As far as having numerous dogs out at once, I don't hunt like that and never will, but some guys do. To me its all about the dog doing a good job. If I have 1-2 dogs out I KNOW which dog is doing what. With 8-10 dogs out I feel you are just hoping something out there can get the job done.......it doesn't take that many dogs to find/bay a hog....ever.
Most guys just have no confidence in their dogs. Of the guys that hunt packs of dogs, how many will load up ONE of those dogs and drive an hour or more to hunt, and NOT take any other dogs?? Very few I bet. If you would do that, hunt one or two dogs at a time, you would soon learn what dogs are doing the work, and which dogs are just along for the ride........
Personally I dont hunt that many dogs on the ground but just because you do dont mean any one of the bunch cant get it done. With todays technollogy I could have 8 dogs on the ground and pretty much tell you when one has stopped to take a number 2. I know Jessie hunts several dogs sometimes and I can gaurantee you none of them need any help. Its just what you like. You dont like it but some do. I dont really agree with hunting a couple of rough dogs with no catchdog to back them up. But some do.
