my trainer suggested that i don’t, but i think that if ur dog has been well socialized to play well with other dogs it should be fine. i’ve only had my pit since last october and she’s 2 years old, i’ve tried to have her play with other dogs but she has shown some anxiety around larger dogs, and bullies the smaller dogs. i prefer to exercise her by taking her on walks and i take her to forest preserves where i know she can have fun and usually avoid dogs. my thing is that i know she has had issues with other dogs so i try to set her up for success. but once again if ur dog doesn’t show any of those issues i don’t see why not, it’s mostly all aabout knowing ur dog, and controlling the environment as much as possible to have a happy fun trip to the park.
