When is a Shetland Sheepdog fully grown?

Most Shelties reach their adult frame by 10–12 months. Full muscular and coat development may continue through 14–16 months. As a small breed they mature faster than medium or large dogs.

How much should a Sheltie puppy weigh at 6 months?

A Sheltie puppy expected to reach an adult weight of around 8–9 kg might weigh approximately 5.5–7 kg at 6 months, though this varies with the individual's frame size and adult weight potential. Monthly weigh-ins and vet check-ins give a more reliable picture than any single target.

Should I feed my Sheltie puppy a small-breed formula?

A small-to-medium breed puppy formula is appropriate. Giant-breed puppy foods are not suitable. Look for an AAFCO statement confirming the food is complete and balanced for growth.

Can I tell how big my Sheltie will get from its puppy weight?

Puppy weight at 8 weeks gives a rough indication, and most small breeds reach about 50% of adult weight by 14–16 weeks. The best prediction comes from knowing the weights of the parents and siblings from the breeder.
