I have recently started taking my 5 month old pup to the dog park when there's no one or next to no one around also. I know there not good places for our breed to be but he needs an open grass/dirt area to run around in and the small space at my appartment gets old to him sometimes. I always try and stay in my "section" of the park far away from the entrance or where most people tend to hang out and let there dogs frolic. I alway stay close by him and if any other dog approaches me or him I always make sure I'm I between them and can intervene if anything seems awry
