OMG, that looks like such fun! I too wish my city did more doggie things. I swear I would take my babies with me everywhere if I could. I hate when we have to leave them at home.
A small town near here had a Bark in the Park a few years back; nothing like this one, it was in a little park with not even 100 people & dogs. It was fun, but they haven't done it again

Our humane society holds a couple of dog events maybe twice a year....but that's about it.
Glad you all had a good time and got to meet one another & the furbabies. Love the pics!
