My dog was attacked here

This photo was taken at The Deuce of Dogs Bark Park in Show Low, AZ. My first experience here was horrible; my dog was attacked by three Irish wolf hounds in the social off leash area there were two grey that did the attacking and there was also a white one. The man was driving a white ford f150 with a white camper I went home to assess the injuries and take photos, I went back to the park in hopes of getting any information and he was no where to be seen, if anyone has any information please message me at ny Facebook Tyler Lincks my photo is of me and my fiance, the park sign specifically states NO AGGRESSIVE DOGS ALLOWED.
