The Nova Scotia Duck-Tolling Retriever; otherwise know as the "Little River Duck Dog", looks somewhat like a small Golden Retriever. It is a well-muscled dog that is medium to heavy boned. It has a deep chest that is well-insulated for swimming in cold water. The coat is dense, and comes in various shades of red and orange. It usually has small white markings on the feet, chest, tail tip and sometimes face and may have a slight wave on its back, but the coat is otherwise straight. The ears are triangular and set high and are well back from the skull. The head is clean-cut and slightly wedge-shaped. The powerful, compact, well-muscled body is on sturdy, solid legs.

Sensible and very devoted to its family. An owner in Michigan credits her well-being to her dog, after he twice saved her, once legitimately and more than once "illegitimately." The first instance occurred in a hiking expedition where she ended up on an unstable ledge. This medium-sized dog braced himself so that his owner could grasp his collar and pull herself to safety. The other instance involved her swimming attempts. He would not let her go deeper than ankle-high water in order to keep her safe! These dogs are intelligent, easy to obedience train and good with children. They make great companion dogs as long as they get enough exercise to fulfill their energetic needs. Tollers may be a bit more reserved around strangers than the Golden Retriever. The same charming way this water dog has with his game, he demonstrates with his owner. He is hard-working and clever, and enjoys being with his master. His expression may seem low-spirited, but once in the hunt he is the happy hunter. The Toller's strong retrieving desire and playfulness are natural traits, both necessary for his tolling ability. Tolling (luring) is a natural trait (like pointing) and cannot be taught. They have an intense natural excitement about their duty. Young dogs need to practice; training sessions involve establishing a close relationship and having children throw things for them to retrieve. Some owners say the Toller is a retrieving fool. If one makes the mistake of throwing a ball for them, they will keep the unfortunate soul throwing until his arms gives out. These are excellent family pets which get on well with other dogs and animals. They are very patient with children.

The Nova Scotia Duck-Tolling Retriever originates from Canada. Tolling Red Decoy Dogs probably accompanied their masters from Great Britain to Nova Scotia. They were crossed with retrievers and working spaniels. It was developed to toll (lure) ducks in the manner of the fox. The clever manner in which foxes work together to obtain a duck dinner has been observed over the centuries. The Nova Scotia Duck-Tolling Retriever is the creation of skillful Canadian hunters. The Toller's rather unusual job is to lure ducks and geese within shotgun range, and to retrieve them from the water after they have been hit. From his concealed blind near the shore, the hunter tosses a stick parallel to the shore, and with great liveliness, but without barking, the Toller retrievers it. It may take a dozen or more throws before the ducks or geese become curious and approach the shore. When the overly inquisitive ducks are within shooting range, the hunter calls his dog back to the blind, stands up to put the birds to flight, and shoots. The Toller then acts as an efficient retriever. Indians utilized this mesmerizing practice by stringing a fox skin across a length of shore and yanking it quickly back and forth, simulating the movement of the fox. The breed used to be called the Little River Duck Dog or Yarmouth Toller, but when the Canadian Kennel Club began registering them in the late 1950's, the present name was established. FCI gave them full international recognition in 1982. There are a fair number of Tollers and breed specialty clubs in the USA.
