A sporting dog on four sides, the Chesapeake Bay Retriever stands out in many fields: the country or water, the beauty rink or obedience track, as well as at home.

A well done Retriever, without exaggerating, the Chesapeake is distinguished for its dry grass colored coat, in tonalities that go from dark brown to a matte hay color. It should have a wide and round skull, with a medium stop, small, very high inserted ears, and eyes medium large, with retracted sides and a short back, well combined, and with a deep and wide chest. The hindquarters are mostly potent, with the rump slightly higher than the shoulders, which are sloped and not limited to ease free movement. The feet have membranes and the carpus straight; the hind dewclaws are removed. The tail reaches the hock, and straight or slightly curved; without too much long hair. The coat’s quality and texture is very important: the external coat is thick and short, no more than 4 cm at any part of the body; the undercoat is thick and woolly: curly hair is not acceptable. White patches in the coat (except for small patches at the chest, abdomen or feet) are not desirable at all, as well as a completely black specimen. The male Chesapeake weighs between 32 and 40 kg, the female between 27 and 35; the male stands between 58 and 66 cm, the female between 53 and 60.
The Chesapeake Bay Retriever needs it’s time to build, and many times it doesn’t reach maturity until after three years. 
The Chesapeake is an athletic, robust dog that enjoys dog and people’s company equally. It tends to play rougher than other Retrievers, but it works as hard as any. It is not a dog to be at home all day, although it loves the time it spends with the family. Outside of home it is cheerful and vigorous. The Chesapeake is more dominant than one would think, for which it is a very good guardian. Training for general obedience and field work can be started early.
Choose a Chesapeake Bay Retriever puppy with wavy hair and soft character. The mother should be balanced in structure and character. 
The newborn puppy weighs between 280 and 500 g. The hind dewclaws should be removed, the fore are optional. The puppies can vary in size, according to blood lines. An eight week puppy can weigh between 4.5 and 7.5 kg. It is a breed that matures slowly, reaching its maximum height between nine and twelve months, but doesn’t reach complete maturity until after 2.5 or 3 years. The puppy is born darker, and lightens to its adult color, which is lighter in the shedding period. The puppy is born with wavy hair, but this disappears and comes back with age. (After eight weeks, we will see wavy hair at the tail, the ears and possibly the forelegs, and generally the more wavy hair it has at this age, the more it will have it as an adult). The adolescent can seem unbalanced, leggy, tall at the back, etc. Usually it eats well, according to its strong growing period needs. The males can prove their authority at that time, for which early education is very, very important. The adult Chesapeake is a calm dog. It is protective by nature, but it usually it won’t show this trait until 18 months.
The puppy lightens gradually with age, and gets its adult color after shedding
Although there is not veterinarian information about this breed, retinal progressive atrophy is known. Entropion has also been observed on young dogs. Hip and elbow dysplasia can be a concern, since it affects many other hunting breeds with similar size. Otitis is frequent in every breed with dropped ears. Veterinarians inform Von Willenbrand disease and cataracts in the breed. The Chesapeake, bred and kept for its superb athletic qualities, is very resistant to illness, and given its strong constitution, it can have a 12 year or more longevity. The buyer should avoid puppies with the tail curled over the back and watch for umbilical hernias. The coat, resistant to any weather, requires little care, although it should be brushed regularly to limit the possible dog odor. Naturally it is a breed that requires a lot of exercise and training.
It is never too soon to begin training the Chesapeake Bay Retriever.
