THanks for the advice everyone.
We have tried the skinny collar trick and I swear this dog can breath through his ears.
T-Bob, we have had to use the old trim the ear a bit trick. LOL
I will keep trying different things until I find a method that works for me and VooDoo. Like Goose said, its a lot of trial and error. The pit that we used to have, Ammo (RIP) was fairly easy to choke off but his neck wasn't nearly as thick as VooDoo's neck. Maybe I just need to go to the gym.
