Hounds are hunting dogs. The Finnish Spitz is unusual in that it hunts birds and indicates their presence in a tree by standing next to the tree and barking. Hounds tend to concentrate on the chase and not necessarily returning when called. They also have loud barks which they like to use. Sporting, or Gundogs, help in finding and catching feathered and furry game.
Retrievers bring back game.
Spaniels do both. Most Sporting dogs tend to be trainable, gentle, and quiet dogs. Terriers are the rodent-catchers of the canine world. They are brave and very intelligent dogs. Terriers vary in size, from large Airedales, down to medium-sized Lakeland Terriers, to smaller dogs like the Norwich Terrier.
