Herm Sprenger Black Stainless Steel Ultra-Plus Prong Collar for German Shorthaired Pointer with Center-Plate and Assembly Chain - 3.2 mm x 23 inches

It’s the real deal !I have 13 month old Doberman alpha female and she’s horrible on leash despite being trained. I put this on and the difference was almost immediately noticed as she walked next to me even when other dogs were loose. I have had other prong collars but I couldn’t remove the parts and they were too wide. (She’s petite dobe). This one fits perfectly (after removing 2 parts) and it’s easy to close. The colour is perfect barely noticeable on her neck.

It stopped my dog from pulling me along. I can now maintain control a lot easier
