The Golden Retriever is a popular dog breed, originally developed to retrieve fowl shot during hunting. It is one of the most common family dogs because it is easy to handle, very tolerant, and is normally very happy and friendly. It is a low-maintenance dog and thrives on attention, regular exercise, a balanced diet, and regular veterinary check-ups. Golden Retrievers are usually compatible with all people and with other dogs. They typically bark when startled, but generally their friendly nature makes them poor security watchdogs. Golden Retrievers are particularly valued for their high level of sociability towards people and their willingness to learn. Because of this, they are commonly used as Guide dogs and as Search and Rescue dogs.
