This curogan dog pinch collar will please with its functionality, anti-allergenic and anti-stain features. The collar consists of a center plate, assembly chain, 2 O-rings and symmetrically arranged prongs. The center plate guarantees an equal distribution of pressure along the collar. Two O-rings serve for leash attachment. The prongs are evenly arranged around the length of the collar. So, when the dog starts to pull, the tension affects all around the neck. And it means less neck injuries.  
This training collar is made of curogan. It is a copper-tin-alloy with a high copper portion and some additives which make the material resistant to rust. There is no nickel, that is why these prongs avoid a discolouration of light-coated dogs. A further advantage of curogan is that it doesn’t provoke allergic reactions and skin rashes. So, it is recommended for dogs with sensitive skin. In addition, a high copper portion gives the collar a brilliant color. However, it antiques and darkens over time with regular use (the original look can be easily restored with the use of a polishing paste).
 
NOTE! This curogan collar is suitable for dogs with any fur color and those canines who are reactive to nickel. This metal avoids a discoloration of light-haired dogs, however some dogs (1 dog in 10) do react on curogan with a discoloration.
 
All Herm Sprenger pinch collars come in a standard length which is adjusted to fit the neck of the dog by removing or adding links.
