They look like an alright type for pigs. We had a English bull/Eng Mastiff/Dane that was surprisingly fast in a sprint, a top pig dog and caught a deer once(only because he was told too) but he was from a line of hunters. I think if you want to create or recreate a breed of this type you need to work all gens and be ruthless in the culling to put a breed stamp on them or they are just a designer dog like a chug. Saying they can catch all game is laughable, my whippets are more allrounders, lol.
