My Lilly has hip dysplasia too. She is three years old and was diagnosed at 18 months. Thankfully, hers was not advanced enough to require surgery. With good exercise (walking), a dramatic weight loss (could stand to lose some more probably, just like her mom ) and quality food and supplements, she isn't even requiring medication for pain.

I hope your Dasher will get a good report and that you will be able to manage the situation without surgery.
