"Black Dog Syndrome: FACT OR FICTION". Lowcountry Dog. 2 October 2017. "Christy L. Hoffman, a PhD and Professor of Animal Behavior at Canisius College conducted a study in 2016 trying to figure out if BDS is really a factor in adoptions. She investigated the role of color, age, sex, and breed on the outcomes of the adoption of dogs in two animal shelters in the United States over four years of adoption records (nearly 16,700 dogs). This study proved black dog syndrome is a myth, and the data actually showed that black dogs had a shorter time span spent in the shelter than dogs of other colors."

Binkley, Collin. "'Black dog' theory tested". www.spokesman.com. Associated Press. "There's no firm science to support the existence of Black Dog Syndrome, and some studies have dismissed it as a myth. Maryann Regan, director of shelter operations at the Animal Rescue League of Boston, said she doesn't see widespread bias against black dogs."
