A friend of mines used this keep for a while, he was down in the South part and thought it would be better Keep to use as opposed when he lived up north. He always had 3 parts of his yard, he ran Jeep/Sorrells and also ran heavy Eli dogs and last part of his yard he used some Snooty stuff that he tested and kept to breed into his other dogs. No lie we talked about this very keep about a month ago, he said the keep was great with his Jeep/Sorrells dogs but he lost all the time with his Eli dogs on this keep. Interesting his Jeep/Sorrells dogs were head dogs who just stayed out front riding the head with minimal contact and his Eli dogs were rough hard punching wrestlers. The keep was all cardio and took the strength from the dogs. I know they say every keep is different for every dog but this was experience of one man who used this keep as his primary for a few years.
