Rottweiler Growth Chart

Expected weight by age, week by week

Rottweiler puppies grow at a fairly predictable rate as a percentage of their eventual adult size. Use this table as a general guide - every puppy is different.

These figures are typical ranges based on Rottweiler's adult weight range, not a diagnosis. Genetics, litter size, and nutrition all affect individual growth. If you're concerned about your puppy's weight, check with your vet.

Common questions

How much should a Rottweiler weigh at 3 months old?

At around 12 weeks (3 months), a Rottweiler puppy typically weighs about a third of their eventual adult weight - roughly 16.5–19.8 kg for males and 11.6–15.8 kg for females, based on this breed's adult weight range of 50–60 kg (male) and 35–48 kg (female).

When does a Rottweiler stop growing?

Most Rottweilers reach close to their full adult weight by around 12 months old, though large breeds can continue filling out in muscle and chest depth for several months after that. Larger breeds generally take longer to fully mature than smaller ones.

My Rottweiler puppy seems small/large for their age, should I worry?

Individual puppies vary, and these figures are typical ranges, not strict rules - genetics, litter size, and nutrition all play a part. If your puppy is well outside these ranges, gaining or losing weight rapidly, or you're generally concerned, check with your vet rather than relying on any online chart alone.
