lbsUnderstanding Puppy Growth
All puppies go through periods of rapid exponential growth, usually peaking between 3 and 5 months of age. During this window, their calorie requirements are massive. After 6 months, the growth rate begins to plateau.
An old wives' tale says you can tell how big a dog will get by looking at their paws. While partially true for bone structure, tracking their weekly weight gain against a standardized breed curve provides a far more mathematically accurate prediction.
Notice that your dog might stop growing taller at 12 months, but will continue to gain weight. This is because skeletal maturity happens first, followed by muscular maturity ("filling out the chest"). Giant breeds spend an entire extra year just gaining muscle mass width-wise.
