This is Rocco. Rocco likes his dog collar from Combat K9 in Multi-Cam. Rocco is a bad ass who gets all the bitches (literally). He wears only the tacticoolest kit. Yes, even MWDs, police canines and other working dogs know tacticool when they see it. Described as "the strongest, toughest, and longest lasting dog collar on the market," it is rated to hold up to 900lbs, will adjust from 19" to 31", has a stainless steel metal buckle. They have a lifetime guarantee and are made in the USA.
The MC version isn't on the website yet...not sure why that is. Ask about it at info(at)combatk9.com.
You might also look around at Warrior Expo East, if you're lucky enough to be there. Combat K9 might be wandering around there.
