Predict how big your puppy will get based on current weight and age. Works best with breed information.
Puppies grow at different rates depending on their breed size. Small breed puppies reach their adult weight quickly, often by 10 months, while giant breeds may continue growing until they are 2 years old. Knowing your puppy's expected adult size helps you plan for proper nutrition, equipment sizing, and healthcare needs.
Adult by 10-12 months
Adult by 12-15 months
Adult by 15-18 months
Adult by 18-24 months
A common formula: Adult weight = Current weight ÷ Current age in weeks × 52. However, breed size matters - toy breeds reach adult weight by 10 months, while giant breeds may grow until 18-24 months.
Small breeds stop growing at 10-12 months, medium breeds at 12-15 months, large breeds at 15-18 months, and giant breeds continue growing until 18-24 months.
Predictions are most accurate for purebred puppies. For mixed breeds, look at paw size and parent weights if known. Predictions become more accurate as the puppy ages.
Factors like nutrition, health, genetics, and whether they're neutered can affect final size. Proper nutrition is crucial - both underfeeding and overfeeding can affect growth.
No, overfeeding can lead to orthopedic problems, especially in large breeds. Feed according to guidelines and let your puppy grow at their natural pace.
You should feel ribs easily without pressing hard, see a waist from above, and see an abdominal tuck from the side. Your vet can assess body condition score.
