Update: My dog has attended a day care at a different facility for the last 5 months. There have been NO issues and NO injuries. The staff rave about what a sweetheart of a dog he is and report they have never had a challenge with him. We also spend time at the city off leash parks with no issues.
After my dog received these injuries at D.O.G.S, I asked specifically if he had ever shown any signs of aggression and was told "no". This is also the first time I have heard someone reference what happened as a "fight". Perhaps if staff would have been open to communication throughout this incident we both would have stronger understandings of what really happened.
Please be careful where you leave your pets. No matter where you are considering... Research, Research, Research!
