Retriever isn't one breed. It's a gun-dog type, and on adoption pages in Richmond it usually means 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, so the dog you meet may not match any single description.
Most are large, sturdy and food-motivated, roughly 50 to 80 pounds, with a water-resistant double coat that sheds. They like people and like to carry things, which suits fetch on the river trails but means muddy paws after rain, when spots like Huguenot Flatwater turn soggy. Adolescence can be long and bouncy, so budget for training classes and patience.
