When do Australian Shepherds stop growing?

Most Australian Shepherds reach their adult height by 12–16 months as skeletal growth plates close. They may continue to fill out with muscle for another 6–12 months after that. Females typically finish growing earlier than males.

When should I switch my Australian Shepherd from puppy food to adult food?

For a medium-sized breed like the Australian Shepherd, transitioning to adult food at around 12 months is generally appropriate. Make the switch gradually over 7–10 days to avoid digestive upset.

How much should a 6-month-old Australian Shepherd weigh?

At 6 months, many Aussie puppies weigh roughly 10–20 kg, which is approximately 60–70% of their expected adult weight. Individual variation is significant — the most reliable check is body condition assessment, not a specific target number.

Is it okay to exercise my Australian Shepherd puppy a lot?

Moderate exercise is appropriate, but intense, repetitive, or high-impact exercise should be limited until growth plates close around 12–16 months. Short, frequent play sessions are better than long sustained runs for puppies under a year old.
