Golden Retrievers were developed in 19th-century Scotland as gun dogs that retrieved birds gently from land and water. That heritage shows in the dense, water-repellent double coat, feathered legs and soft expression, and in a retrieving instinct that has many Goldens carrying toys to the people they love.
Many Goldens are friendly, patient and eager to please, though every dog is an individual and a rescue Golden's history matters as much as its breed. They mature slowly, often staying exuberant and mouthy for two or three years, and they shed heavily. In LA, expect to pair daily exercise with cooler-hour outings and regular brushing, and consider an adult or senior if you want a calmer start.
