Cow Dog Question

Gomer we need to get together and work our pups. Mine tend to work on one single cow causeing her to break out and hole up, but are getting better. I am working on their back up also and let em settle. Had some bucking stock get in with my cows the other day and one of pounded both pups pretty hard. I tried to get em out before they got hurt bit both wouldn't let up. I was glad to see they didn't quit. I was able to get the bucking bulls out let and move them around and pen em. I also got to send em to one bunch call em off and send em to the other bunch which was their first time dining that.
