Retriever isn't one breed. It's a type of gun dog, and on adoption listings the label usually points to a Labrador or Golden Retriever mix, or a dog with that look and unknown ancestry. Chesapeake Bay, Flat-Coated, Curly-Coated and Nova Scotia Duck Tolling Retrievers belong to the same family. Developed to find shot birds and bring them back gently, these dogs are sociable and eager to work with people.
Most retriever-type dogs are medium to large, usually 50 to 80 pounds, with a water-resistant double coat that sheds moderately to heavily. Expect a long, bouncy adolescence, a love of food and a habit of carrying things around in their mouths. In Gainesville, that means planning for daily exercise, regular brushing and some muddy paws in a place where it rains all year. Since ancestry varies, a dog's age and behavior say more than the label.
