Why do we run so many bay dogs?

I like multiple catch dogs for a couple of reasons. #1 reason is that I want my bay dog to leave once the catch dogs catch. Got a couple dogs that you might not see at the catch at all. By the time you get there to leg the hog, and have it tied or stuck, the bay dogs are already a couple hundred yards out hunting again. #2, I have had the hog break after the catch dog was released, only to have it bay up and be caught a a couple hundred yards away in some thick stuff. It took a while to get there, and it was a stout 250# boar, both catch dogs were getting hot, and I was glad we had two catch dogs that day. It's just my preference though.

Like what DJ said, mix it up and have fun. If there is one rule in hog dogging, it's that there are no absolutes!
