This has always been one of my biggest fears , something happening at the groomers

It makes is sick , and very very sad. i hope you do pursue pressing charges against the groomer . i know it won;t bring your baby back , but they are the ones to blame. I have seen the groomers at Petsmart walk away from grooming tables leaving the dog on the table with a strap around it's neck , I was furious .This accident should have never happened.
