Durable Macho Dog Spike Double Ply Collar for Large Breed Dogs - Heavy Duty Training & Protection Collar for Aggressive Dogs - Perfect for Walking, Guarding, and Outdoor Adventures

One part tough, two parts awesomeness. The cool-factor shines through the blunt-tip spikes on the collar. Besides being extremely tough from the 2 layer of super thick nylon webbing, the spikes throughout add a touch of toughness without going too far as becoming cheesy.  Yeah, this is one tough collar, there's no question about that, but being 1.75 inches in width also helps spread the pressure around your pup's neck when pulling occurs.
