Many dog parks are part of larger park systems, so walking your dog, running, biking, or other activity with them, can usually replace your time at the dog park quite easily without even having to go somewhere new. Training is also an option. Working outside the dog park and using the dogs and the park itself as a distraction is how trainers use dog parks. They can be great for training when used in that manner. Hiking and long lines are also both great if you feel your dog isn’t getting the kind of freedom you want to provide. Freedom without structure isn’t a good thing though, so it’s best to make sure your dog has been trained to a level where they are reliable in these scenarios. When your dog then rushes over to a new dog, call them to you. How many times do you have to say their name before they come. Dogs quickly learn that there are little if any consequences to what they are doing in the dog park, and this is a place where humans are not in the picture.
