While a hunting dog is legal (still), adding "features" such as GPS will convert them into "assault dogs" which the libs fear.
Soon you will need to register your pets as "tactical pets". You wont be able to use accessories such as spike collars, paw shoes, snake proof armor, leash restrictions,etc. These animals must have devices installed such as muzzles. Debarking will require a tax stamp from atf&a (animals).
If they had their way, the only feature that they would allow in this state would be the argyle sweater.
I dont have a hunting dog but I feel your pain.
