Soft Slip™ Collar Fit & Safety
The SoftSlip™ is fit just like any other Limited Slip design collar: The collar goes on over your dog's head (like the old choke training collar, or show collar) with the end or "live" ring to the dog's right. This is also the ring to which a lead is attached. Any tags should be attached to the other ring, the passive ring. If there is any webbing doubled because of tightening the slide adjustment, be sure it goes to the side opposite the slip section or the collar will not slip and release.
When the collar is properly adjusted, pulling on the "live" or end ring will cause the collar to tighten around your dog's neck, but not to the point of choking, while at the same time not allowing the dog to "back out" of the collar. If you have an escape artist, make sure, as you would with any collar, that you double check to see that the collar is snug enough.
For my own dogs I place the collar at the narrowest part of the neck, just behind the ears, pull on the "live" ring so that it snugs up around the dog's neck, then check to see that I can get a couple of fingers (flat) between the collar and the dog's neck. This way my dog can't back out of the collar, yet there will be no choking.
Fitting adjustments are easiest to do with the collar off of your dog. As you would with any collar, always check the collar after any adjustment. If you have a coated breed check the adjustment as she/he is losing coat or growing in new coat — with a heavily coated breed it can make a difference.
