Herm Sprenger Q&A about Curogan

Can collars made of CUROGAN cause fur discoloration?
Even a CUROGAN chain does not completely protect the dog from fur discoloration. This is mainly due to the fact that various factors play a role in the discoloration of the dog’s coat.
CUROGAN is 100% nickel-free and has proven to be a good alternative for dogs that react with a discoloration of the coat. However, even a CUROGAN chain does not prevent by 100% from discoloration of the coat, especially.

Why does my CUROGAN chain turn green?
The discoloration of the chain is caused by the high copper content of a CUROGAN chain. The CUROGAN chain is therefore coated with Zapon lacquer during the final stage of production. This abrades over time so that the material regains its natural surface. Without the lacquer, CUROGAN can develop a greenish discoloration due to temperature variations and high humidity or water influences. However, the quality of the chain is not affected. The original condition can be re-established at any time with a commercially available polishing paste (Diamond paste).
