My wife makes & sells fabric collars, so I'm kinda stuck? Actually, she makes Martingale collars (which are similar to a choke, but with built in limits), & they work very well for Zoomie. He doesn't really pull, & the collar "checks" him if he does. The downfall is that my wife sews them from various fabrics, & they don't hold up too well. The upshot is that I'm married to the manufacturer, so I can get all I want!
