I am against deer hunting with dogs. It is now illegal here in Texas to hunt deer with dogs. Before I go further I will say that I back your right to hunt with dogs IF it is LEGAL where you hunt. I think that the best place to change things that we don't like is at local public forums, where law changes are discussed.
My number one reason for not liking dog hunting is more of a gripe against the OWNERS, not the dogs! Before it was outlawed in Texas, a lot of these hunters would drop off their dogs on one side of someones property and then drive around to the other side and wait for the dogs to run the deer to them. This is trespassing, but then how many dogs do you know that can read signs and figure out property boundries?
As to the relation between deer hunting with dogs and bird hunting with dogs, they are not the same. When you are bird hunting and even rabbit hunting too for the most part, the dogs are almost by your side, under complete control, they are not running lose to ruin other peoples hunt. As I said though, if it is legal and you keep your dogs on your land, then have fun! I'm just glad they finally stopped it here in Texas!
