who breeds true rcds

Thats a 7 month pit. dad is on the second pic and mom is the female with her in the kennal. As you can see by the pup they came out real leggy and the first litter my Male and female put out all came out to be jam up catch dogs that have run on the ground and can easily keep up with the curs. They have all found a hog on their own from the parents to the first litter. First time they ever did that I thought they were fighting cause all I heard was a big fight and the only ones were the dad and mom in the woods, ran and got there and had a big boar caught.
