Size

• "Labs" average 50 to 75 pounds at full growth. Male dogs average 65 to 80 pounds and females 55 to 70 pounds.
  
  

Time Frame

• Labrador puppies usually reach their adult size at about 14 months, but they continue grow until 18 to 24 months, according to Club Labrador.
  
  

Considerations

• To monitor growth, weigh your puppy every week. Switch to food with more protein if he seems hungry all of the time.
  
  

Misconceptions

• Labs need puppy food until they are at least one year old. Puppies need three meals a day. Follow the feeding rates listed on the puppy-food packaging, as different feed companies use different formulas.
  
  

Warning

• Monitor your puppy's growth. If it grows too fast, it may experience pain; if it limps or whimpers when it walks, see a veterinarian immediately.
