There is no reason to require a dog to get accredited unless they just want to. Word of mouth will keep the bad ones from working. Keeping the dog on leash is the only way to keep the conflicts down. Not every person is going to go out and get a tracking dog to just track for themselves. The best tracking dogs after the basics are put on them in training take lots of track under a lot of different situations, that is how they learn. Even in states that have allowed tracking dog for many years it is not like there is a tracking dog on every corner. Even here in Ga were we have been allowed to use tracking dogs forever there are still areas that the closest tracking dog is well over an hr away.
"I want trackers, both handler and dog, to be certified as trained by an accredited training program and licensed by a governing body."
One way this could occur would be to pattern it after New York were the handler has to pass a written test and the handler and dog apprentice under a skilled handler and dog. The problem would be getting those first ones so that they could train the others. Also organizing how these people are going to meet and work together and who the certifing organizatioin is going to be.
I know this is Ga but let me tell you a little about our set up for tracking dogs. There is a list that a state hunting magazine runs twice a year just before hunting season then another online. This list is broken down into the counties so that you can find the tracking dog nearest you. The list averages about 70-75 or so trackers a year. The guys at the top that are in prime areas with good dogs take anywere between 60-100 calls a year. The bad ones only take a call or two and quickly get off the list as they no longer get calls because word of mouth has shut them down. Average areas the good ones get 20-30 calls a year. Everyone is worried about money. Again this is up to each person. Some want to try and get rich, know what, they might take a few calls but it is that person that charges a resonable rate is the one most are going to call. You have a guy who drives 30 minutes to and hr. or more, then spends 2-3 hrs with you tracking what is it worth. Not to mention if it is like me when I get calls at 11:00 at night to come out and help track. Those next days at work are ruff.
Here is a link to the online list of trackers, some have listed what they charge.

Illinois legalized tracking dogs a few years ago and the only requirment/qualification was if it was going to track on state grounds. Then it is required to pass a tracking test administered by an organization, usually one of the breed clubs or something like that.
Here is the link to state regulations off the UBT web site. Click on any of the green states to see how they handle tracking dogs and what they allow while tracking.

Spend the time doing a little research to see how things have been handled in other places before you point blank say no or demand something. You might just find one of the other states has already tackeled your concern or thought. Then voice any of those concerns or thing you would like to see included to the DNR. Make this a good rule change that works for the hunters of Iowa. Make it reasonable so that people will be incouraged to get involved.
