Labrador Retrievers are medium to large-sized dogs known for their distinctive and recognizable appearance. Here are some key physical characteristics of Labrador Retrievers:

1. Size: Labradors are considered a medium to large breed. Adult males typically stand around 22.5 to 24.5 inches (57 to 62 cm) tall at the shoulder, while females are slightly smaller, ranging from 21.5 to 23.5 inches (54 to 60 cm) in height.
2. Weight: Adult Labradors typically weigh between 55 to 80 pounds (25 to 36 kg). However, some may be even larger or smaller depending on factors like genetics and diet.
3. Body: Labradors have a strong, athletic build with a deep chest and a broad back. They have a well-balanced, muscular body that is both agile and powerful.
4. Coat: Labradors have a short, dense, and water-resistant double coat. Their outer coat is straight and coarse, while the undercoat is soft and insulating. This coat helps them stay warm in cold water and provides protection from the elements.
5. Coat Colors: Labradors come in three primary coat colors:
   • Yellow: Yellow Labradors can range from pale cream to a deep fox-red color.
   • Black: Black Labradors have solid black coats, and their noses are also black.
   • Chocolate: Chocolate Labradors have brown coats, and their noses are brown as well.
6. Head: Labradors have a distinctive head with a broad skull and a well-defined stop (the point where the forehead and muzzle meet). Their muzzle is fairly wide and tapers to a black or brown nose, depending on coat color.
7. Eyes: Labrador Retrievers have expressive, round eyes that are usually brown or hazel in color. Their eyes convey a friendly and intelligent expression.
8. Ears: Labradors have medium-sized, pendant (hanging) ears that are set fairly close to the head and hang down close to the cheeks.
9. Tail: They have a strong, thick tail that is often referred to as an “otter tail.” The tail is usually thick at the base and gradually tapers towards the tip.
10. Feet: Labradors have compact, webbed feet, which make them excellent swimmers. The webbing between their toes helps them paddle efficiently in the water.
11. Gait: Labradors have a smooth, free-moving gait that reflects their athleticism. They move with grace and purpose.
