Why do people use help dogs?

To me a good help dog is not a strike dog but a dog that runs with the pack and is good about stopping the hog. Instead of having a 2 or 4 hour race these type of dogs will stop the hog within 1 mile if they can catch up. These are not running catch dogs but extra gritty/rough pack dogs.

It is kind of like a football team. It takes different types to make a top rated team.

I had 5 to 7 what I considered to be top strike dogs that would hunt as a pack or by themselves and I caught lots of hogs with them but sometimes it was a good ways to the bay. A friend of mine uses several of these purebred dogs but will breed pit, cat, bmc in about half of the pack. He catches as many hogs but the races tend to be a lot shorter because of the pit blood.
His pack dogs vary in hunt, some have a lot of hunt and then others don't hunt but run with the pack and help stop a hog.

I wouldn't keep a pack dog that can't find a hog.

I would keep a pack dog that will hunt if if it isn't a real good strike dog as long as it helps in making the races a lot shorter.

As the population grows and the hunting land gets devided into smaller tracts then it only makes sense to start breeding strike dogs with the same traits as a good stop dog. I have had dogs with lots of grit but I have seen pack dogs that were way better at stopping a hog.
I used the words "me too dog" and "pack dog" I reckon it is another way to say help dog.
