Bit chancy if you come across a big one? The size in dog's crossed to Bull Arabs, Danes, Wolfhounds and Mastiffs etc. is all about the safety of the hunter and the dog. They can lug and protect you from a big one and not get hurt as easily themselves. That's the way I see it anyway. If it works for you and your feel safe then that's good too. Smaller dogs and bailers are great if your using a gun to dispatch but I reckon it could get a bit dicey with a big boar if you were using a knife.
