The Critical Role of Breed Size
Puppies do not grow at the same rate. The growth factor is tied directly to the final adult size, with **small breeds maturing much faster** than large or giant breeds.
- **Small Breeds:** Typically reach 99% of their adult weight by **6-8 months** of age.
- **Medium Breeds:** Usually finish the rapid growth phase around **10-12 months**.
- **Large & Giant Breeds:** Continue growing significantly longer, often not reaching full adult size until **18-24 months**. Monitoring their growth rate is crucial to prevent bone and joint issues.
Remember that nutrition during the first year is vital. Consult your veterinarian regularly to ensure your puppy's weight is on track for their expected adult size.
