Do dog parks make dogs tired?

Un-walked dogs become: Less social, less friendly to all dogs and humans they know and dont know, less recall, bored and depressed - potentially developing mental issues, Gain weight and harm joints and reduce life, anxious with increased chance of separation anxiety. Not all dogs are naturally confident, Puppy raising issues, breed or other factors can have dogs either be too timid or too aggressive. Both of these things can lead to fight or flight actions by dogs. And even dogs that have become confident because of their off lead dog walks will often quickly lose that confidence when restricted to their yard or only a few walks per week. Dogs are one of the biggest pack animals species on earth, they deserve, crave and need regular contact - preferably daily. Not being around dogs regularly can make the first few times and older dog is exposed somewhat a jarring experience. The trouble I have recently seen with one previous dog park regular is that the lack of walks has now returned the dog to its original anxious and aggressive state.

Our one-year-old dog George has been extremely high energy for the five weeks we've owned him, despite very long walks, mental stimulation, etc. In the last ten days or so, we started taking him to the dog park, and this weekend we took him on a short trip where he spent the entire time out of his crate engaging in high-energy play with a very similarly sized dog. He has slept for the past two days— nearly continuously. On my lap, on the couch, at night, in the morning, through times he would normally wake up to bite at my feet.
