Competing Interests

Helle Friis Proschowsky has a potential conflict of interest in that she works for the Danish Kennel Club, which has clear vested interest in breeding of purebred dogs. However, Helle Friis Proschowsky has had no final say in any matters that could relate to this potential conflict of interest. Also, this potential conflict of interest does not alter our adherence to PLOS ONE policies on sharing data and materials.
