A & C, your link looks fabulous!!
We have been doing that, we live within 10 minutes of 2 dog parks. He was okay at first but once a dog came towards him he was terrified and started barking so I calming walked him away and finished our walk on a positive note. He can watch dogs from a distant, and I've got were 95% of the time he wont bark at another dog if they start barking. He is very reactive to another dog barking if they bark he barks and wont stop. But thats under control so we are working watching dogs from a distance. He is completely fine with other dogs as long as we/they approach from a angle and not straight on, still nervous but doesn't immediately bark at them. Such an improvement. He is more fearful/anxious with a larger dog, like a lab, or a pit bull. He's tucked tail and wanted to run from a few pits on our walks. So I think the small dog park would be best at first. We will hopefully be going tomorrow.Since Remi had such a good experience tonight, maybe doing some work with him at a distance outside the dog park might be beneficial, get him used to being close to other dogs, lots of click/treating for nice, calm behavior for seeing other dogs (I've logged in soooooo many hours doing just that). In doing so, you might meet someone (another dog) who you know Remi could play with (Remi will tell you) and they could then go in and play. Just a thought. Good luck!!
