Saluki Cross Dark Blue Whippet Pups

Mum is half whippet half saluki and the father is a KC reg slate blue whippet making the puppies 3/4 whippet 1/4 saluki.
Pups look black in the photos as still young but seem to be lightening up to a slate blue. Most pups have a white chest marking and the odd white foot. Happy to send more photos and videos of parents and puppies if interested.
