I am just going to address the snap issue since I and many other bulldog guys won't use any type snap. I made my own swivels for years using 3/8 " round stock to make a ring the collar goes through and an eyebolt with a nut welded to it. You have to remove the collar to take the dog on and off but I never had a failure. Gary Hammonds and Floyd Boudreaux will both tell you they are as secure as you can get.
If you get the time could you please take some pictures of your set up and send them to me? I would like to see what you have.
