Herm SprengerChrome Plated Prong Dog Collar Ultra-Plus Pet Pinch Collar with Two O-Rings No-Pull Collar for Dogs Anti Pull Training Collar Made in Germany (23in x 3.2mm (Neck Size up to 19in))

i have a 90 pound lab that loves to pull and mark everything. now he doesn't anymore.

I’ve known Sprenger quality from horse bits and this dog collar is no exception to the quality of product. Used as a corrective tool in the right hands, a prong collar like this can help set boundaries for your dog and get them walking on a loose leash. I highly recommend working with a professional on this to make sure your timing is perfect so you aren’t unnecessarily punishing and frustrating your dog.

Dog morphed, from sled dog into service dog in 30 seconds.

I HAVE 2 11-MONTH-OLD SILVER LABS THAT WEIGHT AREOUD 70-75 POUNDS EACH! THEY USED TO TUG ME AROUND EVERY WHERE. SINCE THESE COLLARS, THEY ARE VERY EASY TO CONTROL, WHETHER 1 AT A TIME OR WALKING THEM TOGETHER. THE COLLARS HAVE BEEN HEAVEN SENT! THEY DON'T HURT MY PUPS BUT THEY GET THEIR ATTENTION SO THEY LISTEN TO COMMANDS AND HEAL VERY NICELY NOW.

Collar makes walls with my 90# Doberman pleasurable. It is not quite as easy to insert the link as I thought it should be, but getting the hang of it

70lb mutt, only after a few uses..

Quality quality quality. Very well made collar, much stronger than off brands from petsmart. Used on a male lab for training, stainless steel very nice.
