Retriever is a gun-dog type rather than a single breed. It covers dogs developed to find shot birds and carry them back gently, and on adoption listings it most often means a Labrador or Golden Retriever mix, or a dog with that look and unknown ancestry. Most weigh 50 to 80 pounds and have a dense, water-resistant coat that sheds year-round.
Retriever-type dogs are usually sociable, food-motivated and eager to work with people, and a long, bouncy adolescence is common. In Springfield, that energy pairs well with the city's greenways and four distinct seasons, though the coat needs regular brushing to keep up with spring mud and summer humidity. Because ancestry varies, meeting the dog and watching how it behaves tells you more than the label does.
