Rough cow dogs

I like and use a dog that can get rough but not an alligator unless I'm asking for it. If a dog can get rough it's easy to back them off, if they can't get that way and you need it you can't wish it on them. The number of cows, where they are, and if they have had dogs on them are all factors. Funny thing is all the, cows we gather are " gentle as a milk cow and normally, come right in ". Nobody thinks they have wild or mean cows  when I was younger it didn't get too rough or too wild. Funny how things change.
