Improper coat


Brown curly improper coat


Black wavy improper coat

A heritable hair coat issue in Portuguese Water Dogs is “improper coat”.
Portuguese Water Dogs with improper coat do not have the coat described in the breed standard.
A wavy “improperly coated” PWD will tend to look like a Flat Coated Retriever or Border Collie. A curly “improperly coated” PWD will tend to look like an American Water Spaniel or Curly Coated Retriever.
It is also possible for “improperly coated” dogs to have some undercoat and possibly shed. This condition is one of appearance. In several other breeds which present with “improper coats” for their breed, the mode of inheritance for the improper coat is a simple recessive. It is likely that it is also a simple recessive in Portuguese Water Dogs although this has not yet been confirmed.
