Monitor your puppy's growth with an individual growth chart
Small breeds (under 10 kg) are fully grown at 10-12 months. Medium breeds (10-25 kg) at 12-15 months. Large breeds (25-45 kg) at 15-18 months. Giant breeds (over 45 kg) at 18-24 months. Growth rate is highest in the first 6 months.
Rule of thumb: At 16 weeks, a puppy has reached about 50% of adult weight for small breeds and about 30% for large breeds. The weight at 6 months roughly doubles to adult weight in small breeds and roughly triples in large breeds.
Signs of too-rapid growth: bowed legs, stiff gait, lameness, swollen joints (especially wrists). Large breeds are more susceptible. Overfeeding and excess calcium are common causes. The puppy should be lean with easily felt ribs.
