Black dog syndrome or big black dog syndrome is a phenomenon in which black dogs are passed over for adoption in favor of lighter-colored animals.[1] Black cats are similarly reported to be subject to the same phenomenon.[1]
While earlier studies did find some evidence for a lower adoption rate for black dogs, other studies have found that they are actually adopted more quickly than dogs with lighter coat colors. This has led some experts to dismiss black dog syndrome as a 'myth'.[2][3]
