Information on Sheltie Pups

[bam60]

We have a new sheltie pup and we are wondering how old before she fills in her mane.

[Aztec]

I have a sheltie male that is about two years old. His coat came in at around 1 year or 1 year and a half. Aztec's sisters coat came in around 8 months so it varies from dogs. And males generally get their coats later then girls.
