I think Silver was a defensive head dog with no finish.ill use him as a example for legal purposes.Pera did add the Spike blood through Hammonds to add finish .Gr Ch kid is a example of what it looks like.Both styles can get you the W though.I have saw some head dogs that will finish in the head your offensive ones.And some move on to the rear.There was a time around here were you could get ear dogs for a little or no money and it was a ear dog with no finish.You might get a ear dog with finish at times but not likely, it depended on what the breeder liked.I got most of mine from a guy who liked leg breakers.
