I have only been doggin for acouple of years, so you can take my opinion for what its worth. All the dogs I hunt with are Ben bloodlines from 4-D Kennels out of N.M. I am really impressed with these dogs agility and heart. My best dog is 4-D Thor which is out of SD Zeus x Wrights Western Tia. Thor has plenty of drive and very gritty, when he hits the ground he is always suited up. I'm sure there are many different bloodlines and breeds that are great hog dogs too but the Ben bloodline is what I use. Just my .02.
Sounds like a good one! I dont perfer gritty so I am hoping mine will take to the dogs i am hunting him with.
