The only commands I worry about are, come here, load up, get out and get ahead. I'm probably in the minority on my opinion but I think that too much handle can hurt a dog when it comes to range and staying ability. I will also teach a cow dog, get behind so they will stay with my horse until I send them and back up to give the cattle some room. I like an independent minded dog and don't mind one that is a little hard to catch.
I am with you. I make sure I can grab my dog anywhere. They need to come when I call them. But I want a more independent dog. I have been around dogs with good handle. But when it comes to hog hunting I would say no we all don't know how important handle is in a dog. I would ask what do you mean by handle? I don't want the dog walking beside me for sure. Bird dogs need handle but not hog dogs.
