The chocolate Lab is a Labrador Retriever in the breed's brown coat, one of three colors the breed standard accepts. The breed traces to Newfoundland's water dogs and was refined in Britain as a gun dog, which explains the sturdy build, otter tail, dense double coat and love of water. Adults usually weigh 55 to 80 pounds and stand 21 to 25 inches tall, with brown noses and eye rims.
In McKinney, that retriever background fits a city of creek trails and backyard living. Many chocolate Labs are friendly and eager to please, though young ones can be boisterous and mouthy. They shed year-round, and more in spring and fall, so expect regular brushing. UK research found chocolates tend to have more ear and skin trouble and a somewhat shorter lifespan, so an early veterinary checkup is worthwhile. Each dog's personality and needs still vary.
