bought two dogs out of Oklahoma to mix with my silent bay dogs. They will shut down a runner and latch on. one will catch on the ear the other will catch on the back leg. One is full blood blue tick and a big one! He has a loud mouth, but is fairly silent until he gets excited. The other is a mix cur. both are about three to four years old and male. You must run vest. First time I took them out we came out with three hogs on a short run, but had to put 10-15 staples in, we did not run a vest. They are both healthy and hate a hog! $1000.00 for each. 870-918-9425 can txt or leave message.
