The Nova Scotia Duck Tolling Retriever is a medium-sized gundog bred primarily for hunting. It is often referred to as a 'toller'. It is the smallest of the retrievers, and is often mistaken for a small Golden Retriever. Tollers are known to be intelligent, easy to please, alert, and high-energy dogs. The name 'toller' is derived from their ability to lure waterfowl within gunshot range. The breed originated in Yarmouth County, Nova Scotia, Canada. The American Kennel Club ranks the toller as the 87th most popular dog breed. Tollers are generally hardy. However, like almost all dog breeds, certain genetic disorders are known to occur in the breed. This is sometimes blamed on a relatively small gene pool. The Finnish breed club states the largest health problems in the breed tend to be immunity related. They can be affected by eye problems and hip dysplasia and are predisposed to immune-mediated rheumatic disease and steroid-responsive meningitis–arthritis. Tollers are well adapted for water, having a double coat and webbed paws.
