Good hard hitting curs!! We also use Blackmouths, catahoulas and Lacy dogs for catching jobs. I have a 16 ft S+H THAT IS PRETTY RAGGED. If you want to see the best built cowcatching trailer made, go to bigbendtrailers.com. Im sure you do have some cow stopping dogs, as I have also caught cows on small places, pain in the a_ _  if you dont have room to run the fresh off a cow before she hits a ragged old fence, and you have to rely on dogs to bay her up first. Sorry, I get long winded sometimes.
