I had a heavy Skull bred male once that had bad habits. Lets just say he rented his wood house by the day. It was of no use on the second day and by the third day its only purpose would be kindling. He went after concrete bowls, houses, chains, rocks, whatever. I ended up with him in a 10X10 pen with a car tire. He fought that tire relentlessly, maybe 16-18 hours per day, sometimes all thru the night. As long as the tire was there the dog houses and the concrete bowl were safe. (granted a 10X10 is not recommended for most bulldogs, but with the tire in there he had no desire to go anywhere).

A few years later I visited a yard and we were talking dogs and this guy had my dog's littermate brother. He was a digger. This dog was on a 8ft or so chain, the chain was stretched and tight, and all you could hear was barking and digging, but no dog. He was completely out of sight. He had a hole that was at least 4, maybe five feet deep. Half of the axle was exposed. The guy had welded re-bar to the axle and poured concrete around the axle, maybe 8" in diameter of concrete. The dog dug a hole so deep the first axle just turned over into the hole with him.

So it happens. On a side note I have always wondered why more of the bad habit/hard kept dogs did not die from swallowing barrels, wood, rocks and roots. I am sure some do but one would think the tract could only hold and pass so much plastic, wood or rocks.

Like Jack said, I would make sure that determined guy gets every chance any other dog would. EWO
