How big does a Rottweiler get?
An adult male Rottweiler usually weighs 95–135 lb (43–61 kg) and an adult female 80–100 lb (36–45 kg). Rottweilers are slow to mature and can keep adding muscle until 2–3 years. Large-breed puppy food helps control growth speed.
When is a Rottweiler fully grown?
As a giant breed, a Rottweiler typically reaches its adult weight at about 24 months. Height usually finishes first; chest and muscle keep filling out for a while after.
