Signs of Maturity in Labradors

Labradors are the most popular breed in both the United States and Canada, according to AKC dog registration statistics. As they age, Labs demonstrate telltale signs that indicate sexual and social maturity. These signs can indicate the dog is advancing gracefully or it may be in need of veterinary care. Signs that the dog is developing social disorders, including anxiety, aggression or fear, are apparent during its social maturity stage. Be diligent about caring for older, mature labs to prolong their life expectancy.

  1. Sexual Maturity

    • Labradors can come into heat for the first time as soon as 8 months old. Signs include swelling of the vulva and bloody discharge, as well as attentiveness to male dogs. A Labrador can stay in heat for several days; keep it away from other dogs unless you schedule a breeding. Heat will occur twice a year. Recommended breeding age for Labs is after the dog's second birthday, when it becomes socially mature.

    Social Maturity

    • Signs of social maturity include obedience and loyalty. Labradors socially mature between 18 months and 3 years old. By this age and with consistent, quality training, Labs learn basic commands, become completely house-broken, know how to interact correctly with other dogs, and have settled into their place within the family. Dogs that experience incorrect training or emotional triggers will begin to show signs of anxiety or aggression. These signs include biting, barking, pacing, chewing and other destructive behavior.

    Physical Maturity

    • Labradors reach adult age after 3 years of age. Signs that a Labrador is an adult include weight and height; when a lab weighs between 55 and 80 pounds and stands between 21 and 24 inches tall, it is most likely an adult. Labradors are prone to obesity and require regular exercise. For best results, begin training your Lab before it reaches physical maturity.

    Signs of Aging

    • The average life expectancy for Labradors is between 10 and 12 years old. Signs to look for in older Labs includes graying in the facial area, enlarged elbow pads and warty growths on the foot pads. Labs can also develop fatty tissue under the skin. Notify your veterinarian of any concerns, including unusual fatty tissue lumps, stiff joints that could indicate arthritis, excessive weight gain, breathing problems or sudden socialization disorders.
