Places where hard dogs are needed, I would take hard dog or a bayer as long as they stay till the job is done, and as said before, stuff that dosnt want to be dug will not be dug with a bayer. If I had the chance to pick how a dog worked it would be one that bayed but would always be willing to put in that wee bit extra when needed, I wouldnt call that a bayer though
think your better sticking to your dog that does 12 foxes in 4 hours you will not go wrong with that one and a machine gun
