Large breeds are powerful, athletic dogs that typically weigh between 60 and 100 pounds at full maturity. Recognised across
many AKC groups — working, herding, sporting, and hound — large breeds require careful weight management throughout their lives due to the significant stress their size places on joints and organs.
Large breeds take considerably longer to reach their full adult weight than smaller dogs, often not fully grown until 18 months
of age. Puppies of large breeds should be fed large-breed specific food to support controlled bone development and reduce the risk of hip dysplasia and osteochondrosis. Using an accurate large dog weight calculator for your exact breed is the best way to stay on top of their health at every stage.
Key characteristics of large breed dogs:

- Fully grown between 15–24 months
- Higher risk of joint issues — weight monitoring is critical
