-reviewed study on the DNA of shelter dogs concluded that one of the main components of BSL, identifying a dog's breed based on appearance, is highly unreliable with accuracy ranging between a low of 10% and a high of 67%. Published last month, the largest study on the DNA of shelter dogs to-date also concluded that 98% of pitbull-type dogs are mixed breed dogs and that behavior is more important than heritage (DNA/breed) when considering dogs for adoption. Furthermore, the study found that dogs labeled as a pitbull-type breed had an average DNA concentration of 43.5% from pitbull-type ancestry which would challenge the majority of breed-based bans that target dogs with a genetic background of "50% or more" from pitbull-type breeds. Below, we highlight key conclusions and information from the latest scientific study to contradict BSL and breed-based bans.
