I'm so sorry to hear about the dog that escaped and was killed on the freeway. Such a tragedy! Many years ago we had a dog who was an escape artist run out our front door in a split second and get hit by a car in spite of our family's tremendous efforts to prevent it.
I have no doubt that "At Your Service" will improve procedures, training and security to stop this from ever happening again. I have had my dog and grand-dog groomed there for ages without a problem.
