Well, you are almost right, except that I have never owned a colie, I do think they are good dogs. I m old fashioned enough, I had a German Shepard as a kid growing up and later had two more that were great. And when it came time to get my Son a dog, a Golden Retriever, which are so good natured.
Its a little like when I go to our bakery here, they've got chocolate chip cookies and then a bunch of also rans, cant even tell you their names.
I don't have a dog and don't want one. I'm through raising babies/kids.BUT, I'm partial to Labs, my daughter has 2 of them.
We've got enough dogs in the neighborhood that my wife carries dog treats with her on her walks even though we don't own any. Oddly, my wife had several dogs but she never raised any from puppyhood (all adopted as full grown). Our neighbor has two great pyrenees puppies. The day my mother died our neighbor brought the puppies over (you need puppies). They're still puppies but one is pushing 90 pounds now.
