How to use a slip chain collar
Make the chain into a "P"
Sit your dog down facing you and pull the chain through one of the "O" rings to form a "P"
Slip it on the dog
Your dog will get use to slipping his head through the loop - then attach your lead.
Slip chain or correction collars should only be used when you are actually training your dog. When placed properly and you put on the leash, the collar should tighten and immediately loosen, so only a simple correction is made.
Steps for proper placement
Sit your dog down in front of you, facing you.
Push the chain through one of the O-rings at the end of the collar until the two “Os” meet.
Hold collar in both hands so that it makes the letter P to you (as in “puppy”).
Slip the collar over your dog’s head through the open part of the P.
Attach the leash to the end ring that does not have the collar sliding through it.
From the O-ring attached to the leash the chain links should run through the second O-ring, over the dog’s neck, under his throat, and back to the second O-ring. You can tell if the collar is not placed correctly if the chain links come from under the dog’s neck and through the second O-ring.
Try it out. When you give a short correction and the collar is placed properly, the chain should loosen right after you cease putting pressure on it. Some people add a little weight to the ring so it loosens quickly.
When a chain or slip collar is not placed properly and you pull on the leash end, the collar does not loosen immediately. This means your dog is getting constant correction, even when he has done nothing wrong. The tightening of the collar becomes meaningless to him.
And remember to pull back at the height of the dog, not pull upwards.
There is a good deal of controversy about the use of slip chain collars. Used correctly, they are a long standing and proven method of training a dog. The dog is corrected immediately so there is no confusion about what you are trying to teach.
