The Flat-coated Retriever is a gundog breed originating from England. It was developed as a retriever both on land and in the water. The Flat-Coated Retriever breed standard calls for males to be 23–25 in (58–64 cm) tall at the withers, with a recommended weight of 60–80 lb (27–36 kg), and for females to be 22–24 in (56–61 cm), with a recommended weight of 55–75 lb (25–34 kg). The Flat-Coated Retriever has strong muscular jaws and a relatively long muzzle. Its head is unique to the breed and is described as being 'of one piece' with a minimal stop and a backskull of about the same length as the muzzle. It has almond-shaped, dark brown eyes with an intelligent, friendly expression. The ears are pendant, relatively small, and lie close to the head. The occiput (the bone at the back of the skull) is not to be accentuated (as it is in setters, for example) with the head flowing smoothly into a well-arched neck. The topline is strong and straight with a well-feathered tail of moderate length held straight off the back. This breed should be well-angulated front and rear, allowing for open, effortless movement. (Source: Wikipedia.org, CC BY-SA)
