Herm Sprenger Stainless Steel Prong Collar
I've used this collar on my German Shepherd puppy since she was about 3 months old. She's 7-month old now and weighs about 55 lbs. It has worked great -- she never pulls on the leash. If she wanders around, a little tug brings her right back. This is a high-quality collar made from stainless steel, and I've never had it come loose but it can happen. Make sure to use the right number of links.
