I need some advice on a very good collar for my Lab. He is 6 years old and not neutered. He has been running off frequently from the wife and kids. If I'm home and take him out he will stay with me. He just will not listen to the wife or kids and I need him to as I am on the road from time to time. The other day my son was going out the friont door to get the mail and the dog busted out in front of him and blasted up the sidewalk. They went after him but he never looked back and took off running. I need a collar that will stop him in his tracks at a distance for these occasions. I've heard some negatives about the electric fence deal and believe that once he got past it he would just go so I am interested more in the collar. Thanks in advance for any suggestions.
