I see it posted all the time about a hog not walking or dragging a dogo around in the woods and I kinda shake my head each time. I typically hunt a couple of curs and one lead in catch dog, that dog just happens to be a dogo right now. I've hunted both and owned both pits and dogos but I'm here to tell you a full grown boar hog (250lbs) can drag one dogo all over the place. It doesn't matter how he catches, ear, snout, jaw, front leg, straddles the hog, pulls on the ear, shakes or stands put.....it's going to drag that dog around. Now I don't think he's going to run off with a dogo hanging on his ear like he may with a 40lb pit but that pit will still be locked, if he's a good one, until the end just like a good dogo should be.
But to say a hog can't drag a dogo around is bull honkey. On the other hand two good dogos can probably secure most any hog if they catch and hold, just like two bulldogs should be able to.
Just my opinion. I like the dogo but they aren't for everyone and they aren't the perfect cure all catch dog.
