I have been taking Keegan to the park pretty frequently. At least once a week. And when I don't go to the doggie park I take her to the local park and let her run in the fenced in baseball diamond.

She got into a scuffle a couple weeks ago with Dazzi, Amy's (Cincy'sMom) mom Diane, dog. She is a golden mix and from what they said she has a problem with Goldens and GSP. But of course Diane and Amy are wonderful, responsible pet owners. And quick thinking Amy threw water on them and Dazzi went right into time out, then had to go home I didn't know what to do just chased them trying to grab Keegan. Amy and her mom felt horrible about it and Dazzi isn't allowed at the park when Keegan is there. Which I feel bad about .... Keegan has a scar on her nose that you will soon be hardly able to notice. I just said "Dogs will be dogs and it could have been much much worse." No harm done. But it is different when you have irresponsible dog owners.
We have a lady that brings her little JRT to the park. She only weighs 9 pounds. And another couple that brings their Boston terriers. Like I said everyone watches out for the little ones.
Actaully this couple brought their 2 dogs and their 2 kids and the youngest boy was more trouble then all the dogs together. Getting in the dogs faces and growling at them (did this to Gabby the great dane), taking their toys. Chasing the dogs. Nagging people who were playing with their own dogs, saying "let me let me let me" and when this one lady that has a 7 week old boston terrier that she wouldn't put down on the ground she took her into the time out cage so she could potty he went over and messed with the latch and his mom said "no don't go in there she is in there for a reason" he went on it and picked up the puppy and proceeded to manhandle her until the owner took her away from him. Surprisingly the owners/parents had more control over their 2 dogs then their one son. The other son wasn't bothering anyone and I never heard him say a word at all. It is people that are like that and what you described in your experience that make it not fun for others and will cause people not to come. Very sad.
I am glad Josie is Ok!
