Here are two different types of retrievers from the Sporting group of dog breeds: Chesapeake Bay Retriever and Curly-Coated Retriever.
Chesapeake Bay Retriever
Here is one of America's native stocks, bred along the shores of Maryland to recover ducks from the rough, icy waters of Chesapeake Bay. His 1 1/2-inch coat is crisp and oily to protect him when swimming. His short body is higher at the hindquarters than at the shoulders, his legs are aligned, and his hare feet are webbed. His head is wide with a relatively short muzzle. His tail is straight or slightly curved and eyes are medium-large,yellow or amber.
WEIGHT: males 65-80 pounds; females 55-70 pounds
HEIGHT: males 23-26 inches; females 21-24 inches
COLOR: any color from dark brown to faded tan or dead grass.
Came down from the 16th century English WaterSpaniel, the Curly-Coated Retriever is considered to be one of the oldest members of the Retriever family. His tight curls cast off water and also protect his skin from thick brush. His body is quite short, his chest deep, feet round and pack together, and the tapered tail set straight out. His head is long having jaws that are a bit lean, eyes huge but not prominent, and curl-covered ears resting close to the head. Actually, as his name indicates, he is a mass of curls downright to the tip of his tail.
WEIGHT: 60-70 pounds
HEIGHT: 23-24 inches
COLOR: black or liver.
