I took Oliver to the dog park the first time too last week. He is 7 months as I waited til 6 months mark to give him his rabies shot. Before the park, He only got to see and briefly greeted other dogs when go to the pet store, on walk and played with my friend's dog occasionally. He was in doggy heaven at the dog park. He wasn't shy for sure. He loves other dogs and human so I didn't have the problem of him barking. He just needs to learn to play appropriately more since there were two out of 5 dogs there that weren't friendly when he came up to them. Probably he got in their face, so he will just have to learn as I take him more. I try to do it twice a week.

Now your Leo seems like he needs sometimes to adjust. I think you should start small, avoid crowded hours for now, better for him and I think other dogs owners may think his barking (out of weariness maybe) is aggression and not like it. Good luck.
