A yellow Lab is a Labrador Retriever in one of the breed's three recognized colors, anywhere from pale cream to deep fox red. The breed descends from water dogs of Newfoundland and was developed in Britain as a gun dog, which explains the dense, water-resistant double coat, the otter tail and the constant urge to carry things. Adults usually weigh 55 to 80 pounds.
Most are friendly, eager and food-motivated, and they do best with people who enjoy training and daily outdoor play. Labs gain weight easily, so measured meals matter, and the heavy shedding continues year-round in a warm place like San Juan. Light coats hide dirt better than black ones, but pale noses can sunburn in strong tropical sun. Dogs vary, so look at the dog in front of you.
