Puppy adult size prediction estimates final weight from current weight and age. Large breeds grow longer than small breeds and need different multipliers.

Wzór

Często zadawane pytania

Is there a better way to estimate adult size?

Breed standard most reliable. Parents' sizes. Growth charts: most puppies reach 75% adult weight by 6 months, 90% by 9 months. Large breeds grow until 18–24 months.

Why does formula become inaccurate?

Growth non-linear. Fastest month 2–3; slows month 4+. Large breeds plateau slower. Nutrition affects growth rate. Weight at 16 weeks better predictor than week-by-week formula.

When is dog fully grown?

Small breeds: 10–12 months. Medium: 12–15 months. Large: 18–24 months. Skeleton plates close later in large breeds. Continued growth past 12 months possible.
