Mud puddles are Lab magnets. Cracker relishes any opportunity to disport herself in cool, clingy slime. Anything we regard as gooey, messy and dirty she sees as puddle-luscious. Luckily for us all, a Lab's coat is relatively self-cleaning. She does require regular brushing, especially if she's not been swimming in a day or so, because she sheds quite a lot.
Labs are workaholics.
While they can be lazy hounds when there's nothing to do and just lie around getting fat, they enjoy having a job. If you hunt, your Lab will love to retrieve. If there's any other suitable job, he's ready for it. For example, you may want him to retrieve your newspaper. If you take your Lab out for an early morning walk, dress appropriately.
