Review on Herm Sprenger Black Stainless Steel Prong Dog Training Collar: No-Pull German-Made Swivel Ultra-Plus Pet Pinch Collar for Effective Anti-Pull Training by Patty Yenbamroong

EXCELLENT spiked collar! DO NOT rely on other reviews. I have been training dogs for over 20 years. The HermSpringer brand is the best. I like the 2.25mm link size for young and older dogs. The black color blends into my dog's coat and has not yet faded with daily use. Other reviews of this collar (or any other prong collar) just "falling off" or not staying on come from owners who don't know how to use the collar properly. notched collar. The collar should fit snugly, not "hang". The tightness creates a slight tension on each prong, preventing them from slipping and falling off. When squeezing the pins to remove the collar, you sometimes have to spread the pins slightly to get them snug. So if they slip, open them back up slightly. I will buy more of these!
