Does that park not have seperate area for large and small dogs? I have only taken mine once and that was because we were away from home and they were having to spend a lot of time in thier crates while at families homes. The did have a seperate area for dogs over 25 lbs. Most of the time we had it to ourselves but after a while a lady came withe her dog probably 12-15 lbs and was fine unril honey got nervous and started to run from him. Then he took chase and she was scared to death. No big deal, no fighting or anyone hurt but I would never take them in a normal situation just due to what "could" happen and doggie diseases even though the are vaccinated.
Hear way too many horror stories about them.
I hope you are both ok and I am so sorry you got bitten.
