Here's a link that shows the current regs for each state......Click on the drop down box and you can switch from state to state. They all have rules that are a little bit different from each other. A lot of them only make sense on paper in my opinion. Having to keep a dog on lead because your afraid the it may bark and run after a hurt deer just doesn’t make a whole lot of sense when you get in the field and see things actually unfold. The real reason is not about tracking but more about not wanting to open a can of worms for dog running…..Its just not the same game but leashes is how they want to go about distinguishing the difference. Again, I think these are rules being made by a bunch of folks with no experience in the matter
