smarlowe,
I don't think their is one type of dog that can catch a hog. But probably the best dog is a fast track dog that is silent...then this dog must do all it can to keep the hog from running...and that dog shouldn't apply any pressure if the hog isn't trying to break...to me the hog needs to feel that it is safer to not run than to run...but like it has been said in the past...some hogs will not hold bay because they have been dogged enough and they have learned to run... and then we have evolution that has helped the survival of the hogs..we as doggers have been the biggest reason why these hogs have evolved to what they are today...otherwise they would all have been caught by now...
Rockin Roo brought up the fact that hogs run more today than way back when...We have discussed this many times here on ETHD.
A lot of us believe in 2 things...one is that the hogs learn and adapt...2. the easy hogs have been caught and the ones that get away are the ones that will pass on their genes... and these hogs prefer flight rather than fight...but these hogs are ferocious when cornered or when pushed into a fight.
One thing I have noticed over the years is that the ones with the floppy ears that looked like barnyard hogs would rather fight than run. The runners tend to look like russian hogs with the smaller pricked ears and the tall shoulders and the smaller rear end...skin out a runner and you will see the power and an animal that is built for speed...the power is balanced but it is exaggerated up on their shoulders and the top of the neck... the offspring of these type of hogs are usually are born red with black stripes or black with red stripes...
I write like it is fact...
but these are opinions and beliefs that I have developed over the years... and... we learn from each others way of thinking...and that is a good thing...
