Labrador retrievers, long among the most popular breeds of dog worldwide, are known to be gentle and easy to train. They're also high-energy dogs who require frequent physical and mental stimulation to prevent boredom and poor behavior. The American Kennel Club calls them ideal family pets. Their strong and sturdy bodies reflect their status as purpose-bred working dogs.
According to the American Kennel Club, Labrador retrievers are medium-size and short-coated breed. An adult female grows to a height between 21.5 and 23.5 inches at the shoulder. An adult male grows to a height between 22.5 and 24.5 inches at the shoulder.
Healthy adult male labs typically weigh between 65 to 80 pounds. Average adult female labs weigh between 55 to 70 pounds. In order to maintain their weight, labs require at least 40 minutes of exercise each day. The Lab is prone to obesity. If you can't feel your dog's ribs through his coat easily, he's fat. Consult your vet to dial down the dietary intake.
