How Puppies Grow
Small dogs reach full size quickly (9-12 months), while giant breeds grow until 24 months. The most accurate prediction comes at 16 weeks, when many puppies are roughly half their final weight.

Pro Tips
Between 4-10 months, puppies often look lanky and disproportioned (the 'ugly duckling' phase).
Large paws don't always mean a large dog; some breeds (like Bassets) naturally have huge feet.
Limit high-impact exercise until growth plates close (12-18 months) to prevent joint issues.
Giant breed puppies need specific food to prevent their bones from growing too rapidly.

Fun Facts
"Small breeds reach 50% of adult weight around 4 months; giant breeds take 6-8 months."
"The 'spay/neuter' timing can affect growth; early fixing can cause growth plates to close later, leading to slightly taller dogs."
"Puppies may sleep 18-20 hours a day because growth hormone is primarily released during sleep."
"A Golden Retriever's 'teenage' phase is usually between 6 months and 18 months."
"Most dogs reach their full skeletal height months before they 'fill out' to their final adult weight."
Formula: Adult ≈ Current × (Full_Growth_Weeks / Current_Weeks)
