Be glad that you got your dog back. We boarded our golden a few weeks ago when we went to Vegas. When my wife and I got home her father told us the dog had died. She was nine years old and we took here to this same vet all her life. I think they treated her well, it was just her time.
A few years ago we took her to a different place to be groomed, not a good experience. I dropped her off and they told me to come back in eight hours, like it takes that long to cut some hair. I went to pick her up and I saw them pull up in a van with my dog in the front seat, they never told me that they would be taking my dog to another location. I also had a long haired golden that now looked like a lab, they wanted $60 for the trim, hell I could of done the same job with the clippers.
When we go home she drank several bowls of water, and man was she pissed, she stayed on the porch and would not even come around any of us. Later I had heard from several people that a few dogs have died at this place, not the best news.
Edited to add that now we have a new golden puppy that chews up most everything in our house.
