Most Shetland Sheepdogs reach their adult weight by around 11 months (48 weeks).
As a small-sized breed, your Shetland Sheepdog reaches adult size by 10-12 months. Smaller breeds tend to reach full size faster than larger breeds.
Individual dogs may reach full size slightly earlier or later. Spayed or neutered puppies may also have slightly different growth timelines. Regular vet checkups are the best way to track your Shetland Sheepdog's progress.

Because Shetland Sheepdogs are a small-sized breed, look for a small breed puppy food designed for their growth needs. Smaller kibble, higher calorie density.
Feed puppy-specific food until your Shetland Sheepdog reaches adult size (around 11 months), then transition to an adult formula over 7–10 days.
