Labrador retrievers are eternally puppies. They love to play, to eat and to make friends, as their cat-scratched noses attest.
Labs’ high energy levels can cause restlessness, and trouble, if they are not provided near-constant entertainment well into adulthood. Meanwhile, some medical conditions can make the already restless breed more so.
Labradors are natural workers, bred to have the stamina to work long days. They initially helped fishermen retrieve nets from cold waters.
