วิธีการคำนวณ Dog Size

Puppy adult size prediction estimates final weight from current weight and age. Large breeds grow longer than small breeds and need different multipliers.
สูตร
Adult weight estimate from puppy: current weight / age in weeks × 52; Assumes linear growth (less accurate after 4–5 months). Breed-based estimates more reliable.

คำถามที่พบบ่อย
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.
