The Chesapeake Bay Retriever is classified by The Royal Kennel Club as a large breed, typically weighing 25–36 kg as an adult, with a median life expectancy of around 11.6 years, according to a 2024 analysis of UK veterinary records by Dogs Trust. Developed on the Chesapeake Bay in the United States to retrieve waterfowl in icy conditions, the breed has a distinctive wavy, oily coat that sheds water effortlessly and a determined, independent character.

What this means for your Chesapeake Bay Retriever

Hip dysplasia and progressive retinal atrophy (a gradual, inherited loss of vision) are both worth screening for, particularly if you're getting a puppy from working lines. The breed's dense coat can also trap moisture against the skin, making it prone to hot spots if not dried thoroughly after swimming.

As a working retriever bred for stamina, Chesapeake Bay Retrievers benefit from staying active well into their senior years, with exercise scaled back gradually rather than stopped abruptly.

When is a Chesapeake Bay Retriever considered a senior?

Under The Royal Kennel Club's size-adjusted guidance, large breeds like the Chesapeake Bay Retriever are generally considered senior from around 5 dog years old.
