It’s important to remember that Rottweilers, like all the large and giant breeds, grow quickly at first but take much longer to mature (and reach adulthood) than the medium or smaller breeds.
Although many Rotties will reach their adult size by around 2 years of age, sometimes it can take up to 3 years for them to reach their full adult size, this is especially true for the large, males.
Never be tempted to try to make your Rottweiler puppy grow faster, or bigger, than comes naturally. This can lead to all sorts of problems including bone/joint conditions and heart problems.
Your pups eventual height and weight is mostly determined by his genetics ie. the size of his parents and even his grandparents. A good nutritious diet and proper veterinary health care contribute as well, but genes are the biggest factor in determining a dog’s conformation.
It’s completely normal for an adolescent pup (anywhere between 12 weeks to 2 years) to look lean as he grows. A pup gains his full height quite a bit earlier than his full weight or muscle development, as long as he’s eating a premium puppy food, and getting enough exercise and proper veterinary care, then he will grow to fulfil his potential.

I definitely need more photos (I’d prefer at least 6 clear shots of each dog taken at different ages), and I’d LOVE to see some ‘girls’ on here, so let me know if you’d like to take part 🙂
