We go to the Darien Animal Clinic too and love them. They are very accommodating for all 3 of my dogs. A little pricey, but worth it.
I took my last dog to Downers Grove Animal Clinic where they missed two hernias she had that required surgery. I boarded the same dog at the Downers Grove Animal Hospital shortly after her surgery and when I picked her up it seemed that she was left in her cage the whole time because her whole back end (including the stitches) were soaked with urine. Finally we ended up at West Suburban Animal Clinic in Westmont where they missed a heart problem in my dog, that lead to her death shortly after.
So, I've been around to different vets and the Arboretum one or the Darien Animal Clinic would be my recommendations.
