Is she more Sheltie or more Cocker? That sounds like an interesting combination.
I don’t know how to post photos otherwise I would show you. Initially, you see the Sheltie: the longish hair, the curly-cue tail, the somewhat pointed snout of a collie. But the rounded head, the (somewhat) bulbous but beautiful black eyes and personality are Cocker Spaniel. I tend to see the Spaniel as does my husband. My mother sees “a collie.” She has a sweet nature and a gentle soul.
My last dog was a black lab. A complete nut case who we loved and miss terribly.
