Jack could you elaborate a little more on how long or far that Ole timer walked his dogs while pulling that 15 foot chain? Sure he used different weighted chains for the size dog pulling it. The only person that I saw personally work dogs like this was A. Howle along with some round table work.

Never saw his dogs get in trouble for air and were strong as bulls. Always had a big boned dog for the weight. A weak built dog or a dog with any type physical problem, would not hold up long to a keep like that. That chain would definitely bring out the weak links in the dog's body if they are there. LOL
