The Rings

Choosing a ring form

There are several types of rings used for fasteners on collars. Apart from the quality of material used the two main families are the "O" form rings and the "D" form rings. When you have a dog which pulls on its collar some basic observations should be made. Check that the ends of the ring are welded, it is preferable to have ends welded rather than joined end to end, when there is a deformation due to traction the ring will remain closed whereas the ring with the joined ends will open and 80 times out of 100 will break.

On a collar, as the "D" ring always remains place without even turning on itself, wear is always on the same place and according to the width of the head snap  used, this wear can happen very quickly. The abrasion on the "D" ring  will cause to weaken the point undergoing the most traction and the ring will open at this precise point. Snaps with the larger heads, like the security snaps, make more damage than snaps with fine heads. Ring wear Still on a collar, the "O" ring can turn on itself and thus wear is distributed more or less evenly on the entire ring circumference. Because of its "O" shape, it is easier to pass a finger to hold a dog by the collar and according to the size of this ring, it is even possible to hold the dog with gloves on. With glove on
