Here is a place to start at least you can find out the laws in your state. I was thinking of getting a beagle to do the same and it looks like i have to:Tennessee- You must first contact the regional office of the wildlife resources division before beginning any tracking operation. The dog must be on a leash. No weapon is allowed to be carried during any tracking operation. You may track at night.
I think you live in Co. if so:Colorado- No tracking allowed as of 2005,
