Try Violater 7 for k9's. I used some this last season and the foxes liked it. It has fox, mink, and some other glands, plus skunk for long distance call. Caven's red fox gland lure is also good stuff.
I see MTP also now has Stef Forget's lures- try Cachottier and his mink lure. The mink lure is a good k9 lure. You also can't beat his coon lure.
