Thanks everyone, I am enjoying her more than I thought possible!
@ Mary Ann, I've moved out to Sherwood Park now, but was born & lived most of my life in Edmonton. What a small world!
Just had our first visit to the vet for our post-adoption checkup. Revising the breed: my vet sees no border collie or other herding breed in her, the body type, stance, etc... is all wrong. She's put her primary breed as Finnish Spitz (which is funny, as that's the first thing I thought when I saw her), secondary ... well ... maybe some Keeshond, Samoyed, other European breed, and agreed with my assessment - who knows? She only weighs 22.2 lbs. (You're right, Phyrie, "Black Pound Hound"

LOL)
Otherwise, she's very pleased. Jinx is healthy, alert, and happy! She thinks I'll have a lot of fun training her, and that she'll learn quickly! So all is well.
