Our first trip was for day care. Our puppy was about 10 months old 35 lbs. she had never been left before but she socializes with other dogs a lot. So I wasn't too worried.
She came home exhausted and soaking wet -- however she came home with deep puncture wounds under her neck that became infected almost immediately and it ended up costing a trip to the vet ER and about $350!
So either there was no supervision or they were really clueless as to the intensity of play time.
I informed the staff and they did call the next day to see how she was doing and offer some free daycare. Have not gone back yet but will not allow her in with the big dogs.
