I was wondering at what ages labs have growth sperts/weight gains. The reason I ask is because my lab has maintained give or take 2 pounds from age 7 months to now 11 months (69-71 pounds). Is he done growing and gaining weight? Or is he due for another spert?
Honestly, it depends on the individual. Some show lines especially take a long time to mature. Most Labs will be done growing by 12 months give or take but may contine to 'fill out' (gain bone and muscle mass) until they are 24+ months.
