The Golden Retriever is a large, strongly built breed with a dense, water-repellant wavy coat.As a dog with origins in pedigree breeding, and due to its widespread historical popularity, some regional variations have emerged in the breed; therefore, the three subtypes of the Golden Retriever reflect the typical variations in dimensions and coat. However, all Golden Retrievers are blonde, yellow, or gold in colour and all subtypes are susceptible to the same health problems.Golden Retrievers also are very smart dogs that are loyal and friendly to their caregivers
