My little girl, Jasmine, also has a mild form of this condition. She is eight years old and doing very well, I'm glad to say, but the first couple of episodes scared half the life off me - she just stood there with her sides heaving, struggling to breathe.
I'd go with the advice you've already been given - no collars and keep your furbaby in good health. I've seen a noticeable difference in Jasmine's condition between the summers she goes hiking with me (yep - all five pounds of her) and the summers we don't get out as much. An example thats slightly off topic, but illustrates the benefits of keeping our babies in good health: Jasmine developed something similar to a pinched nerve condition that the vet thought might require surgery to repair two winters ago. We decided to wait and watch for awhile and shortly thereafter I was laid off from work. All that spring and summer we hiked two or three times a week, from three to six miles each time. By the following fall, Jazzy no longer had that painful pinch, and we haven't seen it since.*yeah!!*
From my experience and others, I'd say you have a long, fun yorkie relationship to look forward too. Good luck, Debbies, and welcome to the wonderful world of Yorkies!
