mugsy, I've looked at Foxy again...& she's very, very like a Pharoah Hound.
Is there a breeder of Pharoah Hounds that would be willing to have a look at her to say if she's one or not? At the least, she could be a Pharoah Hound cross.
The breed is often called the Egyptian Pharoah Hound...but it's actually the national dog of Malta, the island country in the Mediterannean. There would be Pharaoh Hound breeders in the US...it's described on the American Kennel Club site. It's not a common breed but it has a distinctive appearance...& Foxy has some of those characteristics.
