The chocolate Lab is a Labrador Retriever in the breed's brown coat, not a separate breed. Labs descend from Newfoundland's St. John's water dogs and were refined in Britain as gun dogs, which explains the webbed feet, otter tail and love of water. They're large, usually 55 to 80 pounds, with a short, dense double coat that sheds all year and more heavily as the seasons change.
In Corpus Christi, that love of water and activity pairs well with bay and Gulf shoreline walks, though dogs vary and a young Lab may be far more boisterous than a senior. Chocolates in a large UK study lived somewhat shorter lives on average, so steady weight control and routine veterinary visits matter from the start. Many Labs are food-motivated, which makes training easy and weight gain easier.
