They are lovely.
All the pups will carry for longhair, unless momma also carried long hair. Longhair is a homozgyous gene, so it must be present twice (ll) to show on the babies. So if mum is short hair, carrying long hair, the babies have a chance to be long hair.
While I'm bad with babies on fur lengths, and it's harder to tell on females especially this young, one cinnie pup looks like s/he may have longer hair... but besides that they all look short haired to me.
