Heavy Duty 6mm choke collar is great for controlling a strong dog (looks good too).
Choosing The Correct Size:
The Chain size is measured from the end of 1 ring to the other. Therefore the best way to get the correct size on these is to measure your dog's actual neck and add at least 3" - 4".
Ex. Dog's neck measures 20" add 4" for correct size of 24". *For sizes in between, we recommend you choose the larger size. Also consider your dog's head size, if your dog's head is bigger then their neck then you will not be able to get the collar over his head unless you choose a size that will fit over their head.
