I would LOVE to see dog parks in Tulsa! There is already one planned in Mohawk park as part of Vision 2025, and I am extrememly grateful for this! However I would also love to have another one closer to where we live.
As far as all of the nay-sayers re. off-leash dog parks, if you do the research you will find arguments on both sides of the fence agreeing and disagreeing with your concerns. (Frankly, those with the most knowledge of animal behaviour (trainers, etc.) are the least concerned with the safety issues.)
Therefore, I can only speak from my own experience. Many outdoor-friendly communities throughout the US have off-leash dog parks. (The OKC area had 3 or 4 the last I checked - see http://www.pawok.com/ to get a taste of the fun.) The ones I have gone to are an absolute joy to visit! This is what I have found:
1. I have never seen dogs get angry with one another. This goes right along with comments I've heard trainers make that dogs off the leash feel a sense of control with their environment, and therefore feel less of a need to try to take control (in the form of aggression.)
2. Owners are customarily very considerate about picking up after their dogs - and for the small minority who aren't, they are either asked to comply, or others will simply pick up after them (out of respect for the park.) Those who are conscientious enough to make a trip to the dog park are generally those who will take the time to be responsible with these types of things.
3. Yes, the dogs will bark, but it isn't the major barkfest that some people think it might be. :) And more often than not, it is a bark at their owner to hurry up and throw that frisbee already!
4. There are generally signs posted that people enter at their own risk (most dog parks are entirely fenced) - the city's way of covering itself. Also, that owners are held liable for any injury their animal might cause to another - therefore discouraging those who might have a very aggressive dog from entering. However, again, I've never seen or heard of a problem with any of this.
I could go on, but I might put you to sleep so I'll stop here. :)
I must say when I first heard of an off-leash dog park, even though I am a huge dog-lover I also had the exact same missgivings I'm reading in this forum. Those fears were absolutely put to rest with my first dog park visit. I feel it's pretty safe to say that after people become acquainted with, and educated about, off-leash dog parks, they will be bringing fido along for the fun with the rest of us!
So I say, more power to you, for those who are advocating this wonderful addition to our beautiful city!
