Hello Jan, Don't know if you got a previous message I sent about an ES female that is in the local pound. The owners who dropped her off told the pound she is an ES, the pound people hadn't heard of ES's and said "ES? She looks like a collie/Aussie cross." The dog in question is a 2 1/2 year old spayed female. I went and looked at her yesterday, she's tricolor, but she has one blue eye. I couldn't remember if this is an ES characteristic? I think the blue eye is what made them call her part aussie. She seems like a sweet, quiet dog, pretty but overweight. If you want to know anything more, please let me know. I am assuming if the owners said she was ES, she probably is (there is a breeder up north of here, but ES's are rare and as I said, the workers at the pound hadn't ever heard of them). The reason the owners gave for taking her to the pound was that they were moving and couldn't take her with them. Dotty H.
